this is not a question, but an application to find common lines among text files, as long as you click "read new text file" button, it compares it to the listview and removes the uncommon items from the listview. I find this application very useful, hope you will like it too, as well as the project i also attach three sample files.

Form1.cs :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;

namespace CommonText
{
	public partial class Form1 : Form
	{
		public Form1()
		{
			InitializeComponent();
		}
		private bool firstRead = true;
		private void btnReset_Click(object sender, EventArgs e)
		{
			listView1.Items.Clear();
			listView2.Items.Clear();
		}

		private void btnReadNew_Click(object sender, EventArgs e)
		{
			if (openFileDialog1.ShowDialog() == DialogResult.OK)
			{
				listView2.Items.Add(Path.GetFileName(openFileDialog1.FileName));
				TextReader tr = new StreamReader(openFileDialog1.FileName);
				string input = null;
				if (firstRead)
				{
					while ((input = tr.ReadLine()) != null)
						listView1.Items.Add(input);
					tr.Close();
					firstRead = false;
				}
				else
				{

					string lines = File.ReadAllText(openFileDialog1.FileName);
					foreach (ListViewItem lvi in listView1.Items)
					{
						if (lines.Contains(lvi.Text) == false)
							listView1.Items.Remove(lvi);
					}
					
				}
			}
		}
		
	}
}

Form1.Designer.cs :

namespace CommonText
{
	partial class Form1
	{
		/// <summary>
		/// Required designer variable.
		/// </summary>
		private System.ComponentModel.IContainer components = null;

		/// <summary>

		{
			if (disposing && (components != null))
			{
				components.Dispose();
			}
			base.Dispose(disposing);
		}
