C#制作简易播放器

.net framework里有了许多COM组件,我们可以根据应用程序的需要来使用这些组件，不用自己再去 “造轮子”了。

 

第一个示例是来制作一个VCD播放器.这里我使用了Windows自带的Media Play来播放多媒体文件。

选择‘工具箱’—‘组件’，右击，选择‘添加/移除项’—‘COM组件‘（如果你是第一次使用Windows Media Play控件，在列表中是没有这个控件的，可以在系统文件夹下找到，一般是在C:/Windows/System32/msdxm.ocx，把这个控件加入到控件列表中，就可以使用了。

代码如下：

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace MPlayDemo
{
    public class Form1 : System.Windows.Forms.Form
    {
        private AxMediaPlayer.AxMediaPlayer axMediaPlayer1;
    
    
        public Form1()
        {
            InitializeComponent();
        }

            #region 
        private void InitializeComponent()
        {
            this.axMediaPlayer1 = new AxMediaPlayer.AxMediaPlayer();
            // 
            // axMediaPlayer1
            // 
            this.axMediaPlayer1.Dock = System.Windows.Forms.DockStyle.Top;
            this.axMediaPlayer1.Location = new System.Drawing.Point(0, 0);
            this.axMediaPlayer1.Name = "axMediaPlayer1";
            this.axMediaPlayer1.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("axMediaPlayer1.OcxState")));
            this.axMediaPlayer1.Size = new System.Drawing.Size(488, 376);
            this.axMediaPlayer1.TabIndex = 0;
        }
        #endregion

        private void btnPlay_Click(object sender, System.EventArgs e)
        {
            if(this.axMediaPlayer1.FileName.Trim()=="")
            {
                MessageBox.Show(this," 请选择要播放的文件!!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
                return;
            }
            this.axMediaPlayer1.Play();
        }

        private void btnPause_Click(object sender, System.EventArgs e)
        {
            if(this.axMediaPlayer1.FileName.Trim()=="")
            {
                MessageBox.Show(this," 请选择要播放的文件!!!"," 信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
                return;
            }
            this.axMediaPlayer1.Pause();
        }

        private void btnStop_Click(object sender, System.EventArgs e)
        {
            if(this.axMediaPlayer1.FileName.Trim()=="")
            {
                MessageBox.Show(this,"请选择要播放的文件","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
                return;
            }
            this.axMediaPlayer1.Stop();
        }


        private void menuItem3_Click(object sender, System.EventArgs e)
        {
            Application.Exit();
        }

        private void menuItem2_Click(object sender, System.EventArgs e)
        {
            this.openFileDialog1.ShowDialog();
            string strFileName = this.openFileDialog1.FileName;
            if(strFileName.Trim()=="")
                return;
            this.axMediaPlayer1.FileName = strFileName;

        }

        private void menuItem4_Click(object sender, System.EventArgs e)
        {
                    this.axMediaPlayer1.AboutBox();
        }

        private void menuItem5_Click(object sender, System.EventArgs e)
        {
            this.axMediaPlayer1.FastForward();
    
    }
}

第二个示例是制作一个DVD播放器：

选择‘工具箱’—‘组件’，右击，选择‘添加/移除项’—‘COM组件‘把“MSWebDVD
”这个控件加入到控件列表中，就可以使用了。

代码如下：

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace DVDPlayDemo
{
    public class Form1 : System.Windows.Forms.Form
    {
        private AxMSWEBDVDLib.AxMSWebDVD axMSWebDVD1;
    

        

        Windows#region Windows                
        private void InitializeComponent()
        {
                this.axMSWebDVD1 = new AxMSWEBDVDLib.AxMSWebDVD();
        
            // 
            // axMSWebDVD1
            // 
            this.axMSWebDVD1.Dock = System.Windows.Forms.DockStyle.Top;
            this.axMSWebDVD1.Enabled = true;
            this.axMSWebDVD1.Location = new System.Drawing.Point(0, 0);
            this.axMSWebDVD1.Name = "axMSWebDVD1";
            this.axMSWebDVD1.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("axMSWebDVD1.OcxState")));
            this.axMSWebDVD1.Size = new System.Drawing.Size(504, 320);
            this.axMSWebDVD1.TabIndex = 0;

        }
        #endregion

    

        private void btnPlay_Click(object sender, System.EventArgs e)
        {
            try
            {
                this.axMSWebDVD1.Play();
            }
            catch(System.Exception ex)
            {
                MessageBox.Show(ex.Message.ToString());
            }
        }

        private void btnPause_Click(object sender, System.EventArgs e)
        {
            try
            {
                this.axMSWebDVD1.Pause();
            }
            catch(System.Exception ex)
            {
                MessageBox.Show(ex.Message.ToString());
            }
        }

        private void btnStop_Click(object sender, System.EventArgs e)
        {
            try
            {
                this.axMSWebDVD1.Stop();
            }
            catch(System.Exception ex)
            {
                MessageBox.Show(ex.Message.ToString());
            }
        }

        private void btnOut_Click(object sender, System.EventArgs e)
        {
            try
            {
                this.axMSWebDVD1.Eject();
            }
            catch(System.Exception ex)
            {
                MessageBox.Show(ex.Message.ToString());
            }
        }


    }
}

第三个示例是制作一个Flash播放器。选择‘工具箱’—‘组件’，右击，选择‘添加/移除项’—‘COM组件‘把“Shockwave Flash Object”这个控件加入到控件列表中，就可以使用了。

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace FlashPlayDemo
{
    public class Form1 : System.Windows.Forms.Form
    {
    
        private AxShockwaveFlashObjects.AxShockwaveFlash axShockwaveFlash1;
    
    

    

        #region 
        private void InitializeComponent()
        {
        
            this.axShockwaveFlash1 = new AxShockwaveFlashObjects.AxShockwaveFlash();
        
            // 
            // axShockwaveFlash1
            // 
            this.axShockwaveFlash1.Dock = System.Windows.Forms.DockStyle.Top;
            this.axShockwaveFlash1.Enabled = true;
            this.axShockwaveFlash1.Location = new System.Drawing.Point(0, 0);
            this.axShockwaveFlash1.Name = "axShockwaveFlash1";
            this.axShockwaveFlash1.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("axShockwaveFlash1.OcxState")));
            this.axShockwaveFlash1.Size = new System.Drawing.Size(680, 312);
            this.axShockwaveFlash1.TabIndex = 0;
                    }
        #endregion

        private void menuItem2_Click(object sender, System.EventArgs e)
        {
            if(this.openFileDialog1.ShowDialog()==DialogResult.OK)
            {
                this.axShockwaveFlash1.Movie = this.openFileDialog1.FileName;
                this.Text = "播放的是-"+this.openFileDialog1.FileName;
            }

        }

        private void btnPlay_Click(object sender, System.EventArgs e)
        {
            if(this.openFileDialog1.FileName.Length>0)
            {
                this.axShockwaveFlash1.Play();
            }
            else
            {
                MessageBox.Show(this,"请选择文件!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
            }
        }

        private void btnStop_Click(object sender, System.EventArgs e)
        {
            if(this.openFileDialog1.FileName.Length>0)
            {
                this.axShockwaveFlash1.Stop();
            }
            else
            {
                MessageBox.Show(this,"请选择文件!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
            }
        }

        private void btnFisrt_Click(object sender, System.EventArgs e)
        {
            if(this.openFileDialog1.FileName.Length>0)
            {
                this.axShockwaveFlash1.Rewind();
            }
            else
            {
                MessageBox.Show(this,"请选择文件!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
            }
        }

        private void btnLast_Click(object sender, System.EventArgs e)
        {
            if(this.openFileDialog1.FileName.Length>0)
            {
                this.axShockwaveFlash1.Back();
            }
            else
            {
                MessageBox.Show(this,"请选择文件!!!","信息提示“，MessageBoxButtons.OK,MessageBoxIcon.Information);
            }
        }

        private void btnNext_Click(object sender, System.EventArgs e)
        {
            if(this.openFileDialog1.FileName.Length>0)
            {
                this.axShockwaveFlash1.Forward();
            }
            else
            {
                MessageBox.Show(this,"请选择文件!!!","信息提示”，MessageBoxButtons.OK,MessageBoxIcon.Information);
            }
        }


    }
}

第四个示例是制作一个RealPlay播放器。选择‘工具箱’—‘组件’，右击，选择‘添加/移除项’—‘COM组件‘,把“RealPlayer G2 Control”这个控件加入到控件列表中，就可以使用了。

为了简单起见，就直接使用它的控制面板了，代码如下：

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace RealPlayDemo
{
    public class Form1 : System.Windows.Forms.Form
    {
        private AxRealAudioObjects.AxRealAudio axRealAudio1;
            #region 
        private void InitializeComponent()
        {
        
            this.axRealAudio1 = new AxRealAudioObjects.AxRealAudio();
        }
        #endregion

        private void menuItem2_Click(object sender, System.EventArgs e)
        {
            if(this.openFileDialog1.ShowDialog()==DialogResult.OK)
            {
                this.axRealAudio1.Source = this.openFileDialog1.FileName;
                this.axRealAudio1.DoPlay();
            }
        }

        private void menuItem3_Click(object sender, System.EventArgs e)
        {
            Application.Exit();
        }
    }
}

最后一个示例是对第一个Windows Media Play播放器的扩展，用它来制作一个Mp3播放器。选择‘工具箱’—‘组件’，右击，选择‘添加/移除项’—‘COM组件‘,把“Windows Media Play”这个控件加入到控件列表中，就可以使用了。

代码如下：

using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.IO;

{
    
    public class Form1 : System.Windows.Forms.Form
    {
        private AxMediaPlayer.AxMediaPlayer axMediaPlayer1;
    
        #region
        private void InitializeComponent()
        {
            this.axMediaPlayer1 = new AxMediaPlayer.AxMediaPlayer();
            
        }
        #endregion

        private void menuItem3_Click(object sender, System.EventArgs e)
        {
            Application.Exit();
        }

        private void menuItem2_Click(object sender, System.EventArgs e)
        {

                string[] FileNames = this.openFileDialog1.FileNames;
                foreach(string fName in FileNames)
                {
                    System.IO.FileInfo fInfo = new FileInfo(fName);
                    float fSize = (float)fInfo.Length/(1024*1024);
                    this.axMediaPlayer1.FileName = fName;
                    this.axMediaPlayer1.Stop();
                    string author = this.axMediaPlayer1.GetMediaInfoString(MediaPlayer.MPMediaInfoType.mpClipAuthor);
                    string shortFileName = fName.Substring(fName.LastIndexOf("//")+1);
                    shortFileName = shortFileName.Substring(0,shortFileName.Length-4);
                    string[] subItem = {shortFileName,author,fSize.ToString().Substring(0,4)+"M",fName};

                    this.axMediaPlayer1.Play();
                }
                else
                {
                    MessageBox.Show(this,"ÇëÑ¡ÔñÒª²¥•ÅµÄ¸èÇú!!!","ÐÅÏ¢Ìáʾ",MessageBoxButtons.OK,MessageBoxIcon.Information);
