开发过程中发现需要用到改变鼠标样式（就是光标的样子），但是在网上找了很多资料，都是介绍在程序中使用，我需要的效果时在系统级使用。现在找到了，分享给大家。
1 [DllImport("user32")] 2 private static extern IntPtr LoadCursorFromFile(string fileName); 3 4 [DllImport("User32.DLL")] 5 public static extern bool SetSystemCursor(IntPtr hcur, uint id); 6 public const uint OCR_NORMAL = 32512; 7 8 [DllImport("User32.DLL")] 9 public static extern bool SystemParametersInfo(uint uiAction, uint uiParam,IntPtr pvParam, uint fWinIni); 10 11 public const uint SPI_SETCURSORS = 87; 12 public const uint SPIF_SENDWININICHANGE = 2; 13 14 private void button_Click(object sender, RoutedEventArgs e) 15 { 16 //设置 17 IntPtr iP = LoadCursorFromFile(@"D:\My Files\图片\cursor.cur"); 18 SetSystemCursor(iP, OCR_NORMAL); 19 } 20 21 private void button1_Click(object sender, RoutedEventArgs e) 22 { 23 //恢复 24 SystemParametersInfo(SPI_SETCURSORS, 0, IntPtr.Zero, SPIF_SENDWININICHANGE); 25 }
