Question

I have this piece of code that searches for a folder given a starting directory. Once the folder is found I need the name of it’s parent. The following piece of code works but it is terribly ugly. I have a flag, “sessionFound” to assist with breaking from nested foreach loops. The following works. I was hoping I could get some eyes on this and see if I could get some suggestions on how to make this less verbose and a bit more concise.

Thanks.

    private void SetProjectFolder(string sessionid)
        {

//IoC container gives the root directory to begin search.
            string[] supportDirs = Directory.GetDirectories(ApplicationContainer.SupportDirectory);
            bool sessionFound = false;

            foreach (string directory in supportDirs)
            {
                if (!sessionFound)
                {
                    foreach (string folder in Directory.GetDirectories(directory))
                    {
                        if (!sessionFound)
                        {
                            foreach (string productSubFolder in Directory.GetDirectories(folder))
                            {
                                if (productSubFolder.Contains(sessionid))
                                {
                                    _productName = Directory.GetParent(productSubFolder).Parent.Name;
                                    sessionFound = true;
                                    break;
                                }
                            }
                        }
                        else
                        {
                            break;
                        }
                    }
                }
                else
                {
                    break;
                }
            }
        }

Try this:

private void SetProjectFolder(string sessionid)
    {
        //This will simulate the contains statement
        string searchPattern = string.Format("*{0}*", sessionid);
        string[] supportDirs = Directory.GetDirectories(ApplicationContainer.SupportDirectory, searchPattern);

        foreach (string filteredFolder in supportDirs)
        {
            _productName = Directory.GetParent(filteredFolder).Name;
            break;
        }
    }
