Converting an absolute pathname to something more personal

I have a pathname C:\Users\<user name>\Documents\Folder returned from using the FileBrowserDialog, that I would prefer to display using the My Documents\Folder.

Other than using

pathname.StartsWith(My.Computer.FileSystem.SpecialDirectories.MyDocuments)

to see if the pathname 'belongs' in My Documents, is there another way of converting the pathname to use My Documents?

You could use this approach which loops the parent directories up to the root:

DirectoryInfo directory = new DirectoryInfo("C:\\Users\\Tim\\Documents\\Folder\\file.ext");
string myDocs = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
bool isMyDocs = directory.FullName == myDocs;
while (!isMyDocs && (directory = directory.Parent) != null)
    isMyDocs = directory.FullName == myDocs;
// use your personal folder-name acc. to isMyDocs

Update:

I should re-phrase the question. I want to end up with shorthand path notation e.g. \My Documents\Folder\file.ext

I thought it would be clear:

string yourFile = "C:\\Users\\Tim\\Documents\\Folder\\file.ext";
string yourDir = Path.GetDirectoryName(yourFile);
DirectoryInfo directory = new DirectoryInfo(yourDir);
string myDocs = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
bool isMyDocs = directory.FullName == myDocs;
while (!isMyDocs && (directory = directory.Parent) != null)
    isMyDocs = directory.FullName == myDocs;
string personalPath = yourDir;
if(isMyDocs)
{
    personalPath = Path.Combine("My Documents", "Folder", Path.GetFileName(yourFile));
}
