Answer 1

仅使用一个习俗文本箱,用以阻挡或取代切割、复制、过去指挥:

public class MyTextBox : TextBox
{
    private const int WM_CUT   = 0x0300;
    private const int WM_COPY  = 0x0301;
    private const int WM_PASTE = 0x0302;

    protected override void WndProc(ref Message m)
    {
        switch(m.Msg)
        {
            case WM_CUT:
                // Handle Cut
                return;

            case WM_COPY:  
                // handle copy 
                return;

            case WM_PASTE:
                // handle paste
                return;
        }

        base.WndProc(ref m);
    }
}
