Displaying a text file in a web form.

I am having difficulty displaying a text file in a web form or windows form. I can do this for an Access data base I created and and it displays the table - how is this different and what controls should I be using to display the hello.txt file? Can anyone help? Thank you,Joe

Look into the classes in the System.IO namespace. There you'll find classes that deal with the file system and can use one of them to open a file and read it into your program.

I will do this thank you Pete. I cross posted this because on reflection I thought the beginners forum would be more appropriate.
Please advise on what to do in an instance such as this. I am trying to work with your answer.

Code:

            string s=string.Empty;
            StreamReader reader=null;
            try
            {
                reader=new StreamReader(@"d:\File.txt",Encoding.ASCII);
                //do the stuff
                s=reader.ReadToEnd();
            }
            catch(Exception exp)
            {
                //...
            }
            finally
            {
                //free the resource
                reader.Close();
            }

boksi,

A moderator can move it for you, which I will do. (The topic ID won't change so the thread will stay intact.)

I have tried the following code in a class which I added to the WebForm1.cs called TextFromFile...it compiles but does not
show my text file in a browser when I do a start without debugging.

using System;
using System.IO;
namespace WebApplication4
{
    /// <summary>
    ///
    /// </summary>

public class TextFromFile
{
    private const string FILE_NAME = "blah.txt";
    public static void Main(String[] args)
    {
        if (!File.Exists(FILE_NAME))
        {
            Console.WriteLine("{0} does not exist.", FILE_NAME);
            return;
        }
        StreamReader sr = File.OpenText(FILE_NAME);
        String input;
        while ((input=sr.ReadLine())!=null)
        {
            Console.WriteLine(input);
        }
        Console.WriteLine ("The end of the stream has been reached.");
        sr.Close();
    }
}

            //
            // TODO: Add constructor logic here
            //
        }
