IS it possible to get JSON (as string) for mongo from C# in code.
Visual Studio Watch show's the string, but how to get it in code I can't understand.

^var aggregate = procuraCollection.Aggregate(new AggregateOptions()

{ AllowDiskUse = true, UseCursor = true }

);
var dd2 = Builders<BsonDocument>.Filter.Eq("RepositoryId", this.repositoryId);
aggregate = aggregate.Match(dd2);
var json= ?????;^
