Alternative to ReadLine?

I'm trying to read some files with ReadLine, but my file have some break lines that I need to catch (not all of them), and I don't know how to get them in the same array, neither in any other array with these separators... because... ReadLine reads lines, and break these lines, huh?

I can't replace these because I need to check it after the process, so I need to get the breaklines AND the content after that. That's the problem. How can I do that?

Here's my code:

public class ReadFile
    string extension;
    string filename;
    System.IO.StreamReader sr;

    public ReadFile(string arquivo, System.IO.StreamReader sr)
        string ext = Path.GetExtension(arquivo);

        sr = new StreamReader(arquivo, System.Text.Encoding.Default); = sr;
        this.extension = ext;
        this.filename = Path.GetFileNameWithoutExtension(arquivo);

        if (ext.Equals(".EXP", StringComparison.OrdinalIgnoreCase))
        else MessageBox.Show("Extensão de arquivo não suportada: "+ext);


    public void ReadEXP(string arquivo)

        string line = sr.ReadLine();

        string[] words;
        string[] Separators = new string[] { "<Segment>", "</Segment>", "<Source>", "</Source>", "<Target>", "</Target>" };

        string ID = null;
        string Source = null;
        string Target = null;

        DataBase db = new DataBase();

        while ((line = sr.ReadLine()) != null)


                if (line.Contains("<Segment>"))
                    ID = "";
                    words = line.Split(Separators, StringSplitOptions.None);
                    ID = words[0];
                    for (int i = 1; i < words.Length; i++ )
                        ID += words[i];
                    MessageBox.Show("Segment[" + words.Length + "]: " + ID);
                if (line.Contains("<Source>"))
                    Source = "";
                    words = line.Split(Separators, StringSplitOptions.None);
                    Source = words[0];
                    for (int i = 1; i < words.Length; i++)
                        Source += words[i];
                    MessageBox.Show("Source[" + words.Length + "]: " + Source);
                if (line.Contains("<Target>"))
                    Target = "";
                    words = line.Split(Separators, StringSplitOptions.None);
                    Target = words[0];
                    for (int i = 1; i < words.Length; i++)
                        Target += words[i];
                    MessageBox.Show("Target[" + words.Length + "]: " + Target);

                    db.PopulateTable_EXP(ID, Source, Target);

                    MessageBox.Show("ID: " + ID + "\nSource: " + Source + "\nTarget: " + Target);

            catch (IndexOutOfRangeException e)
                MessageBox.Show("ID: " + ID + "\nSource: " + Source + "\nTarget: " + Target);




If you are trying to read XML, try using the built in libaries, here is a simple example of loading a section of XML with <TopLevelTag> in it.

var xmlData = XDocument.Load(@"C:\folder\file.xml").Element("TopLevelTag");
if (xmlData == null) throw new Exception("Failed To Load XML");

Here is a tidy way to get content without it throwing an exception if missing from the XML.

var xmlBit = (string)xmlData.Element("SomeSubTag") ?? "";

If you really have to roll your own, then look at examples for CSV parsers, where ReadBlock can be used to get the raw data including line breaks.

private char[] chunkBuffer = new char[4096];
var fileStream = new System.IO.StreamReader(new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite));
var chunkLength = fileStream.ReadBlock(chunkBuffer, 0, chunkBuffer.Length);
