In C# programming using mouse events is a need for many programmer. Using C#, Mouse positions can be easily used but, we can’t change mouse position or create mouse click.

There is a solutions for this problem. We can use DllImport to access windows APIs, so we can both change mouse position and create click event.

I write a Mouse class because of this need. We can access mouse position, set cursor coordinates and create left and right click events.

    class Fare
    {
        [DllImport("user32.dll")]
        private static extern void mouse_event(UInt32 dwFlags, UInt32 dx, UInt32 dy, 

        UInt32 dwData, IntPtr dwExtraInfo);
        

        [DllImport("user32.dll")]
        static extern bool SetCursorPos(int x, int y);
        
        private const UInt32 MouseEventLeftDown = 0x0002;
        private const UInt32 MouseEventLeftUp = 0x0004;
        private const UInt32 MouseEventRightDown = 0x0008;
        private const UInt32 MouseEventRightUp = 0x0010;

        static public int konumX
        {
            get { return System.Windows.Forms.Control.MousePosition.X; }
        }

        static public int konumY
        {
            get { return System.Windows.Forms.Control.MousePosition.Y; }
        }


        public static void SendLeftClick()
        {
            mouse_event(MouseEventLeftDown, (uint)konumX, (uint)konumY, 0, new System.IntPtr());
            mouse_event(MouseEventLeftUp, (uint)konumX, (uint)konumY, 0, new System.IntPtr());
        }

        public static void SendRightClick()
        {
            mouse_event(MouseEventRightDown, (uint)konumX, (uint)konumY, 0, new System.IntPtr());
            mouse_event(MouseEventRightUp, (uint)konumX, (uint)konumY, 0, new System.IntPtr());
        }

        public static void SendMouseDown()
        {
            mouse_event(MouseEventLeftDown, (uint)konumX, (uint)konumY, 0, new System.IntPtr());
        }

        static public void SetFare(int x, int y)
        {
            SetCursorPos(x,y);
        }
    }
