1.  引入命名空间`using System.Runtime.InteropServices;` 因为要使用user32.dll中的接口。
2.  创建一个新类MouseFlag
3.  声明函数  
    \- 此处的位置都是屏幕绝对位置  
    \- 设置鼠标位置：`public static extern int SetCursorPos(int x, int y);`  
    \- 鼠标事件：`static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);`虽然这个已经弃用了，但是上手简单。这里需要一个类型：MouseEventFlag
4.  创建MouseEventFlag ：`enum MouseEventFlag : uint`
5.  用类包起来

public class MouseFlag
        {
            enum MouseEventFlag : uint
            {
                Move = 0x0001,
                LeftDown = 0x0002,
                LeftUp = 0x0004,
                RightDown = 0x0008,
                RightUp = 0x0010,
                MiddleDown = 0x0020,
                MiddleUp = 0x0040,
                XDown = 0x0080,
                XUp = 0x0100,
                Wheel = 0x0800,
                VirtualDesk = 0x4000,
                Absolute = 0x8000
            }
    
            [DllImport("user32.dll")]
            static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);
    
            [DllImport("user32.dll")]
            public static extern int SetCursorPos(int x, int y);
    
            public static void MouseLefClickEvent(int dx, int dy, uint data)
            {
                SetCursorPos(dx, dy);
                mouse_event(MouseEventFlag.LeftDown, dx, dy, data, UIntPtr.Zero);
                mouse_event(MouseEventFlag.LeftUp, dx, dy, data, UIntPtr.Zero);
            }
        }

*    
    
 *  eg：点击屏幕的（9，1059）.我的这个点是“开始”按钮所在位置

> `MouseFlag.MouseLefClickEvent(9, 1059, 0);`
