C#开发分享：如何改变系统鼠标样式

C#实现改变鼠标样式

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);

 4         [DllImport("User32.DLL")]
 5         public static extern bool SetSystemCursor(IntPtr hcur, uint id);
 6         public const uint OCR_NORMAL = 32512;

 8         [DllImport("User32.DLL")]
 9         public static extern bool SystemParametersInfo(uint uiAction, uint uiParam,IntPtr pvParam, uint fWinIni);

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         }
