简化单选按钮列表中的 if 语句

Question

嗨，我想知道是否有任何方法可以简化以下IF语句。我有47个问题要回答，我真的不想一直重复这个问题。我不熟悉 c#，想要帮忙。

protected void GA_Total(object sender, EventArgs e)
{
    // Generalized Anxiety Total 
    int GATotal = 0;
    Label1.Text = Convert.ToString(GATotal);
    //-----------Question 1----------------
    if (RadioButtonList.Items[0].Selected)
    {
        GATotal = GATotal + 0;
    }
    if (RadioButtonList.Items[1].Selected)
    {
        GATotal = GATotal + 1;
    }
    if (RadioButtonList.Items[2].Selected)
    {
        GATotal = GATotal + 2;
    }
    if (RadioButtonList.Items[3].Selected)
    {
        GATotal = GATotal + 3;
    }
    //-----------Question 13----------------
    if (RadioButtonList1.Items[0].Selected)
    {
        GATotal = GATotal + 0;
    }
    if (RadioButtonList1.Items[1].Selected)
    {
        GATotal = GATotal + 1;
    }
    if (RadioButtonList1.Items[2].Selected)
    {
        GATotal = GATotal + 2;
    }
    if (RadioButtonList1.Items[3].Selected)
    {
        GATotal = GATotal + 3;
    }
    //-----------Question 22----------------
    if (RadioButtonList2.Items[0].Selected)
    {
        GATotal = GATotal + 0;
    }
    if (RadioButtonList2.Items[1].Selected)
    {
        GATotal = GATotal + 1;
    }
    if (RadioButtonList2.Items[2].Selected)
    {
        GATotal = GATotal + 2;
    }
    if (RadioButtonList2.Items[3].Selected)
    {
        GATotal = GATotal + 3;
    }
    //-----------Question 27----------------
    if (RadioButtonList3.Items[0].Selected)
    {
        GATotal = GATotal + 0;
    }
    if (RadioButtonList3.Items[1].Selected)
    {
        GATotal = GATotal + 1;
    }
    if (RadioButtonList3.Items[2].Selected)
    {
        GATotal = GATotal + 2;
    }
    if (RadioButtonList3.Items[3].Selected)
    {
        GATotal = GATotal + 3;
    }
    //-----------Question 35----------------
    if (RadioButtonList4.Items[0].Selected)
    {
        GATotal = GATotal + 0;
    }
    if (RadioButtonList4.Items[1].Selected)
    {
        GATotal = GATotal + 1;
    }
    if (RadioButtonList4.Items[2].Selected)
    {
        GATotal = GATotal + 2;
    }
    if (RadioButtonList4.Items[3].Selected)
    {
        GATotal = GATotal + 3;
    }
    //-----------Question 37----------------
    if (RadioButtonList5.Items[0].Selected)
    {
        GATotal = GATotal + 0;
    }
    if (RadioButtonList5.Items[1].Selected)
    {
        GATotal = GATotal + 1;
    }
    if (RadioButtonList5.Items[2].Selected)
    {
        GATotal = GATotal + 2;
    }
    if (RadioButtonList5.Items[3].Selected)
    {
        GATotal = GATotal + 3;
    }
    //------------Results-------------------
    Label1.Text = Convert.ToString(GATotal);
}

Answer 1

您基本上是将项目的索引添加到GATOTAL中，为什么不直接使用RadioButtonList的SelectedIndex呢？

例如

GATotal += RadioButtonList.SelectedIndex + 
           RadioButtonList1.SelectedIndex + 
           RadioButtonList2.SelectedIndex +  
           RadioButtonList3.SelectedIndex + 
           RadioButtonList4.SelectedIndex + 
           RadioButtonList5.SelectedIndex;

Answer 2

GATotal += RadioButtonList.SelectedIndex + RadioButtonList1.SelectedIndex ...

Answer 3

如果要

为所选项目分配不同的值，此方法将变得容易：

protected void GA_Total(object sender, EventArgs e)
{
    // Generalized Anxiety Total 
    int GATotal = 0;
    GATotal += sumSelectedItems(radioButtonList);
    GATotal += sumSelectedItems(radioButtonList1);
    GATotal += sumSelectedItems(radioButtonList2);
    GATotal += sumSelectedItems(radioButtonList3);
    GATotal += sumSelectedItems(radioButtonList4);
    GATotal += sumSelectedItems(radioButtonList5);
    Label1.Text = GATotal.toString();
}

private int sumSelectedItems(RadioButtonList list)
{
    int sum = 0;
    for (int i = 0; i < list.Items.Count; i++)
    {
        if (list.Items[i].Selected)
        {
            sum += i;
        }
    }
    return sum;
}

Answer 4

假设您有表格中的所有单选按钮

<asp:Table ID="Table1" runat="server"><asp:RadioButtonList runat="server"></asp:RadioButtonList></asp:Table>

下面的代码适用于任意数量的单选按钮。

foreach (Control ctrl in Table1.Controls)
{
    if (ctrl is RadioButtonList)
    {  
    RadioButtonList rbl = (RadioButtonList)ctrl;
    for (int i = 0; i < rbl.Items.Count; i++)
    {
        if (rbl.Items[i].Selected)
        {
           GATotal+= RadioButtonList.SelectedIndex;
        }
    }
}

}
