I have a generic class and I want to enforce that instances of the type parameter are always "cast-able" / convertible from String. Is it possible to do this without for example using an interface?
Possible implementation:
public class MyClass<T> where T : IConvertibleFrom<string>, new()
{
public T DoSomethingWith(string s)
{
// ...
}
}
Ideal implementation:
public class MyClass<T>
{
public T DoSomethingWith(string s)
{
// CanBeConvertedFrom would return true if explicit or implicit cast exists
if(!typeof(T).CanBeConvertedFrom(typeof(String))
{
throw new Exception();
}
// ...
}
}
The reason why I would prefer this "ideal" implementation is mainly in order not to force all the Ts to implement IConvertibleFrom<>.
