C# 设置鼠标光标位置

using System.Drawing;
using System.Runtime.InteropServices;

namespace ZB.QueueSys.Common
{
    public class MouseHelper
    {
        private static MouseHelper instance;
        public static MouseHelper Instance
        {
            get
            {
                if (instance == null) instance = new MouseHelper();
                return MouseHelper.instance;
            }
        }

        /// <summary>
        /// 引用user32.dll动态链接库（windows api），
        /// 使用库中定义 API：SetCursorPos 
        /// </summary>
        [DllImport("user32.dll")]
        private static extern int SetCursorPos(int x, int y);
        /// <summary>
        /// 移动鼠标到指定的坐标点
        /// </summary>
        public void MoveMouseToPoint(Point p)
        {
            SetCursorPos(p.X, p.Y);
        }
        /// <summary>
        /// 设置鼠标的移动范围
        /// </summary>
        public void SetMouseRectangle(Rectangle rectangle)
        {
            System.Windows.Forms.Cursor.Clip = rectangle;
        }
        /// <summary>
        /// 设置鼠标位于屏幕中心
        /// </summary>
        public void SetMouseAtCenterScreen()
        {
            int winHeight = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height;
            int winWidth = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width;
            Point centerP = new Point(winWidth / 2, winHeight / 2);
            MoveMouseToPoint(centerP);
        }

    }
}


调用测试如下：
            int y = Screen.PrimaryScreen.WorkingArea.Height - 180;
            int x = Screen.PrimaryScreen.WorkingArea.Width - 180;
            Point p = new Point(x, y);
            MouseHelper.Instance.MoveMouseToPoint(p);

C#获取指定控件所在屏幕的位置

　　　　　 int x = this.dgvList.Location.X;
            int y = this.dgvList.Location.Y;
            Point p = new Point(x, y);
            Point pp = this.dgvList.PointToScreen(p);
            MouseHelper.Instance.MoveMouseToPoint(pp);
