c# specific word count

Lee Marsden

Hi all,

I am a complete Novice at C# and have been asked by my company to create a small application that performs the following.

we have several servers with log files on them, what we want to to is read the log files and once read search the log file for specific words.

for example we want to search the log files for mainly the words error and display how many errors are contained in the log file.

at the moment I have created a app that has a text box that just displays the log file then at the bottom I have a two text boxes and one button. one text box where you can specify the word you want to search for and the other displays the result once the button is clicked

I would like some help on getting the search to work and to display the amount of times the word was found in the log file

Any help much appreciated

thanks

My suggestion is not C#-related. The best way to search for a term is a small command-line utility called grep. You can download a Windows version - http://gnuwin32.sourceforge.net/packages/grep.htm

You could then write a small batch file to automate what you want to do. Using grep is very easy. There would be plenty of tutorials around that could get you up and running in minutes.

Here's to get you started. Play around with it a bit. And have a research on StreamReader class.

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 WindowsApplication3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        // I added 3 textboxes
        //      txtLogFile, txtKeyword, txtKeyCount
        // and 1 button
        //      btnSearch

        private void btnSearch_Click(object sender, EventArgs e)
        {
            // opens the file
            StreamReader streamReader = new StreamReader(txtLogFile.Text);

            // puts all the contents of the file in a string
            string fileContent = streamReader.ReadToEnd();

            int index = -1;
            int keyCount = 0;

            do
            {
                index = fileContent.IndexOf(txtKeyword.Text, ++index);

                if (index >= 0)
                {
                    // keyword found. increment count
                    keyCount++;
                }
            } while (index >= 0);

            // closes the file
            streamReader.Close();

            // save value in textbox
            txtKeyCount.Text = keyCount.ToString();
        }
    }
}

CHeers,
