Unreachable code detected in case statement

Question

I have a code:

    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        switch (keyData)
        {
            case Keys.Alt|Ke         


        

Answer 1

According to your code, all the break(s) and the last statement are never reached, for there are the return statements before.

You could rewrite your code like this:

    switch (keyData)
    {
        case Keys.Alt|Keys.D1:
            if (this._condition1) return true;
            else goto default;

        case Keys.Control |Keys.U:
            if (this._condition2) return true;
            else goto default;

        default:
            return base.ProcessCmdKey(ref msg, keyData);
    }
