  1. private void button1_Click(object sender, EventArgs e)
  2.         {
  3.             int[] b = new int[100000];
  4.             StreamReader sw = new StreamReader("c: \\28D.09N");
  5.             for (int i = 0; i < 5000; i++)
  6.             {
  7.                 b[i] = sw.Read();
  8.                 //int c = sw.Read();
  9.                 //int a = (int)c;
  10.                 Console.WriteLine(b[i]);
  11.             }
  12.             /*SaveFileDialog sv = new SaveFileDialog();
  13.             sv.Filter = "text file|*.txt";

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

Sid: Let me be clear here. You have started over a dozen threads. You have been told this many times. If you can't be bothered to format your questions to make it easier on the volunteers trying to help you, then I wouldn't be surprised if the volunteers here just stopped reading your questions.

Yeah, that is what I am coming to realize from all of your posts... You are expecting the solutions from someone else.

Have you considered that you might have to read up on the functions you are using so you *understand* what they are doing?

For example: Reading the MSDN page for streamreader reveals
StreamReader defaults to UTF-8 encoding unless specified otherwise, instead of defaulting to the ANSI code page for the current system. UTF-8 handles Unicode characters correctly and provides consistent results on localized versions of the operating system.

Do you know for FACT what the contents of the file are and how they were written? Or are you assuming it is ASCII?

HINT: Streamwriter also defaults to UTF-8, so if you wrote the file thinking it was ASCII then it is possible that streamwriter converted it to unicode.
