Detailed Description

template<class TKey, class TValue>
class System::Collections::Concurrent::ConcurrentDictionary< TKey, TValue >

Thread-safe dictionary implementation. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

   #include <system/collections/concurrent/concurrent_dictionary.h>
   #include <system/smart_ptr.h>
  
   using namespace System;
   using namespace System::Collections::Generic;
  
   int main()
   {
     const int itemsCount = 32;
  
     // Create the ConcurrentDictionary-class instance.
     auto concurrentDictionary = MakeObject<ConcurrentDictionary<int, int>>();
  
     // Fill the concurrent dictionary.
     for (auto i = 0; i < itemsCount; ++i)
     {
       concurrentDictionary->Add(i, i * i);
     }
  
     Console::WriteLine(concurrentDictionary->idx_get(3));
  
     return 0;
   }
   /*
*  This code example produces the following output:
*  9
   */

Template Parameters

TKey	Key type.
TValue	Value type.
