Problem with StreamReader off of a button

[CWhite1989]

Hello,

I am trying to make a program off of a Windows Forms Application. I am using Microsoft Visual Studio 2008 3.5 framework. The language is C#. The purpose of this program is for the user to browse through a file dialog to find a text file off of a button. When the user clicks the button, the directory is stored in a text box. After this, there's another button where the user will click Run. When this happens, a Stream Reader will read through the selected file inside of the text box. The Output/result will display in a multiline text box below.

Here's the code:

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

using System.Windows.Forms;

namespace TI
{
    public partial class TIGUI : Form
    {
        //Form that shows a browse feature and a run button

        //default contructor
        public TlGUI()
        {


         InitializeComponent();

        } //end constructor

        //handles click event of btnBrowse_Click
        private void btnBrowse_Click(object sender, EventArgs e)
        {
            
                //When clicked, method opens up a browse feature
                //Provided by VS
                OpenFileDialog OpenFileDialog1 = new OpenFileDialog();
                //  OpenFileDialog1.InitialDirectory = @"C:\";
                OpenFileDialog1.Filter = "Text|*.txt|All|*.*";
                if (OpenFileDialog1.ShowDialog() == DialogResult.OK)

                    txtString.Text = OpenFileDialog1.FileName;
                btnBrowse.Enabled = true;
        } //end method btnBrowse_Click


        //handles click event of btnRun_click
        private void btnRun_Click(object sender, EventArgs e)
        {
            string line = "";
            bool print = false;
            using (StreamReader reader = new StreamReader(txtString.Text))
            {
                while (reader.EndOfStream)
                { 
                    // Read line and place into string..we will use line in our following IF's
                    line = reader.ReadLine();
                    if (line == "==========  GENERAL INFO  ==========")
                        print = false;
                    // If line == Server Usage Header then stop printing
                    if (line == "==========  SERVER USAGE  ==========")
                        print = true;

                    if (print == true)
                        txtResult.Text = line; 

                }//End while statement
            }//End using StreamReader
        }//End of Method btnRun_Click
    }//End of Class
}//End of Namespace

the bold area is where i think the issue is. I receive no errors, but when i debug the program, it only reads the last line.

if anyone has any questions or can give suggestions, please ask and I'll be happy to cooperate.

Thank you!
