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

    /// 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);
    }
  }

    SHCNF_FLUSHNOWAIT = 0x2000
  }
  #endregion//enum HChangeNotifyFlags

    SHCNE_SERVERDISCONNECT = 0x00004000,
    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。
