一、音频文件上传和播放

>>上传

protected void Button1_Click(object sender, EventArgs e)
{

         foreach (UploadedFile file in RadUploadContext.Current.UploadedFiles)
            {
                if (file.FileName != null && file.FileName != "")
                {
                    string strTime = memberid.ToString() + "-" + DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Millisecond.ToString();
                    string namefile = file.FileName;//获取文件原来的名字
                    string namelast = namefile.Substring(namefile.LastIndexOf("."));//获取文件的后缀名,LastIndexOf()-返回括号内字符的所在位置
                    string FilePath = System.AppDomain.CurrentDomain.BaseDirectory + @"SaveFilePath/MBmusic/";//文件上传的路径
                    System.IO.FileInfo fi = new System.IO.FileInfo(file.FileName);
                    if (fi.Extension.ToLower() == ".mp3" || fi.Extension.ToLower() == ".wma" || fi.Extension.ToLower() == ".rm" || fi.Extension.ToLower() == ".wav")
                    {
                        string name = strTime + namelast;//文件最后保存的名字
                        mv = "http://www.cnblogs.com/SaveFilePath/MBmusic/" + name;
                        Filesizes = int.Parse(file.ContentLength.ToString());
                        string path = FilePath + name;
                        if (File.Exists(path) == false)
                        {
                            file.SaveAs(FilePath + name);
                            mf.MF_Path = mv;
                            //mf.MF_Path = mv;
                        }
                        else if (File.Exists(path) == true)
                        {
                            name = strTime + "(" + tt + ")" + namelast;
                            file.SaveAs(FilePath + name);
                            mv = "http://www.cnblogs.com/SaveFilePath/MBmusic/" + name;
                            mf.MF_Path = mv;
                            //mf.MF_Path = mv;
                        }
                        if (RemainByteSize >= Filesizes)
                        {
                            try
                            {

                                //将数据插入数据库
                                 if (addnum > 0 && udpsize > 0)
                                {
                                    //Response.Write("<script>alert('上传成功!!')</script>");
                                    //Bind();
                                }
                                else
                                {
                                    Response.Write("<script>alert('上传失败!!')</script>");
                                    return;
                                }
                                num++;
                            }
                            catch { }
                        }
                        else
                        {
                            Response.Write("<script>alert('空间不足，请申请空间!!')</script>");
                            return;
                        }
                    }
                    else
                    {
                        Response.Write("<script>alert('上传文件格式错误! 文件格式为mp3,wma,wav.rm的视频!')</script>");
                        return;
                    }
                }
                else
                {
                    Response.Write("<script>alert('请选择上传的文件')</script>");
                    return;
                }
            }
    }

>>播放

1、在播放页面添加控件Literal1 控件

2、在页面后台添加调用音频播放器代码

       public static string GetFlashText(string url)
    {
        string str = @"<object id='MediaPlayer' classid='clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6' height='62' width='406'>
   <param name='rate' value='1' />
   <param name='balance' value='0' />
   <param name='currentPosition' value='0' />
   <param name='defaultFrame' value='' />
   <param name='playCount' value='1' />
   <param name='autoStart' value='-1' />
   <param name='currentMarker' value='0' />
   <param name='invokeURLs' value='-1' />
   <param name='baseURL' value='' />
   <param name='volume' value='2' />
   <param name='mute' value='0' />
   <param name='uiMode' value='full' />
   <param name='stretchToFit' value='0' />
   <param name='windowlessVideo' value='0' />
   <param name='enabled' value='-1' />
   <param name='enableContextMenu' value='0' />
   <param name='fullScreen' value='0' />
   <param name='SAMIStyle' value='' />
   <param name='SAMILang' value='' />
   <param name='SAMIFilename' value='' />
   <param name='captioningID' value='' />
   <param name='enableErrorDialogs' value='0' />
   <param name='_cx' value='10742' />
   <param name='_cy' value='1799' />
            <param name='URL' value='"+url+"'/></object>";
        return str;
    }

3、调用GetFlashText()方法

public void BindMusic()
{

if (mfid != 0)
        {
            DataSet dst = mf.Search(mfid);
            if (dst != null && dst.Tables[0].Rows.Count > 0)
            {
                string url = dst.Tables[0].Rows[0]["MF_Path"].ToString();

            string[] strs = url.Split(new char[] { '/' });
            string mvname = strs[strs.Length - 1];
            string url1 = "SaveFilePath/MBmv/" + mvname;
                Literal1.Text = GetFlashText(url);//Literal1调用方法播放音频
             Label1.Text = dst.Tables[0].Rows[0]["MF_FileName"].ToString();
                //txt_FileName.Text = dst.Tables[0].Rows[0]["MF_FileName"].ToString();
                //txt_introduction.Text = dst.Tables[0].Rows[0]["MF_Introduction"].ToString();
            }
        }
    }
