memcmp() - C# / C Sharp

Hi,

Does anyone know the c#-function of c++'s memcmp()?

Mads,

There is no such function. memcmp compares two pointers in memory to
see if the referenced bytes are the same. This can't be done in C# because
you can not guarantee that a location in memory will always have the same
contents (because of memory management).

However, if you have two byte arrays, you could easily write a routine
that will cycle through the arrays and compare the bytes.

Hope this helps.

If you have an IntPtr either via fixing the memory via the "fixed" verb
or via the GCHandle.AddrOfPinnedObject() method you can then populate it
via the Marshal.Copy() method.
