这篇文章主要介绍了C#实现刷新桌面的方法,涉及C#基于shell32.dll动态链接库实现系统桌面刷新的技巧,具有一定参考借鉴价值,需要的朋友可以参考下
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);
- }
- }
- #region public enum HChangeNotifyFlags
- [Flags]
- public enum HChangeNotifyFlags
- {
- SHCNF_DWORD = 0x0003,
- SHCNF_IDLIST = 0x0000,
- SHCNF_PATHA = 0x0001,
- SHCNF_PATHW = 0x0005,
- SHCNF_PRINTERA = 0x0002,
- SHCNF_PRINTERW = 0x0006,
- SHCNF_FLUSH = 0x1000,
- SHCNF_FLUSHNOWAIT = 0x2000
- }
- #endregion//enum HChangeNotifyFlags
- #region enum HChangeNotifyEventID
- [Flags]
- public enum HChangeNotifyEventID
- {
- SHCNE_ALLEVENTS = 0x7FFFFFFF,
- SHCNE_ASSOCCHANGED = 0x08000000,
- SHCNE_ATTRIBUTES = 0x00000800,
- SHCNE_CREATE = 0x00000002,
- SHCNE_DELETE = 0x00000004,
- SHCNE_DRIVEADD = 0x00000100,
- SHCNE_DRIVEADDGUI = 0x00010000,
- SHCNE_DRIVEREMOVED = 0x00000080,
- SHCNE_EXTENDED_EVENT = 0x04000000,
- SHCNE_FREESPACE = 0x00040000,
- SHCNE_MEDIAINSERTED = 0x00000020,
- SHCNE_MEDIAREMOVED = 0x00000040,
- SHCNE_MKDIR = 0x00000008,
- SHCNE_NETSHARE = 0x00000200,
- SHCNE_NETUNSHARE = 0x00000400,
- SHCNE_RENAMEFOLDER = 0x00020000,
- SHCNE_RENAMEITEM = 0x00000001,
- SHCNE_RMDIR = 0x00000010,
- 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。
