C# 如何保持跑步成绩？

我正在做一个小测试，我不知道如何在用户提交测试后更新当前分数。根据问题从错误到正确的顺序，分数可以波动25分，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";
    }
}
}

递增法

private int totalScore = 0;

将不起作用，因为您会为每个HTTP请求获得一个新的

\u Default

实例

您可以在

但是，我建议在需要时，通过循环查看答案和与每个答案相关联的分数来重新计算总分。如果人们返回并更改答案（假设允许这样做），这将简化逻辑。
将其修改为类似“查看、检查语法”的内容，而不是使用VS

受保护的无效页面加载（对象发送方、事件参数e）
{

}

//增量法

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

public void IncrementScore（）{//second part here}如果您想让它更简单，只需在原始问题中将变量总分设置为static即可
if(Session["TotalScore"]!=null)
 { 
  totalScore += 25;
 } 
else
{
totalScore=int.Parse(Session["TotalScore"])+25;
}
