您可以帮忙吗?

推荐答案

using Microsoft.DirectX.DirectInput;

Device mouse;

void Initialize()
{

            mouse = new Device(SystemGuid.Mouse);
            mouse.SetCooperativeLevel(this,CooperativeLevelFlags.NonExclusive |CooperativeLevelFlags.Background );
            mouse.Acquire();
}

void RefreshMouse()
        {
//Call this method from some timer

            MouseState state = mouse.CurrentMouseState;
//Do something with it....
//Note: You get position of mouse from some reference and is of no use
//What is possible then? You can capture mouse button state and use native System.Windows.Forms.Cursor.Position to get the position of mouse
//To check Click on a panel use
if (state.GetMouseButtons()[0]!=0&& VideoPanel.Bounds.Contains(Cursor.Position))
                {
                    Media.FullScreen();
                }
}
