[StructLayout(LayoutKind.Sequential)]         public struct POINT         {             public int X;             public int Y;               public POINT(int x, int y)             {                 this.X = x;                 this.Y = y;             }               public override string ToString()             {                 return ("X:" + X + ", Y:" + Y);             }         }           [DllImport("user32.dll", CharSet = CharSet.Auto)]         public static extern bool GetCursorPos(out POINT pt);

使用：

POINT currentPosition = new POINT();                 GetCursorPos(out currentPosition);                   System.Diagnostics.Debug.WriteLine("Current mouse point: " + currentPosition.ToString());

//转为客户区域坐标                 Point relativePos = itemsControl.PointFromScreen(new Point(currentPosition.X, currentPosition.Y));
