Question

I have a file. When I open it in Notepad I see charachters in a single line. However, if I open that file in any other application like WordPad or Notepad++. I can see irregular line breaks between charachters and they appear in multiple lines. These line breaks also appears if I do reader.Readline(). How can I perform Notepad like line read in C#?

Sorry for second answer from me, but I just realised that you could use peek to get next character and check if current and next are \r\n, like so:

var path = 'c:/test.txt';  File.WriteAllText(path, 'a\nb\r\nc');  using (var stream = File.OpenRead(path)) using (var reader = new StreamReader(stream, Encoding.ASCII)) {     var lineBuilder = new StringBuilder();     string line;     char currentChar;     int nextChar;     while (!reader.EndOfStream)     {         currentChar = (char)reader.Read();         nextChar = reader.Peek();          if (!(currentChar == '\r' && nextChar == '\n'))         {             lineBuilder.Append(currentChar);         }          if((currentChar == '\r' && nextChar == '\n') || nextChar == -1)         {             line = lineBuilder.ToString();             Console.WriteLine(line);              lineBuilder = new StringBuilder();              reader.Read();         }     } }
