Good night

I'm trying to convert a CString into a System::String on a MFC project,
this way:

CString t1("Hello, World!");

#pragma push_macro("new")
#undef new
System::String *s1 = new System::String(t1);
#pragma pop_macro("new")

Everything works ok, but if I try to free s1

delete s1;

an error occurs.
error C3841: illegal delete expression: managed type 'System::String'
does not have a destructor defined

Shouldn't I delete s1? How's responsible for that?
If I'm the responsible, how do I free s1?

Thanks in advance and Merry Xmas to all

Hi,

You don't have to free the String. The garbage collector will do that for
you, once it detects that noone is using it anymore. I.e. all managed
pointers to it are out of scope, and it is not pinned.
