You need to be very careful here. Delphi strings are reference counted; the refcount of s in DelphiFunction will be zero at the end of the function, so the memory that is used by s will be returned to the memory allocator, and potentially be used (and overwritten) by something else after DelphiFunction returns before the C# caller can fetch the content. When that happens, all sorts of havoc will occur. In a multi-threaded situation (especially on multi-core systems) that can be really soon.

See stackoverflow.com/faq (You may answer your own question) and here: meta.stackexchange.com/questions/12513/… | |
