【在窗體上獲取相對於屏幕的坐標：】
方法1：
public class Win32
{
[StructLayout(LayoutKind.Sequential)]
public struct POINT
{
public int X;
public int Y;
public POINT(int x, int y)
{
this.X = x;
this.Y = y;
}
}
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern bool GetCursorPos(out POINT pt);
}
方法2：
Mouse.GetPosition(this)
方法3：
在鼠標mousemove事件中e.GetPosition(this)
【獲取全局鼠標坐標】
