Generics in C# look inferior to templates (especially to concepts) in C++,
however now and then you can build a wonderful pieces the way a C++ profi would
Consider a generic converter method: T Convert<T>(object value).
T Convert<T>(object value)
In C++ I would create several template specializations for all supported
conversions. Well, to make things harder, think of converter provider supporting
public interface IConverterProvider
Converter<object, T> Get<T>();
That begins to be a puzzle in C++, but C# handles it easily!
My first C#'s implementation was too naive, and spent too many cycles in
provider, resolving which converter to use. So, I went on, and have created a
sofisticated implementation like this:
private IConverterProvider provider = ...
public T Convert<T>(object value)
var converter = provider.Get<T>();
public class ConverterProvider: IConverterProvider
public Converter<object, T> Get<T>()
private static class Impl<T>
// Heavy implementation initializing converters.
converter = ...
public static readonly Converter<object, T> converter;
Go, and do something close in C++!
