I have been getting an issue with regards to the GetCurrentBsonType() method. 
I have looked around but the only fix I have come across is to skip the name as in the VerifyBsonType() method.

My situation for some context:

I read a value and then proceed to a custom serializer 
1) read start document
2) read string
3) get current type

Doing this results in an exception thrown by

if (_state != BsonReaderState.Value)
 {
 ThrowInvalidState("GetCurrentBsonType", BsonReaderState.Value);
 }

as _state is name.

However, if I change my operations to 

1) read start document
2) read string
3) read name
4) get current type

I get another exception when the value to be deserialized is in an array - where there is no name.

My proposed solution is to add

if(_state == BsonReaderState.Name)
 {
 SkipName();
 }

before the state check as in the VerifyBsonType() method.
