Detailed Description

template<typename T>
class System::Collections::Generic::ICollection< T >

Interface of collection of elements. 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
TStored type.
