C# Program to Use Delegate to Call 2 Methods within which First method Prints to Console and Second Method Prints to File

Code:

using System;
using System.IO;
namespace Program
{
    class PrintString
    {
        static FileStream fs;
        static StreamWriter sw;
        public delegate void printString(string s);
        public static void Screen(string str)
        {
            Console.WriteLine("The String is: {0}", str);
        }
        public static void File(string s)
        {
            fs = new FileStream("c:\\sri\\Message.txt",
            FileMode.Append, FileAccess.Write);
            sw = new StreamWriter(fs);
            sw.WriteLine(s);
            sw.Flush();
            sw.Close();
            fs.Close();
        }
        public static void sendString(printString ps)
        {
            ps("C# Program to Use Delegate to Call 2 Methods within which First method Prints to Console and Second Method Prints to File");
        }
        static void Main(string[] args)
        {
            printString ps1 = new printString(Screen);
            printString ps2 = new printString(File);
            sendString(ps1);
            sendString(ps2);
            Console.ReadKey();
        }
    }
}


Output:

The String is : C# Program to Use Delegate to Call 2 Methods within which First method Prints to Console and Second Method Prints to File
