declaring a delegate array
We can also declare a delegate array. However, each element of the delegate array must be of same signature in terms of input arguments and return types.
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication10 { class Program { delegate double DoubleOp(double x); static void Main(string[] args) { /* DoubleOp[] operations = new DoubleOp[2]; operations[0] = Program.MultiplyByTwo; operations[1] = Program.getSquare; Console.WriteLine( operations[0](10) ); Console.WriteLine(operations[1](20)); */ DoubleOp[] operations = { Program.MultiplyByTwo, Program.getSquare }; foreach(DoubleOp op in operations) { Console.WriteLine( op(10) ); } } public static double MultiplyByTwo(double value) { return value * 2; } public static double getSquare(double value) { return value*value; } } }
