How to delete last line in a text file?

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.

Therefore is there any methods or codes that I can utilize to delete the last line of the text file?

An example of the log text file:

Sun Jul 22 2001 02:37:46,73882,...b,r/rrwxrwxrwx,0,0,516-128-3,C:/WINDOWS/Help/digiras.chm

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

public static void DeleteLastLine(string filepath)
{
    List<string> 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.
