comment obtenir l'opérateur ternaire appliqué

Question

J'ai construit une fonction spécifique par le biais du codage. voici mon code:

public static string GetRefNo() 
    { 
     using (DataClassesDataContext db = new DataClassesDataContext()) 
     { 
      string tickPrefix = db.Users.Where(u => u.Username.Equals((String)HttpContext.Current.Session["Username"])).Select(u => u.TicketPrefix).SingleOrDefault(); 
      int xyear = db.Users.Where(u => u.Username.Equals((String)HttpContext.Current.Session["Username"])).Select(u => u.Last_Login_Datetime.Value.Year).SingleOrDefault(); 
      int xmonth = db.Users.Where(u => u.Username.Equals((String)HttpContext.Current.Session["Username"])).Select(u => u.Last_Login_Datetime.Value.Month).SingleOrDefault(); 
      int xday = db.Users.Where(u => u.Username.Equals((String)HttpContext.Current.Session["Username"])).Select(u => u.Last_Login_Datetime.Value.Day).SingleOrDefault(); 
      int xcounter = int.Parse(db.Users.Where(u => u.Username.Equals((String)HttpContext.Current.Session["Username"])).Select(u => u.Counter).SingleOrDefault().ToString()); 
      xcounter++; 
      var query = db.Users.Where(u => u.Username.Equals((String)HttpContext.Current.Session["Username"])).Select(u => u).ToList(); 
      foreach (var item in query) 
      { 
       if (item != null) 
       { 
        db.ExecuteCommand("UPDATE [CRM].[dbo].[tbl_User_master] SET [Counter] = {0} WHERE Ref_no = {1}", xcounter, item.Ref_no); 
       } 
      } 
      return tickPrefix + xyear.ToString().Substring(3, 1) + xmonth.ToString() ? 0.PadLeft(2, '0') + xday.ToString().PadLeft(2, '0') + xcounter.ToString().PadLeft(2, '0'); 
     } 
    } 

maintenant je veux juste vérifier si xmonth.ToString() est inférieur à 10, puis il suffit d'appliquer cette PadLeft(2, '0') autre simple, xmonth.ToString().

s'il vous plaît aidez-moi ....

      } 
      string c = (xcounter < 10) ? xcounter.ToString().PadLeft(2, '0') : xcounter.ToString(); 
      string m = (xmonth < 10) ? xmonth.ToString().PadLeft(2, '0') : xmonth.ToString(); 
      string d = (xday < 10) ? xday.ToString().PadLeft(2, '0') : xday.ToString(); 
      return tickPrefix + xyear.ToString().Substring(3, 1) + m + d + c; 
     } 
    }

Vous êtes à la recherche d'une expression comme ceci:

xmonth < 10 ? xmonth.ToString().PadLeft(2, '0') : xmonth.ToString()
