public static string GetAllExceptionTree(Exception exception) 
    { 
     if (exception is DbEntityValidationException) 
     { 
      StringBuilder validationErrors = new StringBuilder(); 
      DbEntityValidationException ex = exception as DbEntityValidationException; 
      foreach (var error in ex.EntityValidationErrors) 
       foreach (var err in error.ValidationErrors) 
        validationErrors.Append(String.Format("{0}<br/>", err.ErrorMessage)); 

      return validationErrors.ToString(); 
     } 

     StringBuilder sb = new StringBuilder(); 
     do 
     { 
      if (sb.Length != 0) 
       sb.Append("..."); 
      sb.Append(exception.Message); 
      exception = exception.InnerException; 
     } while (exception != null); 

     return sb.ToString(); 
    }
