namespace ManageDocumentSetTemplate
{
    class Program
    {
        static void Main(string[] args)
        {
             int count = 0;
             string resultLabel="";
            //Get the Shared Documents document libary

            SPWeb currentWeb = SPContext.Current.Web;
            SPDocumentLibrary sharedDocuments = (SPDocumentLibrary)currentWeb.Lists["Shared Documents"];
            //Loop though all the folders. Some of them will be document sets
            //NOTE: don't use the sharedDocuments.Folders collection! Use sharedDocuments.RootFolder.SubFolders

            foreach(SPFolder currentFolder in sharedDocuments.RootFolder.SubFolders)
            {
                //Get the corresponding document set

                DocumentSet currentDocSet = DocumentSet.GetDocumentSet(currentFolder);
                //Strangely the previous line always returns a document set object
                //Even if the current folder is not a document set. So we use the
                //following test to find out if the current folder is a document set
                if (currentDocSet.Item != null)
                {
                    //This folder is a document set. Increase the count
                    count += 1;
                    //Read some properties of the document set
                    resultLabel += "Name: " + currentFolder.Name + "<br />";
                    resultLabel += "Content Type: " + currentDocSet.ContentType.Name + "<br />";
                    resultLabel += "Document Count: " + currentDocSet.Folder.ItemCount + "<br />";
                    resultLabel += "Welcome Page: " + currentDocSet.WelcomePageUrl + "<br /><br />";
                }
            }
            //Display the count
            Console.WriteLine(count.ToString());
        }
    }
}
