I have a code like this..

class ABC
{
   public string Name, Phone; 
 
   public static IEnumerable<ABC> GetList()
   {
      List<ABC> foo = new List<ABC>();
 
      //Some COde here
      return foo; 
   }
}
 
Class A
{
   private void GetList()
   {
      IEnumerable<ABC> abc = ABC.GetList();
      foreach (ABC newitem in abc)
      {
         ListViewItem li = new ListViewItem();
         li.Text = newitem.Name;
         li.Tag = newitem; //<<<<<<<<<<<<< Is this Possible ??? 
         ListView1.Items.Add(li);
      }
   }
}


I want to know If I can assign an object to the Tag Property of ListViewItem ??
How come it be accessible outside since the object resides inside a function ??
Will it cause any problems in future ?? Memory and so.... Frown | :( Please Helpp :(

Yes, that's what the Tag property is there for.

The object is accessible outside the function because you are assigning a reference to it. Since there is a reference to it, it's not garbage collected and it exists outside the function where it is assigned.

It should not cause any problems in the future unless you use events on the object. Then you would need to remember to release the events before assigning the object to null so that the garbage collector will pick it up and destroy it. Simply using it as a reference like you do above will not cause any issues, I do it quite frequently.
