c# additg items to current list


I have folowing code:

        public static void HandleInfo()
            List<Info> list = new List<Info>();

                switch (name)
                    case "INFOS":

  public static List<Info> InfoList(List<Info> list)

            list.Add(new Info() { ID = _ID });
            List<Info> SortedList = list.OrderBy(o => o.ID).ToList();

            var firstItem = SortedList.ElementAt(0);

            return SortedList;

		public class Info
			public long UID { get; set; }            

Open in new window

Problem is my code is overriding list at every call to HandleInfo. So element count is always 1.

What i want is add items to list instead of creating new one each time function is called.

thank you

Your list needs to be a member variable of the class, not the local variable of the HandleInfo function. This line needs to be removed from the function.
List<Info> list = new List<Info>();

Open in new window

Instead, you should have a private variable in your class:
List<Info> list;

Open in new window

And the constructor of the class should create it:
list = new List<Info>();

Open in new window
