Question

您好我想知道是否有任何简化以下IF声明的方法。我有47个问题要经历，我真的不想让这个重复。我不熟悉c＃而且想要一只手。

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，为什么不直接使用RadioButtonList的SelectedIndex

e.g。

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

Answer 2

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

Answer 3

如果您想为所选项目分配不同的值，这种方法将变得简单：

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

假设您拥有表

中的所有单选按钮

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

以下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;

        }
    }
}

}
