#535 – Creating a Generic Struct

In addition to generic classes, you can also create a generic struct.  Like a class, the generic struct definition serves as a sort of template for a strongly-typed struct.  When you declare a variable of this struct type, you provide a type for its generic parameter.

    public struct ThreeTuple<T>
    {
        public ThreeTuple(T x, T y, T z)
        {
            X = x;
            Y = y;
            Z = z;
        }

        public T X;
        public T Y;
        public T Z;
    }

    public class Program
    {
        static void Main()
        {
            ThreeTuple<int> intTuple = new ThreeTuple<int>(32, 10, 12);
            int yVal = intTuple.Y;

            ThreeTuple<double> dblTuple = new ThreeTuple<double>(1.2, 3.4, 5.6);
            double yVal2 = dblTuple.Y;
        }
   }
