Search i tekstfil
Jeg har lavet en aspx-side, som benytter en ".cs" fil (som jeg også har lavet). På aspx-sden skriver man en streng ind, som .cs-filen søger et tekstdokument igennem for. Alt afhængig af, om der returneres true eller false, så skal der stå noget tekst i en andet tekstbox. Men det fungerer ikke.Sådan ser flerne ud:
Aspx:

using System.Web.UI.HtmlControls;

{
/// <summary>

public class MovieSearch : System.Web.UI.Page
{

protected System.Web.UI.WebControls.TextBox TextBox2;
protected System.Web.UI.WebControls.Button Button1;
MovieLed film;
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
film=new MovieLed();
}
#region Web Form Designer generated code

//

InitializeComponent();
base.OnInit(e);

this.TextBox1.TextChanged += new System.EventHandler(this.TextBox1_TextChanged);
this.Button1.Click += new System.EventHandler(this.Button1_Click);

}

private void TextBox1_TextChanged(object sender, System.EventArgs e)

TextBox2.Text.Insert(0, "Testing");
bool svar=film.search(TextBox1.Text.ToString());
TextBox2.Visible=true;
if(svar==true)
TextBox2.Text.Insert(0, "I've got the movie. Give me a message through ICQ or something and I'll put it in my share!");
if(svar==false)
TextBox2.Text.Insert(0, "Sorry - no luck this time!");

using (StreamReader sr = new StreamReader("G:\\FromOldHardDrive\\Movies\\Movies.txt"))
{
String line;
while ((line = sr.ReadLine()) != null)
{
line.Insert(0, "-");
if(line==title)
found=true;
}
}
}
catch (Exception e)
{
// Let the user know what went wrong.
Console.WriteLine("The file could not be read:");
Console.WriteLine(e.Message);

Console.WriteLine("Found før return er: " + found);

Nogle gode forslag til løsning?
