[解决办法]
首先在 DataList里面加入一个页眉按钮 代码如下 ，修改按钮的CommandName为submit这个名字
<FooterTemplate>
<asp:Button ID="Button1" runat="server" CommandName="submit" 
OnClick="submit_Click" Text="提交" />
</FooterTemplate>

然后在页面在 DataList 控件双击事件 ItemCommand
代码如：

C# code

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)        {            if (e.CommandName == "submit")            {                for (int i = 0; i <= e.Item.Controls.Count; i++)//根据你一个有多少个选项循环多少次                {                    RadioButton A = (RadioButton)DataList1.Items[i].FindControl("A");//第i选题第1个选项                    if (A.Checked)                     {                        Label Label1 = (Label)DataList1.Items[e.Item.ItemIndex].FindControl("Label1");                        string value = Label1.Text;                    }                    RadioButton B = (RadioButton)DataList1.Items[i].FindControl("B");//第i题第2个选项                    if (A.Checked)                     {                        Label Label2 = (Label)DataList1.Items[e.Item.ItemIndex].FindControl("Label2");                        string value = Label2.Text;                    }                    RadioButton C = (RadioButton)DataList1.Items[i].FindControl("C");//第i题第3个选项                    if (A.Checked)                     {                        Label Label3 = (Label)DataList1.Items[e.Item.ItemIndex].FindControl("Label3");                        string value = Label3.Text;                    }                    RadioButton D = (RadioButton)DataList1.Items[i].FindControl("D");//第i题第4个选项                    if (A.Checked)                     {                        Label Label4 = (Label)DataList1.Items[e.Item.ItemIndex].FindControl("Label4");                        string value = Label4.Text;                    }                }                            }
