asp.net无法检索元数据 [英] asp.net unable to retrieve metadata

问题描述

您好，我有一个问题，MVC的控制器，即使在阅读提示后。
在DbContext上添加一个构造函数，删除无效的，改变providerName =System.Data.SqlClient等等。

hi i am having a issue with MVC to make a controller even after reading the tips. adding a constructor on the DbContext, deleting the non worked, changing providerName="System.Data.SqlClient" and so on.

我的模型类看起来像这个：

my model class look like this:

public class RecruiterModel
{
    public string CompanyName { get; set; }
    public string Website { get; set; }
    public string CompanySize { get; set; }
    public string LinkedInCompanyURL { get; set; }
    public string LinkedInID { get; set; }
    public string Specialities { get; set; }
    public string Category { get; set; }
    public string Location { get; set; }
    public int ContactPhone { get; set; }
    public string ContactEmail { get; set; }
}

public class RecruiterDBContext : DbContext
{

    public DbSet<RecruiterModel> Recruiters { get; set; }
}

并且我的web.config connectionStrings如下所示：

and my web.config connectionStrings looks like this:

<add name="ApplicationServices"
     connectionString="data source=.\SQLEXPRESS;Integrated  Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
     providerName="System.Data.SqlClient" />
<add name="RecruiterDBContext"
     connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Recruiters.mdf;Integrated Security=True"
     providerName="System.Data.SqlClient"
/>

任何提示？

推荐答案

我找到了创建控制器类的解决方案：
在模型类上，我添加了

I have found the solution to create the controller class: On the model class i added the

使用System.ComponentModel.DataAnnotations ;

using System.ComponentModel.DataAnnotations;

public class RecruiterModel
{
[Key]
public string Id {get;组;

public class RecruiterModel { [Key] public string Id { get; set;

然后在web.config上注释掉整个

then on the web.config i commented out the whole

connectionStrings标记

connectionStrings tag

然后我创建了控制器，但它工作。

then i created the controller but and it worked.

虽然它的工作，但在解决方案资源管理器选项卡下的App_Data我看不到数据库文件... hmm另一个问题。

though it works but on the Solution Explorer tab under App_Data i do not see the db file... hmm another issue.
