C# 如何在按下 w、s、a、d 按钮时删除“叮”系统声音

Question

First of all i can not use

KeyEventArgs.SuppressKeyPress

Because i am using Key_Down event to listen to input from the user,essentially i am making a Pacman game and when the user presses W or S or A or D there is a 'ding' sound that windows makes.I want to disable it but i do not know how. My Key_Down method:

if (e.KeyCode == Keys.A) //A press moves left
        {
            k = 1;
            left = true;
            right = false;
            up = false;
            down = false;
        }
        else if(e.KeyCode == Keys.D) //D press moves right
        {
            k = 3;
            left = false;
            right = true;
            up = false;
            down = false;
        }
        else if(e.KeyCode == Keys.S)
        {
            k = 2;
            left = false;
            right = false;
            up = false;
            down = true;
        }
        else if(e.KeyCode == Keys.W)
        {
            k = 4;
            left = false;
            right = false;
            up = true;
            down = false;
        }

My form uses buttons that i disable when the user presses the 'Start' Button. i use:

Button.Disable = true; is it perhaps caused by the buttons still listening for user input or what? I also have some labels and a Listbox,do i need to disable them too?

如果您使用的是 .NET 框架，那么在您处理之后添加这行代码：

        e.SuppressKeyPress = true;
