If you are targeting .NET 3.5 or above, LINQ:

foreach (string line in lines.Skip(1)) {...}

Although it there is a lot of data, a line-reader may be better, to avoid having to hold all the lines in memory:

public static IEnumerable<string> ReadLines(string path) {
    using(var reader = File.OpenText(path)) {
        string line;
        while((line = reader.ReadLine()) != null) {
            yield return line;
        }
    }
}

then:

foreach(var line in ReadLines(filelocation).Skip(1)) {...}
