I have created this method which is an object factory:
public static T GetService<T>(T serviceInterface)
{
if (serviceInterface.Equals(typeof(IMemberService)))
{
return (T)(object)new MemberService();
}
else if (serviceInterface.Equals(typeof(ILookupService)))
{
return (T)(object)new LookupService();
}
throw new ArgumentOutOfRangeException("No action is defined for service interface " + serviceInterface.Name);
}
Now, I would like to go further and eliminate the need for "serviceInterface" parameter, but my problem is - I don't know how to compare type parameter T to an interface: doing
T.Equals(typeof(ILookupService))
gives compiler error: 'T' is a 'type parameter', which is not valid in the given context.
Any ideas how could I compare a type parameter to an interface?
Thank you, Andrey
