如何建立与远程数据库sql server的连接？

如何解决如何建立与远程数据库sql server的连接？

当尝试使用 enable-migrations 连接到远程数据库时，我得到一个错误，该错误坚持要求检查连接字符串，我要做的就是将我的上下文连接到远程数据库以提供并用“迁移”映射“用户”类，这是连接字符串：

<add name="TransformerANDConnectDB" connectionString="data source=REMOTE_SERVER_xx ;initial catalog=TransformerANDConnectDB;user id=xxx ;password=xxx ;Integrated Security=True ;MultipleActiveResultSets=True;"  providerName="System.Data.sqlClient" />

否则，我向您介绍启用迁移后发生的错误：

 ---> System.Data.sqlClient.sqlException: Échec de l'ouverture de session de l'utilisateur 'ADSLOCAL\G558253'.
  à  System.Data.sqlClient.sqlInternalConnectionTds..ctor(DbConnectionPoolIdentity identity,sqlConnectionString connectionoptions,sqlCredential credential,Object providerInfo,String newPassword,securestring newSecurePassword,Boolean redirectedUserInstance,sqlConnectionString 
访问数据库时发生错误。这通常意味着与数据库的连接失败。检查连接字符串是否正确，是否使用了适当的DbContext构造函数来指定它或在应用程序的配置文件中找到它。有关DbContext和连接的信息，请参见http://go.microsoft.com/fwlink/?LinkId=386386。有关失败的详细信息，请参见内部异常。

这是我的上下文文件：

public class TransformerConnectMEContext  :DbContext 
{
    public TransformerConnectMEContext()
            : base("Name=TransformerANDConnectDB")
    {
        Database.Setinitializer<TransformerConnectMEContext>(new TransformerConnectMEContextinitializer());
    }
    public DbSet<User> Users { get; set; }
}

内部例外：

解决方法

在连接字符串中，将Integrated Security设置为false。

将Integrated Security设置为false时，将在连接中指定用户ID和密码。设置为true时，将使用当前的Windows帐户凭据进行身份验证
