How to delete last line in a text file?

Question

I have a simple log text file with the extension of .txt with a white space line at the end of that text file every time the log file is generated from a 3rd party program.<

Answer 1

Use this method to remove the last line of the file:

public static void DeleteLastLine(string filepath)
{
    List lines = File.ReadAllLines(filepath).ToList();

    File.WriteAllLines(filepath, lines.GetRange(0, lines.Count - 1).ToArray());

}

Edit: Realized the lines variable didn't exist previously, so I updated the code.
