You can simply use the same way you would in C. Cast your buffer to a
pointer and do pointer arithmetic with it.

Simple example:

void main ()
{
        char[] testbuffer = new char [8] { 0, 1, 2, 3, 4, 5, 6, 7 };
        char* testbufferoffset = ((char*)testbuffer) + 5;
        assert (testbufferoffset[0] == 5);
        testbufferoffset[1] = 25;
        assert (testbuffer[6] == 25);
}
