C#实现位图转换成图标的方法

本文实例讲述了c#实现位图转换成图标的方法。分享给大家供大家参考。具体实现方法如下：

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 form23 : form
  {
    public form23()
    {
      initializecomponent();
    }
    private void button1_click(object sender, eventargs e)
    {
      bitmap bmp = new bitmap(@"d:/我的文档/桌面/ico/watermark.bmp");
      intptr hicon = bmp.gethicon();
      icon icon=icon.fromhandle(hicon);
      this.icon = icon;
      graphics g = this.creategraphics();
      //g.drawicon(icon, this.clientrectangle);
      g.drawiconunstretched(icon, this.clientrectangle);
    }
  }
}

希望本文所述对大家的c#程序设计有所帮助。
