TrimEnd of strings help needed!

Ok, I'm a flash developer, comfortable with actionscripting... so keep this in mind and thanks for any help.

I got some code from a german site that pulled the ID tags from a directory of mp3s. This is for a client who wants to populate a flash mp3 player with his own music. Anyways, I got the flash part, which will pull the data from an XML file. What I want is for the client to populate the ID tags of the mp3s, the .NET page reads that and creates an xml file out of it. So here's the code:

<script language="C#" runat="server"
private static String ConvertByteToString(byte[] bytes, int pos1, int pos2)
{
 //pos2 muß größer oder gleich pos1 sein und
 //pos2 darf Länge des Arrays nicht überschreiten
 if ((pos1 > pos2) || (pos2 > bytes.Length - 1))
 {
 throw new ArgumentException("Aruments out of range");
 }
 //Länge des zu betrachtenden Ausschnittes
 int length = pos2 - pos1 + 1;
 //neues Char-Array anlegen der Länge length
 Char[] chars = new Char[length];
 //packe alle Bytes von pos1 bis pos2 als
 //Char konvertiert in Array chars
 int started = 0;
 for (int i = 0; i < length; i++)
 {
 chars[i] = Convert.ToChar(bytes[i + pos1]);
 }//end for
 //konvertiere Char-Array in String und gebe es zurück
 return new String(chars);
}
void Page_Load(object s, EventArgs e)
{
 DirectoryInfo di = new DirectoryInfo("C:/mp3directory");
 FileInfo[] rgFiles = di.GetFiles("*.mp3");
 String xmlcontent = "<?xml version='1.0' standalone='yes'?><songs>";
 foreach(FileInfo fi in rgFiles)
 {
//mp3 parser section
Stream s1 = fi.OpenRead();
byte[] bytes = new byte[128];
s1.Seek(-128, SeekOrigin.End);
int numBytesToRead = 128;
int numBytesRead = 0;
while (numBytesToRead > 0) {
int n = s1.Read(bytes, numBytesRead, numBytesToRead);
if (n==0) {
break;
}
numBytesRead += n;
numBytesToRead -= n;
}
s1.Close();
String tag = ConvertByteToString(bytes, 0, 2);
//if (tag != "TAG") {
//return false;
//}
String m_title = ConvertByteToString(bytes, 3, 32);
m_title = m_title.TrimEnd();
String m_artist = ConvertByteToString(bytes, 33, 62);
String m_comment = ConvertByteToString(bytes, 97, 126);
//m_album = ConvertByteToString(bytes, 63, 92);
//m_year = Int32.Parse(ConvertByteToString(bytes, 93, 96));
//m_genre = bytes[127];
//end mp3 parser section
 xmlcontent = xmlcontent + "<song title='"+m_title+"' artist='"+m_artist+"' path='" + fi.Name + "' />";
 }
 xmlcontent = xmlcontent + "</songs>";
 //xmlcontent = Regex.Replace(xmlcontent, " ", "*");
 FileInfo t = new FileInfo("C:/mydirectory/songInfo.xml");
 StreamWriter Tex =t.CreateText();
 Tex.WriteLine(xmlcontent);
 Tex.Close();
 Response.Write("Radio Listings created.");
Response.Write(xmlcontent);
}
</script>

Problem is, the silly thing is creating a string with what looks like TONS of extra spaces at the end. What I guess it's doing is creating a string 32-3 characters long for the title (as an example). I tried using TrimEnd, but that didn't work. I even tried just as a test to replace all the spaces with asterisks (you can see it commented above), but even that didn't work.

It looks something like this: <song title='Hey Ya! ' artist='Outkast ' path='HeyYa.mp3' /
Very frustrating.

Thanks!Not exactly sure I was clear about what the problem is. If you look above at the xml that gets generated, you'll notice after the title there is a space. In the xml file that is created, there are a ton of spaces, but my pasting in the example strips out the spaces.

Anyways, I _think_ I figured it out. I removed the Streamwriter part and replaced it with XmlTextWriter. This changed the spaces to "�", and flash just ignores that. Everything works exactly as it should. I'm assuming I have a encoding issue with transferring bytes to strings and then to xml. Eh... it works, so who cares I suppose.
