C＃TypeInitializationException在自動生成的代碼

我保存在我的數據庫中的對象（實體），這樣是未處理，在我的愚見。這是類扔：C＃TypeInitializationException在自動生成的代碼

//------------------------------------------------------------------------------

//  This code was generated from a template.

//  Manual changes to this file will be overwritten if the code is regenerated.

//------------------------------------------------------------------------------ 

namespace WindowsFormsApplication1 
{ 
    using System; 
    using System.Data.Entity; 
    using System.Data.Entity.Infrastructure; 

    public partial class UserEntities : DbContext 
    { 
     public UserEntities() 
      : base("name=UserEntities") //OBS: THIS LINE THAT THROWS THE EXCEPTION 
     { 
     } 

     protected override void OnModelCreating(DbModelBuilder modelBuilder) 
     { 
      throw new UnintentionalCodeFirstException(); 
     } 

     public virtual DbSet<Users> Users { get; set; } 
    } 
}

異常只是說：

An unhandled exception of type 'System.TypeInitializationException' occurred in EntityFramework.dll 

Additional information: Se produjo una excepción en el inicializador de tipo de 'System.Data.Entity.Internal.AppConfig'.

我一直在調查了沒有成功小時，任何暗示？在此先感謝

UPDATE：app.config文件：

在配置文件（app.config）中有一些問題。在這裏看到類似的異常（認爲你的問題可能會不同） - http://stackoverflow.com/q/17585611/5311735 – Evk

謝謝，但是當我沒有觸及代碼時，這可能嗎？ –

您的配置文件沒有連接字符串，或者連接字符串的格式不正確。另外，請檢查'InnerException'或其他異常的屬性，他們應該告訴你潛在的問題。 –

我發現有某種2分的DB具有相同名稱之間的衝突。在APP.CONFIG中對這些行進行評論的確有訣竅：

<!-- 
<add name="HerculesDatabaseEntities" connectionString="metadata=res://*/csdl|res://*/ssdl|res://*/msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=(LocalDB)\MSSQLLocalDB;attachdbfilename=|DataDirectory|\HerculesDatabase.mdf;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /> 
    <add name="userEntities" connectionString="metadata=res://*/UsersModel.csdl|res://*/UsersModel.ssdl|res://*/UsersModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=(LocalDB)\MSSQLLocalDB;attachdbfilename=|DataDirectory|\HerculesDatabase.mdf;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
