如何从listboxitem的内容获取索引？

Question

Is there a way to get a Listbox Item Index by its content? Something like:

id = listbox.Items.Contains("text");

I know that this way I'll get a bool result, but I don't know how to get the item Index. If I could get the Index I could be able to remove items with

listbox.Items.RemoveAt(id);

Answer 1

In WPF

ListBox listBox = new ListBox();   
int index = listBox.Items.IndexOf(item);

Answer 2

Look for the item's index, and then you can remove it with the given method:

int index = myListBox.Items.IndexOf(itemToSearch); 
/*if there is no coincidence, it returns -1, so you must check for that return, else RemoveAt(-1) would give you a runtime error.*/
if (index >=0)
{
myListBox.Items.RemoveAt(index);
}

Answer 3

Assuming the item is not selected but for some reason you just want to find it in the list:

The listbox.items is a listbox object collection: So:

id=listbox.items.IndexOf("text");

will do the trick.
