单独文件中的 C# 命名空间/类在查看时导致错误

标签 c# class namespaces using

我有两个项目“HOD”和“ Controller ”。 Controllers 是一个名为“Controllers”的类库。在 HOD 的代码文件中，我试图通过“使用 Controller ”来引用 Controller 命名空间。我在 HOD 项目中添加了一个对 Controllers 的引用，它确实显示在 VS2008 中的references 文件夹下。

当我构建项目时，我没有发现任何错误，但是当我查看页面时，我收到错误消息“找不到类型或命名空间名称‘ Controller ’(您是否缺少 using 指令或程序集引用？)” .

Controllers.cs(类库，Controllers 项目)

using System;
using System.Collections.Generic;
using System.Text;

namespace Controllers
{

    public class Controller {    }

}

index.aspx.cs(HOD 项目)
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Controllers;


public partial class HOD : Page
{

    string sop() { return "sop"; }

    protected void Page_Load(object sender, EventArgs e)
    {
        blahmsg.Text = sop();
    }

}

该项目位于我们的网络服务器上，Controllers.dll 与 HOD.dll 位于同一个 bin 文件夹中。在此先感谢您的帮助!

最佳答案

chelfers，感谢您在此处发布 sln 文件。根据它，您没有到位的项目引用。

您可以从 Visual Studio 添加它(删除引用、保存、添加引用)，或者您可以添加以下行:

ProjectReferences = "{E6A16990-5FC6-4FE3-8DAB-CD2FEC8CF4FF}|Controllers.dll;"

正下方
ProjectSection(WebsiteProperties) = preProject
    TargetFramework = "2.0"

(为了安全起见，请先复制 .sln 文件)。

PS:移动到 3.5，这是二十一世纪:)
