Question

我的代码块：

   public StudentsUnitOfWork()
        {
            var connectionString = ConfigurationManager.AppSettings["MongoDBConectionString"];
            var client = new MongoClient(connectionString);
            var server = client.GetServer();
            var databaseName = ConfigurationManager.AppSettings["MongoDBDatabaseName"];
            _database = server.GetDatabase(databaseName);
        }

VS 2015我得到client.GetServer() deprecated , how can I fixed it?

在我改为使用之后：

public StudentsUnitOfWork()
        {
            var connectionString = ConfigurationManager.AppSettings["MongoDBConectionString"];
            var client = new MongoClient(connectionString);
           // var server = client.GetServer();
            var databaseName = ConfigurationManager.AppSettings["MongoDBDatabaseName"];
            _database = client.GetDatabase(databaseName);
        }

它说，不能隐式转换类型..

这是我的整个背景，对我来说效果很好：

public class MyContext
{
    public const string COLLECTION_NAME = "CollectionName";

    private static readonly IMongoClient _client;
    private static readonly IMongoDatabase _database;
    static MyContext()
    {
        var connectionString = ConfigurationManager.AppSettings["MongoDBConectionString"];
        _client = new MongoClient(connectionString);
        var databaseName = ConfigurationManager.AppSettings["MongoDBDatabaseName"];
        _database = _client.GetDatabase(databaseName);
    }

    public IMongoClient Client
    {
        get { return _client; }
    }

    public IMongoCollection<TDocument> DocumentType =>
        _database.GetCollection<TDocument>(COLLECTION_NAME);
}

client.GetServer（）已弃用，我该如何修复它？
