Question

I have the following class in C++/CLI and an explicit template instantiation for the int primitive..

template<typename T> public ref class Number {     T _value; public:     static property T MinValue     {         T get()         {             return T::MinValue;         }     }      static property T MaxValue     {         T get()         {             return T::MaxValue;         }     }      property T Value     {         T get()         {             return _value;         }          void set(T value)         {             if( value<MinValue || value > MaxValue)                 throw gcnew System::ArgumentException('Value out of range');              _value = value;         }     }  };  template ref class Number<int>; 

On compiling this and inspecting the generated assembly using reflector I am able to see a class called Number<int> but while trying to instantiate this same class in C# the compiler complains about some System::Number class not taking a template argument. What am I doing wrong? Can this be done at all?

Answer 1

I have a work around, declare an additional class inheriting the Number<int> class. This class is now visible in C# and can be instantiated.

public ref class MyInt32 : public Number<int> { };
