Question

Target file:

Hello
World

Code:

if (file != null)
{
    //Read file one character at a time
    StreamReader reader;
    reader = new StreamReader(file);
    do
    {
        int s = reader.Read();
        char sC = (char)s;
        if (sC.Equals(Environment.NewLine))
        {
            Console.WriteLine("+1");
        }
        Console.WriteLine((char)s);
    } while (!reader.EndOfStream);
    reader.Close();
    reader.Dispose();
}

Output:

H
e
l
l
o




W
o
r
l
d

So (sC.Equals(Environment.NewLine)) obviously doesn’t detect a platform independent newline when reading one char at a time.. how do I do this?

Answer 1

try this instead

if (sC.Equals('\n'))

If you are sure there will always be a \r after the \n then you can swallow it with another reader.Read(); call. Example:

if (sC.Equals('\n')) {
   reader.Read()
   Console.WriteLine("+1");
}
