memcpy in C#

[Sidney Zhang]

Hi:
We need to manipulate data block in C#, is there anything in C# similiar as
memcpy/memset in C++?
copy bytes one by one is really a night mare for me.

Thanks
Sidney

(Actually memcpy/memset are usually libc or compiler-lib functions)

Try timing System.Array.Copy, I would expect it to have (at least
mildly) optimized code for value-type arrays.

How much does it slow your application down, compared to your
expectation and to a C-like implementation?

try Buffer.Copy(). it is faster than Array.Copy()
