C# StreamReader, “ReadLine” For Custom Delimiters

Question

What is the best way to have the functionality of the StreamReader.ReadLine() method, but with custom (String) delimiters?

I\'d like to do something like:

Answer 1

    public static String ReadUntil(this StreamReader streamReader, String delimiter)
    {
        StringBuilder stringBuilder = new StringBuilder();

        while (!streamReader.EndOfStream)
        {
            stringBuilder.Append(value: (Char) streamReader.Read());

            if (stringBuilder.ToString().EndsWith(value: delimiter))
            {
                stringBuilder.Remove(stringBuilder.Length - delimiter.Length, delimiter.Length);
                break;
            }
        }

        return stringBuilder.ToString();
    }
