C# 使用随机值从另一个方法访问另一个变量

我已经创建了一个整数列表。我创建了一个从列表中选择一个随机数并使用文本框输出的方法。一旦在列表中选择了它，它将被删除，这样就不会重复。这是我的密码：

private void clickHandler(object sender, EventArgs e)
{
    if (btnCase.Text == "")
    {
        lblSelectedCase.Text = "Your Briefcase:";
        lblCasesToOpen.Visible = true;
        lblNumber.Visible = true;
        lblNumber.Text = myGame.counter.ToString();
        btnCase.Visible = true;
        btnCase.Text = ((Button)sender).Text;
        ((Button)sender).Visible = false;
    }
    else
    {
        lblNumber.Text = myGame.decreaseCounter().ToString();
        num = myGame.showAmount();

        var selected = MessageBox.Show("Briefcase amount: $" + num.ToString(), "", MessageBoxButtons.OK);

        if (selected == DialogResult.OK)
        {
            _label[num].Visible = false;
            myGame.removeAmount();
            ((Button)sender).Visible = false;
        }

        if(myGame.counter == 0)
        {
            foreach (Button button in this.Controls.OfType<Button>())
            {
                button.Enabled = false;
            }

            myGame.computeAverage();
            lblBankerOffer.Visible = true;
            lblOffer.Visible = true;
            lblOffer.Text = "$" + myGame.bankerOffer().ToString();
            btnDeal.Visible = true;
            btnNoDeal.Visible = true;
            lblCasesToOpen.Visible = false;
            lblNumber.Visible = false;
        }
    }
}

private void btnNoDeal_Click(object sender, EventArgs e)
{
    if (myGame.turn == 9)
    {
        int n = num;
        var winnings = MessageBox.Show("You won: $" + n.ToString(), "Congratulations", MessageBoxButtons.OK);

        if (winnings == DialogResult.OK)
        {
            if (n > myData.Score)
            {
                myData.Score = myGame.showAmount();
                myData.updateScore();
            }

            this.Hide();

            frmHome _frmHome = new frmHome(myData.User.ToString(), myData.FName.ToString(), myData.LName.ToString(), myData.Score);

            _frmHome.Closed += (s, args) => this.Close();
            _frmHome.Show();
        }
    }
    else
    {
        foreach (Button button in this.Controls.OfType<Button>())
        {
            button.Enabled = true;
        }

        lblNumber.Text = myGame.showCounter().ToString();
        lblBankerOffer.Visible = false;
        lblOffer.Visible = false;
        btnDeal.Visible = false;
        btnNoDeal.Visible = false;
        lblCasesToOpen.Visible = true;
        lblNumber.Visible = true;
    }
}

那么，当您调用这个`num=myGame.showAmount（）；`您是否已通过自己的代码。。？还有你的问题。。你该做什么不是一个问题question@MethodMan它将调用此方法public int showmount（）{index=_random.Next（0，amounts.Count）；返回amounts[index]；}。那么，当您在

}上设置断点时跨过它时，
amounts[index]
的值是多少
public int showAmount()
{
    index = _random.Next(0, amounts.Count);
    return amounts[index];
}
