Question

Is there a way I can write the following without typing out the whole signature again?

//desired base signature
    public delegate string BaseDelegate<TProfile, TResult>(string requestorID, DateTime sentDate, string serviceID,
        string source, TProfile profile, out DateTime recieved, out DateTime sent, out string psatSystemID, out TResult[] result);

//ugly version of child
public delegate string CurriedDelegate<T>(string requestorId, DateTime sentDate, string serviceId, string source,
T profile, out DateTime recieved, out DateTime sent, out string psatSystemID, out T[] result);

//syntax sugar,doesn't compile
    public BaseDelegate<T,T> CurriedDelegate<T>; //TProfile is same type as TResult

No, there’s no way of doing that, although you could create a CurriedDelegate<T> from a BaseDelegate<TProfile, TResult> if the two type parameters were the same.

It seems to me like a better solution would be to encapsulate the various parameters in a separate type anyway. That really is a horribly long signature to start with, and presumably the parameters are related to each other.

(I’d also try to avoid using so many out parameters – perhaps you’ve actually got two types to encapsulate here, one for input and one for output?)
