How do I append a text file to another text file


How could I append a text file to another text file. Let's say that I have a
File1 and I want to append File2 at the end of File1, how would I do that?

Have a look at the following code from MSDN library.



using System;
using System.IO;

class Test
public static void Main()
string path = @"c:\temp\MyTes t.txt";
// This text is added only once to the file.
if (!File.Exists(p ath))
// Create a file to write to.
using (StreamWriter sw = File.CreateText (path))
sw.WriteLine("H ello");
sw.WriteLine("A nd");
sw.WriteLine("W elcome");

// This text is always added, making the file longer over time
// if it is not deleted.
using (StreamWriter sw = File.AppendText (path))
sw.WriteLine("T his");
sw.WriteLine("i s Extra");
sw.WriteLine("T ext");

// Open the file to read from.
using (StreamReader sr = File.OpenText(p ath))
string s = "";
while ((s = sr.ReadLine()) != null)
Console.WriteLi ne(s);
