How to pass Generic::List^ to function in CLI/C++ ?

Question

Hello,

how can I pass generic list to a function? Example below does NOT work properly.

 

   15 public ref class A

   16 {

   17 public:

   19 

   20   A{}

   21   {

   22   }

   23   ~A{}

   24   {

   25   }

   26 

   27 private: System::Void use( System::Collections::Generic::List^ list ){

   28 

   29            // working with generic list "genericList" from class B

   30 

   31          }//

   32 

   33 }; // public ref class A

   34 

   35 public ref class B

   36 {

   37 public:

   38   List<Object^>^ genericList;

   39 

   40   B{}

   41   {

   42    genericList = gcnew List<Object^>();

   43   }

   44   ~B{}

   45   {

   46    delete( genericList );

   47   }

   48 

   49 private: System::Void button1_Click(){

   50 

   51          genericList->Add( ... );

   52 

   53          A a = gcnew A();

   54          A->use( genericList ); // ERROR C2664

   55 

   56          delete( a )

   57 

   58          }//

   59 

   60 }; // public ref class B

 

many thanks.

 

Answer 1

You need to specify the generic type for the method, ie: List<Object^>^

 

private: System::Void use( System::Collections::Generic::List<Object^>^ list )
