本文实例讲述了C#实现简单屏幕监控的方法。分享给大家供大家参考。具体如下：

这是一段C#编写的屏幕监控代码，可以自动对屏幕进行截图，软件自身隐藏

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
namespace Screen 
{ 
 public partial class Form1 : Form 
 { 
  public Form1() 
  { 
   //主窗体桌面不显示 仅在进程中显示 
   InitializeComponent(); 
   this.WindowState = FormWindowState.Minimized; 
   this.ShowInTaskbar = false; 
   SetVisibleCore(false); 
  } 
  protected override void SetVisibleCore(bool value) 
  { 
   base.SetVisibleCore(value); 
  } 
  private void timer1_Tick(object sender, EventArgs e) 
  { 
   //获得当前屏幕的大小 
   Rectangle rect = new Rectangle(); 
   rect = System.Windows.Forms.Screen.GetWorkingArea(this); 
   Size mySize = new Size(rect.Width, rect.Height); 
   Bitmap bitmap = new Bitmap(rect.Width, rect.Height); 
   Graphics g = Graphics.FromImage(bitmap); 
   g.CopyFromScreen(0, 0, 0, 0, mySize); 
   string ImageName = DateTime.Now.ToString("yyyyMMdd_hhmmss") + ".jpg"; 
   bitmap.Save("F://screen//" + ImageName); 
   //释放资源 
   bitmap.Dispose(); 
   g.Dispose(); 
   GC.Collect(); 
  } 
  private void Form1_Load(object sender, EventArgs e) 
  { 
   timer1.Enabled = true;//激活timer控件 
  } 
 } 
}

希望本文所述对大家的C#程序设计有所帮助
