Re: [ADVANCED-DOTNET] Complex (for me anyway) Marshalling

[Mattias Sjögren]

Simon,

PS It would be nice to be able to just get an IntPtr directly to the
string, which I believe is an optimization used by the Marshaler since it
is immutable, to save having to copy the string. Is this possible and what
could I do about ensuring it is pinned for the duration? Does anyone have
any insight on this?

Pin the string by allocating a GCHandle for it (GCHandleType.Pinned), then get the char pointer with GCHandle.AddrOfPinnedObject(). Keep it pinned during the call to unmanaged code.
