How do you determine whether a generic type argument is of a given type? This is what I have, but it seems hacky to instantiate the type just to test its type.

public void LogAllTheThings<T>()
    where T : class, new()
{
    if (new T() is Widget)
    {
       // Log widget-specific fields
    }
}

`if (T is Widget)`. But it's better to avoid such conversion – Pavel Anikhouski Aug 08 '19 at 12:43

surely if you're using generics then half the point is that you don't really care what the type is – ADyson Aug 08 '19 at 12:43

`typeof(T)` is never `ISomething`. It is `Type`. – Patrick Hofman Aug 08 '19 at 12:44
@PavelAnikhouski That gives an error: `'T' is a type, which is not valid in the given context` – Anthony Faull Aug 08 '19 at 12:46
