求助！！：Asp.net如何传递值？？

Question

我在ASp.net前台Source里面添加了一个GridView，代码如下：

  <asp:GridView ID="GridView2" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" CssClass="MyLine" DataKeyNames="OrderID" GridLines="None" Height="100%" HorizontalAlign="Center" OnPageIndexChanging="gvOrderList2_PageIndexChanging" OnRowDataBound="GridView2_RowDataBound" PageSize="12" Width="100%">
<Columns>
<asp:BoundField HeaderText="序号" ReadOnly="True">
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:BoundField DataField="courseID" HeaderText="课程ID" ReadOnly="True">
                <ItemStyle HorizontalAlign="Center" />
                <HeaderStyle HorizontalAlign="Center" />
                </asp:BoundField>
<asp:BoundField DataField="teacherID" HeaderText="教师ID" ReadOnly="True">
                <ItemStyle HorizontalAlign="Center" />
                <HeaderStyle HorizontalAlign="Center" />
                </asp:BoundField>
<asp:BoundField DataField="teacherName" HeaderText="教师姓名" ReadOnly="True">
                <ItemStyle HorizontalAlign="Center" />
                <HeaderStyle HorizontalAlign="Center" />
                </asp:BoundField>
<asp:BoundField DataField="studentID" HeaderText="评价学生ID" ReadOnly="True">
                <ItemStyle HorizontalAlign="Center" />
                <HeaderStyle HorizontalAlign="Center" />
                </asp:BoundField>
<asp:BoundField DataField="studentName" HeaderText="评价学生姓名" ReadOnly="True">
                <ItemStyle HorizontalAlign="Center" />
                <HeaderStyle HorizontalAlign="Center" />
                </asp:BoundField>
                <asp:TemplateField>
                    <HeaderStyle HorizontalAlign="Center" />
                    <ItemStyle HorizontalAlign="Center" />
                    <ItemTemplate>
<asp:LinkButton ID="lnkbtnGoPay" runat="server" CommandArgument='<%#Eval("courseID") %>' OnClick="lnkbtnGoPay_OnClick" OnCommand="lnkbtnGoPay_Command">去查看</asp:LinkButton>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

其中Linkbutton的lnkbtnGoPay_Command事件后台代码如下：

 protected void lnkbtnGoPay_Command(object sender, CommandEventArgs e)
    {
        Response.Redirect("EvaluateTeacherDetail.aspx?courseID=" + e.CommandArgument);
    }

问题：我如何在lnkbtnGoPay_Command事件中同时传递courseID和studentID?
形如： Response.Redirect("EvaluateTeacherDetail.aspx?courseID=" + e.CommandArgument+"&studentID="+????????????);这里？处该怎么写呢？？

Answer 1

 <%#Eval("courseID")+"|"+Eval("studentID") %>

string[] arr = e.CommandArgument.Split('|');
Response.Redirect("EvaluateTeacherDetail.aspx?courseID=" +arr[0] + "&studentID=" + arr[1];
