Is there a less painful way to GetBytes for a buffer not starting at 0?

bytearray

I am having to deal with raw bites in a project and I need to basically do something like this

byte[] ToBytes(){
  byte[] buffer=new byte[somelength];
  byte[] tmp=new byte[2];
  tmp=BitConverter.GetBytes(SomeShort);
  buffer[0]=tmp[0];
  buffer[1]=tmp[1];
  tmp=BitConverter.GetBytes(SomeOtherShort);
  buffer[2]=tmp[0];
  buffer[3]=tmp[1];
}

I feel like this is so wrong yet I can't find any better way of doing it. Is there an easier way?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
