Question

See more:

ArrayList output = gcnew ArrayList();// as public declaration

this output should be accessed by the functions repeatedly like

function1();

int main(string^ args)
{
  function(string);
}

function1(string^ input)
{
  output->Add(string);
}

in VC++ 2008 \CLR console application
I received error code as c3145.

Refer to this table: http://connect.microsoft.com/VisualStudio/feedback/details/100163/c-cli-access-modifiers-are-not-consistent[^].

The difference between public and internal is this: public is visible from outside of declaring assembly (by any referencing assembly as well), internal visibility is limited by declaring assembly.

Your problem is quite different: error message c3145 reads: "'object' : global or static variable may not have managed type 'type'".

Why didn't you post the error message in first place? See http://msdn.microsoft.com/en-us/library/by40z94e.aspx[^].

You did not even show the line of code causing error message. Is it the first line in your code? It can be declared only inside ref class or structure. Move it into you class. See the help on error message again (above).

Right now, your code does not make sense though, because you're putting data nowhere, into the collection. Also, don't use ArrayList, use System::Collections::Generic::List. Non-generic collection classes are not needed anymore, after generic is introduced. Non-generic collection classes require type casting in members, who need it?

You can't declare .NET variables as global objects: it isn't supported: that's what the error is saying:

Error C3145 cannot declare a global or static managed type object or an _gc pointer

The problem is that .NET does not have a concept of global variables, only class scope. To get around this, you can declare it as a static member of a Globals class:

public ref class Globals
   {
   public:
      static ArrayList output = gcnew ArrayList();
   }

As usual, MSDN comes to the rescue: error C3145 global or static managed type object or an _gc pointer[^]
