Can anyone suggent me the procedure to reading a file and then writing to an array specific parts of a binary file, or maybe Im thinking of writing it to another file instead of using an array. I know I have to use the System.IO stream classes. Well thanks in advanced.

Yeah.. I wrote these two functions to serialize a file to send over a web service. They will do the trick for you.

public static bool UploadFile(string strPath, byte[] btFile)
{
try
{
FileStream objFileStream = new FileStream(strPath, FileMode.CreateNew, FileAccess.Write, FileShare.None);
objFileStream.Write(btFile, 0, btFile.Length);
objFileStream.Close();
}
catch (FieldAccessException e)
{
// write to application log
return false;
}
return true;
}
public static byte[] DownloadFile(string strFile)
{
byte[] btFile;
try
{
FileStream objFileStream = new FileStream(strFile, FileMode.Open, FileAccess.Read, FileShare.Read);
btFile = new Byte[objFileStream.Length];
objFileStream.Read(btFile, 0, (int) objFileStream.Length);
objFileStream.Close();
}
catch (Exception e)
{
return null;
}
return btFile;
}

Thanks it was a great help.Now I am trying to just a line from the file to a richtextbox, I guess the properties of the .rtf file are not kept.
{
//READ A LINE
String scfile=dlgOpen.FileName;
StreamReader srReadline=new StreamReader ((System.IO.Stream )File.OpenRead(scfile),System.Text.Encoding.ASCII );
srReadline.BaseStream.Seek (0,SeekOrigin.Begin );
while(srReadline.Peek () > -1)
rtb_try.Rtf =srReadline.ReadLine() ;

srReadline.Close();
}
If you know a way of keeping the properties it would be alot of help..
thanks
