entity framework：无法加载指定的元数据资源

我决定将Entity Connection String从app.config移动到代码。 但是在设置之后如下：

  public static string GetConnectionString() { string connection = ""; SqlConnectionStringBuilder sqlBuilder = new SqlConnectionStringBuilder(); sqlBuilder.DataSource = dbServer; sqlBuilder.InitialCatalog = dbInitialCatalog; sqlBuilder.IntegratedSecurity = false; sqlBuilder.UserID = dbUserName; sqlBuilder.Password = dbPasswWord; sqlBuilder.MultipleActiveResultSets = true; EntityConnectionStringBuilder entity = new EntityConnectionStringBuilder(); // entity.Name = "EntityBazaCRM"; entity.Metadata = @"res://*/Data.System.csdl|res://*/Data.System.ssdl|res://*/Data.System.msl"; entity.Provider = "System.Data.SqlClient"; entity.ProviderConnectionString = sqlBuilder.ToString(); connection = entity.ToString(); return connection; } 

我抛出exceptionUnable to load the specified metadata resource. 在.Designer.cs中。

  /// 
 /// Initialize a new EntityBazaCRM object. /// 
 public EntityBazaCRM(string connectionString) : base(connectionString, "EntityBazaCRM") { this.ContextOptions.LazyLoadingEnabled = true; OnContextCreated(); } 

如果我在我的Entity创建者中定义.Name，则会抛出另一个exception

"Other keywords are not allowed when the 'Name' keyword is specified." (System.ArgumentException) Exception Message = "Other keywords are not allowed when the 'Name' keyword is specified.", Exception Type = "System.ArgumentException"

我知道我遗漏了一些我必须改变的东西，以便自生成的代码使用新的连接字符串，但在哪里寻找它？

看完这篇答案文章和这篇博客后，我改变了：

  entity.Metadata = @"res://*/Data.System.csdl|res://*/Data.System.ssdl|res://*/Data.System.msl"; 

至：

  entity.Metadata = "res://*/"; 

它的工作原理:-)
