Restricting T to string and int?

Asked 2009-01-18T12:25:43.473

I have built myself a generic collection class which is defined like this.

public class StatisticItemHits<T>{...}

This class can be used with int and string values only. However this

public class StatisticItemHits<T> where T : string, int {...}

won't compile. What am I doing wrong?

c# class generics types

You could make StatisticItemHits<T> an abstract class and create two subclasses:

StatisticItemHitsInt : StatisticItemHits<int>{}

StatisticItemHitsString : StatisticItemHits<string>{}

That way there can only be an int and string-representation of StatisticItemHits
