Write a console simple program to find a list of repeated string in text file – sample

The program below is to find a string “Login.aspx” in a IIS log named “u_ex110418.log”.


using System.IO;


namespace ConAppIO


  class Program


    static void Main(string[] args)



      int intCount = 0;




        // Create an instance of StreamReader to read from a file.

        // The using statement also closes the StreamReader.

        using (StreamReader sr = new StreamReader(“u_ex110418.log”))


          String line;

          // Read and display lines from the file until the end of

          // the file is reached.

          while ((line = sr.ReadLine()) != null)


            //if the string matches

            int pos = line.IndexOf(“Login.aspx”);

            if (pos > -1)







      catch (Exception e)


        // Let the user know what went wrong.

        Console.WriteLine(“The file could not be read:”);








Drawback of this program is it only counts once occurrence of the string in a line.
