我使用C#MongoDB.Driver库连接到MongoDB。一些有效的代码MongoClientclient=MongoClientBuilder.Build("77.199.99.90",27016,"admin","pwd");IReadOnlyListdbNames=this.client.GetDatabaseNamesAsync().Result;foreach(vardbnindbNames){IMongoDatabasemongoDb=client.GetDatabase(dbn);varcNames=mongoDb.GetCollectionNamesAsync().

当我使用FindOne时，它​​说“'MongoClientExtensions.GetServer(MongoClient)'isobsolete:'UsethenewAPIinstead.'Observer.Client”作为警告。这是我的代码collection.EnsureIndex(IndexKeys.Ascending("Username","Type"),IndexOptions.SetUnique(true));varuserlog=collection.FindOne(Query.Where(ul=>ul.Username==username&&ul.Type==ty
