Use this code and implement IMessageFilter aswell

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);
}

I think it is more elegant to set all your controls (like button) to disabled for the time your code is running and then enable them again

To give the user an optical feedback set the cursor to busy with Application.UseWaitCursor = true; and then Application.UseWaitCursor = false;

of course this solution only blocks the mouse clicks on your application and does not disable the mouse clicks completely

我认为阻止鼠标点击不是很好，因为大多数输入都是通过鼠标点击，如果你重写protected override void OnMouseDown(MouseEventArgs e)更好
