Is it possible for a function to return two values?

Question

Is it possible for a function to return two values? Array is possible if the two values are both the same type, but how do you return two different type values?

Answer 1

To return 2 values I usually use Pair class from http://blog.o-x-t.com/2007/07/16/generic-pair-net-class/. If you need to return from method 2 values that describe the range, e.g. From/To or Min/Max, you can use FromToRange class.

public class FromToRange
    {
        public T From { get; set; }
        public T To { get; set; }

        public FromToRange()
        {
        }

        public FromToRange(T  from, T  to)
        {
            this.From = from;
            this.To = to;
        }
        public override string ToString()
        {
            string sRet = String.Format("From {0} to {1}", From, To);
            return sRet;
        }
        public override bool Equals(object obj)
        {
            if (this == obj) return true;
            FromToRange pair = obj as FromToRange;
            if (pair == null) return false;
            return Equals(From, pair.From) && Equals(To, pair.To);
        }

        public override int GetHashCode()
        {
            return (From != null ? From.GetHashCode() : 0) + 29 * (To != null ? To.GetHashCode() : 0);
        }

    }
