c# - 如何在 C# 中禁用鼠标单击

Question

努力实现

我试图在一段时间内阻止鼠标输入

我想使用这样的代码:-

BlockMouse(true);

// My code starts here
...
// My code ends here

BlockMouse(false);

我试过了

• BlockInput(true) 但它需要更高的权限

使用此代码并实现 IMessageFilter

Rectangle BoundRect;
Rectangle OldRect = Rectangle.Empty;

private void EnableMouse()
{
    Cursor.Clip = OldRect;
    Cursor.Show();
    Application.RemoveMessageFilter(this);
}
public bool PreFilterMessage(ref Message m)
{
    if (m.Msg == 0x201 || m.Msg == 0x202 || m.Msg == 0x203) return true;
    if (m.Msg == 0x204 || m.Msg == 0x205 || m.Msg == 0x206) return true;
    return false;
}
private void DisableMouse()
{
    OldRect = Cursor.Clip;
    // Arbitrary location.
    BoundRect = new Rectangle(50, 50, 1, 1); 
    Cursor.Clip = BoundRect;
    Cursor.Hide();
    Application.AddMessageFilter(this);
}
