Hi guys, I have a problem with fileInfo struct
the following code works fine but I think it s not correct to use keywork
new for a struct
In C#, structs are not what you'd expect (just plain structured data).
Contrary to C/C++, they are objects, too. But just like in C/C++, they
/can/ be used as value types. So, instantiating a C# struct with new is
perfectly valid, but maybe not necessary. If you just declare a variable
of a struct type, you will get a locally (i.e. stack)-allocated struct.
Be aware that when you allocate a struct locally, there won't be any
constructor invocation so the fields are uninitialized, probably
containing random garbage.
fileInfo informazioni_file=new fileInfo() ;
if (!file_valido(file,ref informazioni_file ))
How should I write it?
probably, the following would work as well:
| fileInfo informazioni_file;
| if (!file_valido(file,ref informazioni_file ))
(no need to initialize the fileInfo struct when file_valido() will write
to it)
