c# - “检测到无法访问的代码”我已经查看了其他无法访问的代码，但我似乎无法修复我的，halp

Question

我正在为学校做一个 tictactoe 项目，我似乎无法解决无法访问的代码问题。我已经查找了其他无法访问的代码问题，但我不确定如何解决它，因为我不太擅长这个。我知道这是一个警告，但是当我启动我的程序时，它不会在我按下 em 时填充空白。

    private void Movement(object sender, EventArgs e)
    {
        if (InvokeRequired)
        {
            this.Invoke(new Action<object, EventArgs>(Movement), new object[] { sender, e });
            return;
            UpdateData(sender); //This is where it points for unreachable
            var lbl = (Label)sender;
            lbl.Enabled = false;
            lbl.Text = currentPlayer.ToString();
            if (!CheckWin())
                NextTurn();

        }
    }
    private void UpdateData(object sender)
        {
            Label lbl = sender as Label;
            if (lbl == lbl00)
                GameData[0, 0] = currentPlayer;
            else if (lbl == lbl10)
                GameData[1, 0] = currentPlayer;
            else if (lbl == lbl20)
                GameData[2, 0] = currentPlayer;
            else if (lbl == lbl01)
                GameData[0,1] = currentPlayer;
            else if (lbl == lbl11)
                GameData[1, 1] = currentPlayer;
            else if (lbl == lbl21)
                GameData[2, 1] = currentPlayer;
            else if (lbl == lbl02)
                GameData[0, 2] = currentPlayer;
            else if (lbl == lbl12)
                GameData[1, 2] = currentPlayer;
            else if (lbl == lbl22)
                GameData[2, 2] = currentPlayer;
        }

因为你放了一个return在 this.Invoke(new Action<object, EventArgs>(Movement), new object[] { sender, e }); 之后线路所以其他线路无法到达
