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

......................EMS-SoftwareVersion-\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0...........................

String.Join(",",lines)

fails after this does not join lines

    You could replace \0 first 

    string[] lines = {
    "......................EMS-SoftwareVersion-\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0...........................",
    "......................EMS-SoftwareVersion-\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0..........................."

};

var results = string.Join(",", lines.Select(x => x.Replace("\0", "")).ToArray());
Console.WriteLine(results);

    Do you want to display \0 in the result string?

    If this is the case, then you can follow Karen's approach, the difference is to replace \0 with \\0. 

           var results = string.Join(",", lines.Select(x => x.Replace("\0", "\\0")).ToArray());

    This question has nothing to do with String.Join, but these characters are escaped.
