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"); } }}

希望本文所述对大家的C#程序设计有所帮助。
