Detailed Description

template<typename Dict>
class System::Collections::Generic::_KeyCollection< Dict >

Collection of Dictionary's keys. References collection, doesn't copy anything. 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.

Parameters
DictDictionary type.
