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。
