如何在整个windows操作系统中更改光标(图像)
本文关键字：光标 图像 操作系统 windows | 更新日期: 2023-09-27 18:00:33
我需要在所有窗口中更改光标，而不仅仅是在应用程序中，我已经尝试过了：
this.Cursor = Cursors.WaitCursor;
这个：
System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.WaitCursor;
但它只会更改我的应用程序中的光标。
知道吗？
假设你有自己的游标文件（.cur）要应用，你可以破解它。
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系统参数，从而使光标实际发生更改。
类似
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，就无法更改整个操作系统的光标
您需要修改注册表来更改光标。
