Visual C++ .NET/Collections/KeyValuePair

Use the KeyValuePair generic class when using the for each statement

 
#include "stdafx.h"
using namespace System;
using namespace System::Collections::Generic;
int main()
{
   IDictionary<String^, String^>^ dict;
   dict = gcnew Dictionary<String^, String^>();

   dict->Add("a", "A");
   dict->Add("o", "B");
   dict->Add("i", "C");

   for each (KeyValuePair<String^, String^>^ pair in dict)
   {
      Console::WriteLine(" {0}: {1}", pair->Key, pair->Value);
   }
   dict->Remove("hat");

   for each (KeyValuePair<String^, String^>^ pair in dict)
   {
      Console::WriteLine(" {0}: {1}", pair->Key, pair->Value);
   }
}
