用DATALIST实现了随机出题，如果要计算得分应该怎么来写代码

[f80122]

我用DATALIST实现了随机出题，如果要计算得分应该怎么来写代码？本人对ASP了解不多，希望有高人指点下。附单选题代码

<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<%#(Container .ItemIndex +1) %>.
QusetionTYPE:
<asp:Label ID="QusetionTYPELabel" runat="server"
Text='<%# Eval("QusetionTYPE") %>' />
<br />
QuestionSUBJECT:
<asp:Label ID="QuestionSUBJECTLabel" runat="server"
Text='<%# Eval("QuestionSUBJECT") %>' />
<br />
A:
<asp:RadioButton ID="rdoA" runat="server" Text='<%# Eval("A") %>' GroupName ="S1">
</asp:RadioButton>
<br />
B:
<asp:RadioButton ID="rdoB" runat="server" Text='<%# Eval("B") %>' GroupName ="S1">
</asp:RadioButton>
<br />
C:
<asp:RadioButton ID="rdoC" runat="server" Text='<%# Eval("C") %>' GroupName ="S1">
</asp:RadioButton>
<br />
D:
