Bitconverter toint16 c#
WebAug 22, 2015 · By removing .As () and replacing with (T) (object), and replacing all the BitConverter work with bitwise work, we cut our work down to: 69% original time for byte. 73% original time for short. 80% original time for int. 90% original time for long. Also note that we returned the exact same values for all situations.
