Mongo C# JSON reader was expecting a value but found 'replSetGetStatus'

Question

I was unable to find the proper way to call shell command from Mongo C# driver version 2.7.2

  public async Task RsStatus()
  {
     var res = await _admin.RunCommandAsync<object>("replSetGetStatus");
  }

Gives me an the error :

  JSON reader was expecting a value but found 'replSetGetStatus'

I'm guessing this simply not the way to call shell methods. Can any one supply me with an example ?

Thanks in advance.

db.adminCommand function expects and object to be passed as a parameter (here) so you can take advantage of BsonDocumentCommand generic type and also get a result as a BsonDocument, try:

var command = new BsonDocumentCommand<BsonDocument>(
                    new BsonDocument() { { "replSetGetStatus", 1 } });

var res = await _admin.RunCommandAsync<BsonDocument>(command);
