Backwards traverse of a path in C# -- Directory.GetParent()

image credit

I encountered many time when writing an C# .Net MVC application, I need to access the file structure in the server. I used to get the current running path by

AppDomain.CurrentDomain.BaseDirectory

Then do string manipulation to get to the root that I need and then use the Path class to create the file path I need.

Yet today I discovered the method

Directory.GetParent(path);

Which seems save my time to do the string manipulation to get the parent directory! You can see the smaple code below

void GetParent(string path) 
        {
            try 
            {
                System.IO.DirectoryInfo directoryInfo =
                    System.IO.Directory.GetParent(path);

                System.Console.WriteLine(directoryInfo.FullName);
            }
            catch (ArgumentNullException) 
            {
                System.Console.WriteLine("Path is a null reference.");
            }
            catch (ArgumentException) 
            {
                System.Console.WriteLine("Path is an empty string, " +
                    "contains only white spaces, or " +
                    "contains invalid characters.");
            }
        }
