Which will be faster?

Hi There

I am new to c#. I am using SqlDataReader to read database records(using c#).I have found lots of way to do it,but for performance i have found that ordinal reading is fast. Now I want to read a guid field ,as we know that with ordinal reading we can do this in two way
1)reader.GetGuid(0)
2) (Guid)reader[0]

but I don't know which will be faster...
