why don't you split the string like string[] mydir = dirstring.Split('\');

The mistake of your approach is: '\' is not portable. Did you know that?
No, it's better to use library methods -- please see my answer.

You have to tell us on which conditions should you split the path (i.e. on what criteria you decide the place where you want to split the path). An example without that is pretty useless. In which case, the answer given by 'digimanus' is pretty suitable :)

You are right, but that method is not suitable by the reason I explained in my comment above; please see my answer.

Just write the code to do it. Use String.Substring() or something like it.

No! There are some problem in this approach.

No, don't split anything and don't use direct string manipulations as other advised.

Instead, first extract the directory using System.IO.Path.GetDirectoryName; see:
http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname.aspx[^].

On the result, use the method System.IO.Directory.GetParent required number of times, see:
http://msdn.microsoft.com/en-us/library/system.io.directory.getparent.aspx[^].

Unlike direct string manipulations where you can easily make a mistake, these methods are reliable and platform independent.
