[Mono-list] Embeding Mono. Memory management

But how GC knows when to free such objects? When it frees such objects?
Could GC free the object when I still need it? 
for example

void func() {
  MonoString* str=mono_string_new (domain, "some text");
   could GC free str before "using str", if no, why?
  // using str
