C#实现清空回收站的方法

本文实例讲述了c#实现清空回收站的方法。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.linq;
using system.text;
using system.runtime.interopservices;
namespace app
{
 class clearrecycle
 {
  [dllimportattribute("shell32.dll")]
  private static extern int shemptyrecyclebin(intptr handle, string root, int falgs);
  const int sherb_noconfirmation = 0x000001;
  const int sherb_noprogressui = 0x000002;
  const int sherb_nosound = 0x000004;
  /// <summary>
  /// 清空回收站
  /// </summary>
  /// <param name="tip">是否提示</param>
  /// <param name="form">当前窗体，一般传入this</param>
  public static void clear(bool tip, system.windows.forms.form form)
  {
   system.windows.forms.dialogresult result = system.windows.forms.dialogresult.no;
   if (tip)
    result = system.windows.forms.messagebox.show("确定要清空回收站吗?", "友情提示", system.windows.forms.messageboxbuttons.yesno, system.windows.forms.messageboxicon.information);
   else
    result = system.windows.forms.dialogresult.yes;
   if (result == system.windows.forms.dialogresult.yes)
   {
    shemptyrecyclebin(form.handle, "", sherb_noconfirmation + sherb_noprogressui + sherb_nosound);
   }
  }
 }
}

希望本文所述对大家的c#程序设计有所帮助。
