Can use the streamReader to read in the lines and use a Regex to match certain lines...if there is a pattern you want to match.

example: 

using System.IO;
using System.Text.RegularExpressions;

Regex pattern = new Regex("^B");
List<string> lines = new List<string>();
using (StreamReader reader = File.OpenText(fileName))
{
    while (!reader.EndOfStream)
    {
        string line = reader.ReadLine();
         Match patternMatch = pattern.Match(blah);

            if (patternMatch.Groups.Count > 0)
            {
                lines.Add(blah);
            }
    }
}

Looks like every line in your sample that is not "valid" includes the text "+CGML". In that case, this should do the trick:

public static IEnumerable<string> GetText(string filePath)
{
    using (StreamReader sr = new StreamReader(filePath))
    {
        string line;
        while ( (line = sr.ReadLine()) != null)
        {
           if (line.IndexOf("+CMGL") < 0) yield return line;
        }
    }
}

The following will get you your lines into a string array:

string[] lines = File.ReadAllLines(pathToFile);

So:

lines[2];
lines[4];

Will get you those lines.

See the msdn documentation for ReadAllLines.

Read the file with a StreamReader and use the ReadLine method, that will read the file one line at a time.

using (StreamReader reader = File.OpenText(fileName))
{
    while (!reader.EndOfStream)
    {
        string line = reader.ReadLine();
        // do something with the line
    }
}
