C# reading a text line by line, where line delimiter is a custom

I have an array of bytes (say byte[] data), which contains text with custom line delimiters, for example: "\r\n" (CRLF "\x0D\x0A"), "\r", "\n", "\x0D\x0A\x0D" or even "@".

At the moment I'm going to use the following solution:

  1. Normalize line breaks to CRLF (here is an example how to normalize CRLF What is a quick way to force CRLF in C# / .NET?)

  2. Use StringReader to read text line by line

    
using (String Reader sr = new StringReader(data.ToString()))
{
    string line;
    while ((line = sr.ReadLine()) != null)
    {
        // Process the line 
    }
}

I'm using C#, .NET 3.5. Is there any better solution?

Thanks.

Use regexp instead, which will give you much more flexibility.

Here's one option to limit calls to string.Replace to just the multi-character delimiters.

private static readonly char[] DelimiterChars = { '\r', '\n', '@' };
private static readonly string[] DelimiterStrings = { "\r\n\r", "\r\n" };

Then later...

string text = Encoding.ASCII.GetString(data);
foreach (string delim in DelimiterStrings)
    text = text.Replace(delim, "\n");

foreach (string line in text.Split(DelimiterChars))
{
    // processing here
}
