Get TFS Team Project Names

Here is a method that returns a List of names of team projects available at Team Foundation Server

public static List<string> GetProjects(TeamFoundationServer tfsServer)

        {

            List <string> listProjects = new List<string>();      

            ICommonStructureService iss = (ICommonStructureService)tfsServer.GetService(typeof(ICommonStructureService));           

            ProjectInfo[] projectInfo = iss.ListProjects();

            foreach (ProjectInfo pi in projectInfo)

            {

                listProjects.Add (pi.Name);

            }                                                

            return listProjects;

        }

Some Registry Methods

Here are a couple of helper methods to work with Windows Registry:
The first method makes sure you get a reference to a registry subkey. If it does not exist it creates one first. The second one is a preferred way to read a registry value.

 public static RegistryKey GetKey(string RegKey)

 {

     RegistryKey Key = Registry.CurrentUser.OpenSubKey(RegKey, true);

     if (Key == null)

     {

         Key = Registry.CurrentUser.CreateSubKey(RegKey);

     }

     return Key;

}

public static string ReadRegistryValue(RegistryKey key, string regValName)

{

     string[] values = key.GetValueNames();

     if (values.Contains(regValName))

          return key.GetValue(regValName).ToString();

     else

          return String.Empty;

}
