asp.net

Use List.AddRange(collection As IEnumerable(Of T)) method.

It allows you to append at the end of your list another collection/list.

Example:

List<string> initialList = new List<string>();
// Put whatever you want in the initial list
List<string> listToAdd = new List<string>();
// Put whatever you want in the second list
initialList.AddRange(listToAdd);

Try using list.AddRange(VTSWeb.GetDailyWorktimeViolations(VehicleID2));


  1. Use Concat or Union extension methods. You have to make sure that you have this declaration using System.Linq; in order to use LINQ extensions methods.

  2. Use the AddRange method.


Use .AddRange to append any Enumrable collection to the list.
