Question on converting char* into System.String

There are two ways to convert a char* received from the unmanaged code
into a managed System.String object that I am aware of. The first one
is to simply construct String object passing char* as constructor
parameter. The second one is to use Marshal::PtrToStringAnsi (or
similar) method. Both seem to work just fine. Are there any catches
that I am missing?

Thanks,

The most notable difference is that the String constructor takes a
real pointer and therefore requires you to compile with /unsafe to use
it from C#. PtrToStringAnsi takes an IntPtr so it can be used in
"safe" code.

Very good point Mattias, my bad. The reason being that
dotnet.languages.vc group does not seem very popular. Besided, I was
under the impression that the question I was asking was dotnet
specific rather than language specific.
