Compare lines of 2 txt files in C#

I would like to compare lines 2 txt files. I think to do loops, but how? Here is my code to read in 2 files:

Code:

---

StreamReader li = new StreamReader("list.txt" );
StreamReader li2= new StreamReader ("list2.txt" );
string li = li.ReadLine();
string li2 = li2.ReadLine();
while (li != null && li2 != null)
{
Console.Write(li);
Console.Write(li2);
}

---

You want to compare it to say? Display only those that are similar? You are aware that there are tools (and libs) made for that?

I think you need to modify your code with something like this:

Code:

---

using (StreamReader li = new StreamReader("list.txt" ))
using (StreamReader li2 = new StreamReader("list2.txt" ))
{
    while (true)
    {
        if (li.EndOfStream || li2.EndOfStream)
            break;
        string liTxt = li.ReadLine();
        string li2Txt = li2.ReadLine();
        if (!liTxt.Equals(li2Txt))
            Console.WriteLine("Lines different!!!" );
    }
}

Thanks for your code Ashok but I am sorry it fails at while loop. Can you enlighten me where is the problem? I am unable to rectify it.

That may be the error somewhere else in your program, just recheck your code. One more thing, you can also use do while loop which is much handy sometimes.
