Question

I have an System::IO::MemoryStream which is added to from an FTP client. How do I retrieve the last N bytes of it?

Answer 1

Use the Seek method with SeekOrigin::End to specify an offset from the end of the stream, then read your data.

int n = ...;
Stream^ s = ...;

s->Seek(-n, SeekOrigin::End); // minus n because we want n bytes back from the end.
array<Byte>^ data = gcnew array<Byte>(n);
s->Read(data, 0, n);
