本文实例讲述了C#实现屏幕拷贝的方法。分享给大家供大家参考。具体如下：

方法一：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Drawing.Drawing2D;namespace WindowsApplication2{  public partial class Form21 : Form  {    public Form21()    {      InitializeComponent();    }    private void button1_Click(object sender, EventArgs e)    {      Rectangle screenRect = Screen.PrimaryScreen.WorkingArea;      Bitmap dumpBitmap = new Bitmap(screenRect.Width, screenRect.Height);      Graphics tg = Graphics.FromImage(dumpBitmap);      tg.CopyFromScreen(0, 0, 0, 0, new Size(dumpBitmap.Width, dumpBitmap.Height));      this.pictureBox1.BackgroundImage = dumpBitmap;      this.pictureBox1.BackgroundImageLayout = ImageLayout.Stretch;      dumpBitmap.Save(@"c:/image1.bmp");    }  }}

方法二：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace WindowsApplication2{  public partial class Form22 : Form  {    public Form22()    {      InitializeComponent();    }    private void button1_Click(object sender, EventArgs e)    {      Rectangle rect = new Rectangle(0, 0, this.Size.Width, this.Size.Height);      Bitmap dumpBitmap = new Bitmap(this.Size.Width, this.Size.Height);      this.DrawToBitmap(dumpBitmap, rect);      this.pictureBox1.BackgroundImage = dumpBitmap;      this.pictureBox1.BackgroundImageLayout = ImageLayout.Stretch;      dumpBitmap.Save(@"c:/image2.bmp");    }  }}
