c# Repeater中CommandArgument传多个参数

<ItemTemplate>

  <asp:LinkButton ID="LinkButton1" CommandName="del" CommandArgument='<%# eval("Parent_Id")+","+eval("Id")  %>'  runat="server">删除</asp:LinkButton></div>
</ItemTemplate>


后台代码：

protected void GVSecondType_RowCommand(object sender, GridViewCommandEventArgse)
    {
        string cmdName = e.CommandName;
        if (cmdName == "del")
        {
            string[] estr = e.CommandArgument.ToString().Split(',');

            int Parent_Id = Convert.ToInt32(estr[0]);
            int TypeId = Convert.ToInt32(estr[1]);
         }
   
    }
