无法解析符号 [英] cannot resolve symbol

问题描述

我制作了一个简单的表(将其称为志愿者)，但是当我想在我的代码中调用它时，Visual Studio无法识别它.错误是无法解析符号志愿者" .

i have made a simple table (lets call it volunteers), but when i want to call it in my code behind Visual studio can not recognize it. The error is cannot resolve symbol 'volunteers'.

下面是代码:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="root_VerifyUsers.aspx.cs" 
     MasterPageFile="~/Root.Master" %>

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

               <p>
                   <asp:Table runat="server" ID="volunteers" ForeColor="Green" Width="100%" Height="85%"  BorderColor="Red"></asp:Table>

                   <asp:TableHeaderCell ID="NationalId" runat="server">National Id</asp:TableHeaderCell>
                   <asp:TableHeaderCell ID="Email" runat="server">Email</asp:TableHeaderCell>
               </p>

</asp:Content>

在代码后面:

public partial class RootVerifyUsers : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {


        TableRow tr = new TableRow();
        TableCell fname = new TableCell();

        TableCell NationalId=new TableCell();
        tr.Cells.Add(NationalId);
        volunteers.Rows.add(tr);

    }

}
