There are no consequences that I know of, and it's not likely to be broken in future versions, because a lot of people will be doing the same as you.

However, the correct way to combine paths in C# is to use Path.Combine, which will remove any extra backslashes for you:

var logFile = Path.Combine(
    ConfigurationManager.AppSettings["LogFileDirectory"],
    ConfigurationManager.AppSettings["SaveLogFileTo"]);
