Edit: Clearly this is not possible as C# does not allow static methods in interfaces.
Obviously it would be fairly simple to implement the following interfaces for your own solution
public interface IParsable<T>
{
T Parse(string s);
}
public interface ITryParsable<T> : IParsable<T>
{
bool TryParse(string s, out T output);
}
Having been writing various ways of parsing unknown typed user input data, I would have found having int, decimal, etc, etc implement a version of these interfaces indispensable.
To me it seems like a fairly obvious thing to have included in the System namespace.
Obviously this is not the case. So what is the best way of seeing whether a class "implements" these interfaces?
Checking whether the method exists via Duck Typing seems like a sensible alternative, but Reflection isn't terribly performant.
