Question

我有 ASP.NET MVC 应用程序，它在我的本地服务器上运行良好。当我将其部署到IIS（v7.0）中的 Windows Server 2008 Standard 时，应用程序正在运行属性（我可以看到要登录的面板），但是当我想要登录时，我有这样的错误。我还有页面联系人，当我想运行它时，我也有同样的错误我使用 ADO.NET实体数据模型添加Model.edmx。

代码很简单：

在控制器中：

private ImportEntities Entity = new ImportEntities();
public ActionResult Contact()
    {
        var dane = Entity.Contact.FirstOrDefault();
        return View("Contact",dane);
    }

Web.config中的连接字符串：

<add name="ImportEntities" connectionString="metadata=res://*/Models.Model.csdl|res://*/Models.Model.ssdl|res://*/Models.Model.msl;
 provider=System.Data.SqlClient;
 provider connection string=&quot;data source=AAA\aaa;
      initial catalog=Database_name;
      integrated security=True;
      MultipleActiveResultSets=True;
      App=EntityFramework&quot;"
 providerName="System.Data.EntityClient" />

错误：

我不明白：当我的应用程序与'''使用某些字符串连接的时刻在哪里？我无法安装任何其他程序在服务器上调试它并检查错误。

你有什么想法可以出错吗？

======
在Model.edmx中 - ＆gt; Model.tt - ＆gt; Contact.cs

namespace MyApp.Models
{
    using System;
    using System.Collections.Generic;

    public partial class Contact
    {
        public int id { get; set; }
        public string phone { get; set; }
        public string email { get; set; }
        public string address { get; set; }
        public string page { get; set; }
    }
}

======
我发现sql查询使用我的应用程序和@Paul_Zahra帮助。

SELECT TOP (1) 
[c].[id] AS [id], 
[c].[phone] AS [phone], 
[c].[mail] AS [mail], 
[c].[address] AS [address], 
[c].[page] AS [page]
FROM [dbo].[Contact] AS [c]

现在我可以看到第一行有问题。我记得我不应该（1），只需 1 。你知道如何改变吗？

Answer 1

这可能是由于您“共享”您的上下文...尝试此... ...（通常最好使用工作单元方法来创建和使用您的数据库上下文，除非您真的知道您在上下文中做了什么并且通常愿意微观管理它... ...

public ActionResult Contact()
{
    Contact dane = null;

    using (ImportEntities ctx = new ImportEntities())
    {
        ctx.Connection.Open();

        dane = ctx.Contact.FirstOrDefault()

        ctx.Connection.Close();
    }

    return View("Contact",dane);
}

修改：

您的问题可能源于DbProviderInfo.ProviderManifestToken; “标识正在使用的数据库服务器版本的字符串。例如，SQL Server提供程序对SQL Server 2008使用字符串”2008“。这不能为空，但可能为空。”

您的本地（工作正常）和SQL Server的服务器版本是否相同？我猜不是。

令牌在SSDL中指定。 See this post for some interesting insights into what is a pretty big problem with EF for some

你没有关闭那个＆＃34;

＆＃39;附近的语法不正确（＆＃39;。与实体框架的数据库连接
