winfrom鼠标点击位置

//内容待整理

private void From1_MouseClick(object sender, MouseEventArgs e)

        {
            Point p = e.Location;
            string X = p.X.ToString();
            string Y = p.Y.ToString();
            MessageBox.Show(p.ToString(),X+Y);           

        }

API函数

[DllImport( "user32.dll" )]
        private  static  extern  bool  GetCursorPos( out  Point p);

使用
            Point p;
            GetCursorPos( out  p);

.Net封装好的方法

int x = Control.MousePosition.X;
int y = Control.MousePosition.Y;

用API方法

using System.Runtime.InteropServices;
Point p;
[DllImport("user32.dll")]
public static extern bool GetCursorPos(out Point pt);
private void timer1_Tick(object sender, EventArgs e)
{
   GetCursorPos(out p);
   label1.Text = p.X.ToString();//X坐标
   label2.Text = p.Y.ToString();//Y坐标
}

可以用Control.MousePosition获得当前鼠标的坐标，使用PointToClient计算鼠标相对于某个控件的坐标，如下
Point screenPoint = Control.MousePosition;//鼠标相对于屏幕左上角的坐标
            Point formPoint = this.PointToClient(Control.MousePosition);//鼠标相对于窗体左上角的坐标
            Point contextMenuPoint = contextMenuStrip1.PointToClient(Control.MousePosition); //鼠标相对于contextMenuStrip1左上角的坐标
