C#如何修改桌面上鼠标指针形状

运行c#开发的程序，修改可以修改桌面上的鼠标指针的形状，例如从箭头改成等待形状。
注意：是通过写代码修改哦，而不是控制面板的修改入口。
谢谢！

[DllImport("user32.dll")]
static extern IntPtr LoadCursorFromFile(string lpFileName);

[DllImport("user32.dll")]
static extern IntPtr SetCursor(IntPtr hCursor);

[DllImport("user32.dll")]
static extern bool SetSystemCursor(IntPtr hcur, uint id);

private const uint OCR_NORMAL = 32512;

static Cursor ColoredCursor;
//==========C# Only
//========SET WINDOWS CURSOR========================================
IntPtr cursor = LoadCursorFromFile("example.cur");
bool ret_val = SetSystemCursor(cursor, OCR_NORMAL);

//========SET WINDOWS CURSOR========================================
//========SET FORM CURSOR========================================
IntPtr cursor = LoadCursorFromFile("example.cur");
ColoredCursor = new Cursor(cursor);
this.Cursor = ColoredCursor;

//========SET FORM CURSOR========================================
//========SET FORM CURSOR FROM IMAGE========================================
Bitmap hh = (Bitmap)System.Drawing.Bitmap.FromFile("example.png");
Graphics.FromImage(hh);
IntPtr ptr = hh.GetHicon();
Cursor c = new Cursor(ptr);
this.Cursor = c;
