C#实现刷新桌面的方法

本文实例讲述了c#实现刷新桌面的方法。分享给大家供大家参考。具体如下：

using system;
using system.collections.generic;
using system.linq;
using system.text;
using system.runtime.interopservices;
namespace fileencryptproject.algorithm

  public class desktoprefurbish
  {
    /// <summary>
    /// 桌面刷新
    /// </summary>
    [dllimport("shell32.dll")]
    public static extern void shchangenotify(hchangenotifyeventid weventid, hchangenotifyflags uflags, intptr dwitem1, intptr dwitem2);
    public static void deskref()
    {
      shchangenotify(hchangenotifyeventid.shcne_assocchanged, hchangenotifyflags.shcnf_idlist, intptr.zero, intptr.zero);
    }
  }

  }
  #endregion//enum hchangenotifyflags

    shcne_updatedir = 0x00001000,
    shcne_updateimage = 0x00008000,
  }
  #endregion
}

希望本文所述对大家的c#程序设计有所帮助。
