Question

I have a wpf c# application, that loads tasks to a treeView from a text file, the data about the tasks are loading into a list, Im trying to delete data in position I in the list, but i can not figure out how. I have this for loop checking to see if the selected treeView item is equal to the item in position I in the list and if so I wanna delete that item from the list. Here is the for loop which works, im just wondering how to do the actual delete, I’ve tried things such as .delete and .remove which I found on msdna.

for (int i = 0; i < name.Count; ++i)
{
       string selectName = ((TreeViewItem)(treeView1.SelectedItem)).Header.ToString();

       if (selectName == name[i])
       {

       //name.Remove(i) or name.Remove[i] or name[i].Remove
       }
}

If name is a List<T> then you probably want name.RemoveAt(i) if I understand the question correctly.

Alternatively, you could just use name.RemoveAll(n => n == selectName); instead of the for loop.
