    Problem with StreamReader off of a button


    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()
            } //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
    This is the dummy text file I am using:
    ==========  GENERAL INFO  ==========
    ==========  SERVER USAGE  ==========
    Resource            Size GiB  Used GiB  Avail GiB  Use%  Cleanable GiB*

    ------------------  --------  --------  ---------  ----  --------------
    * Estimated based on last cleaning of 2011/02/15 06:37:04.

    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!
