 Is it .doc or .txt.

 If its .doc then how can you able to display it in a .txt file.

i understand ur coding when i used this the content thar are displayed in a text box is not in text format.here i attached the codings.

Hi,

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

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

        private void button1_Click(object sender, EventArgs e)
        {
            string pathSource = @"d:\sample.txt";
           
            try
            {
                using (FileStream fsSource = new FileStream(pathSource,
                    FileMode.OpenOrCreate, FileAccess.ReadWrite))
                {
                    byte[] bytes = new byte[fsSource.Length];
                    int numBytesToRead = (int)fsSource.Length;
                    int numBytesRead = 0;
                    while (numBytesToRead > 0)
                    {
                        int n = fsSource.Read(bytes, numBytesRead, numBytesToRead);

                        if (n == 0)
                            break;

                        numBytesRead += n;
                        numBytesToRead -= n;
                    }
                    numBytesToRead = bytes.Length;

                    string str = System.Text.ASCIIEncoding.ASCII.GetString(bytes);

                    textBox1.Text = str;
                }
            }
            catch (FileNotFoundException ioEx)
            {
                Console.WriteLine(ioEx.Message);
            }
        }

       // Clear text box
        private void button2_Click(object sender, EventArgs e)
        {
            textBox1.Text = string.Empty;
        }
    }
}

This the Code.

Add System.Text namespace to resolve the error.

Hi Kiruthika,

Just download the project created as your need.

I attached the project in this reply.

Thanks. Dont forget to make this as ANSWER.

And also read my articles.

Hi Kiruthika,

The reference fot StringBuilder is System.Text

.Net library - mscorlib (in mscorlib.dll).

in read,append methods the error will occur

Error 1 'System.IO.FileStream' does not contain a definition for 'read' and no extension method 'read' accepting a first argument of type 'System.IO.FileStream' could be found (are you missing a using directive or an assembly reference?) 

Hi Kiruthika,

Just place the cursor on that StringBuilder and press CTRL+.(Dot) else right click on StringBuilder and choose Resolve. it will add reference automatically.

ya i already try to use the string buffer but the
error : The type or namespace name 'StringBuffer' could not be found (are you missing a using directive or an assembly reference.error will occur how can i solve this.

Hi,

Just try this!

 string str = null;
 try {
   FileStream reader = new FileStream("D:/karthi/resume/r1.txt", FileMode.Open,FileAccess.Read);
   char[] buffer = new char[32];
  StringBuilder sb = new StringBuilder();
 int count;
 while ((count = reader.read(buffer, 0, buffer.length)) > -1)
 {
 sb.append(buffer, 0, count);
 }
  reader.close();
  str = sb.toString();
 }
catch (IOException ex)
{
 str = "Failed to load text";
 }

yourTextBox.Text = str;

It works fine.

If you feel this will work for you please Make this is ANSWER
