如何保持得分？

Question

我正在做一个迷你测试，我不知道如何在用户提交测试后制作一个能够更新当前分数的跑分数。 分数可以波动25分，具体取决于问题是从错误到正确，反之亦然。

public partial class _Default : System.Web.UI.Page
{
private int totalScore = 0;

public void IncrementScore()
{
    totalScore += 25;
}

protected void Page_Load(object sender, EventArgs e)
{

    if (!IsPostBack)
    {
        lblHeader.Text = "quiz not taken";
    }
    else
    {
        lblHeader.Text = "Score: " + totalScore;
    }
}

protected void Submit_Click(object sender, EventArgs e)
{

    /***************************************************************************/
    if (IsValid)
        if (txtAnswer.Text.Equals("primary", StringComparison.InvariantCultureIgnoreCase))
        {
            lblQuestionResult1.ForeColor = System.Drawing.Color.Green;
            lblQuestionResult1.Text = "Correct";
        }
        else
        {
            lblQuestionResult1.ForeColor = System.Drawing.Color.Red;
            lblQuestionResult1.Text = "Incorrect";
        }

    /***************************************************************************/
    if (ddList.SelectedItem.Text.Equals("M:N"))
    {
        lblQuestionResult2.ForeColor = System.Drawing.Color.Green;
        lblQuestionResult2.Text = "Correct";
    }
    else
    {
        lblQuestionResult2.ForeColor = System.Drawing.Color.Red;
        lblQuestionResult2.Text = "Incorrect";
    }

    /***************************************************************************/
    if (RadioButton4.Checked == true)
    {
        lblQuestionResult3.ForeColor = System.Drawing.Color.Green;
        lblQuestionResult3.Text = "Correct";
    }
    else
    {
        lblQuestionResult3.ForeColor = System.Drawing.Color.Red;
        lblQuestionResult3.Text = "Incorrect";
    }

    /***************************************************************************/
    lblQuestionResult4.ForeColor = System.Drawing.Color.Red;
    lblQuestionResult4.Text = "Incorrect";
    if (Answer2.Checked && Answer3.Checked && !Answer1.Checked && !Answer4.Checked)
    {
        lblQuestionResult4.ForeColor = System.Drawing.Color.Green;
        lblQuestionResult4.Text = "Correct";
    }
}
}

Answer 1

递增的方法

private int totalScore = 0;

将无法正常工作，因为您为每个HTTP请求获取了一个新的_Default实例。

您可以在Session保持您的运行得分。

但是，我建议总是在需要时通过循环搜索答案并根据需要与每个答案相关联的分数来重新计算总分。 如果人们回去并改变答案（假设允许这样做），这简化了逻辑。

Answer 2

修改它看起来像看，检查语法，没有使用VS.

protected void Page_Load（object sender，EventArgs e）{

if (!IsPostBack)
{
    lblHeader.Text = "quiz not taken";
}
else
{
    Session["TotalScore"] = ""+totalScore; //Storing it in a session
    lblHeader.Text = "Score: " + Session["TotalScore"];
}

}

//增量方法

if(Session["TotalScore"]!=null)
 { 
  totalScore += 25;
 } 
else
{
totalScore=int.Parse(Session["TotalScore"])+25;
}
