如何在整个Windows操作系统中更改光标（图像）
我需要在所有窗口中更改光标，而不仅仅是在应用程序中，我试试这个：
this.Cursor = Cursors.WaitCursor; 还有这个：
System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.WaitCursor;
但它只会改变我的应用程序中的光标。
任何的想法？
假设你有你自己的光标文件（.cur）来应用你可以破解这个。
首先，您必须更改注册表中的默认箭头光标，然后您需要调用一些P-Invoke以允许操作系统更新当前的系统参数，以便光标实际更改。
像这样的东西：
private void ChangeCursor(string curFile) { Registry.SetValue(@"HKEY_CURRENT_USER\Control Panel\Cursors\", "Arrow", curFile); SystemParametersInfo(SPI_SETCURSORS, 0, null, SPIF_UPDATEINIFILE | SPIF_SENDCHANGE); } const int SPI_SETCURSORS = 0x0057; const int SPIF_UPDATEINIFILE = 0x01; const int SPIF_SENDCHANGE = 0x02; [DllImport("user32.dll", EntryPoint = "SystemParametersInfo")] public static extern bool SystemParametersInfo(uint uiAction, uint uiParam, uint? pvParam, uint fWinIni);
用法：
ChangeCursor(@"C:\MyCursor.cur");
如果不修改注册表，则无法更改整个操作系统的光标。
您需要修改注册表以更改光标。
