Question

How to make a for loop that if a listbox has an item that for example has the word "hi" in it it will delete it?

I started working with this but it didnt work:

 if (listBox6.Items.ToString() == " ")
 {
     for (int i = 0; i < listBox6.SelectedItems.Count; i++)
     {
          listBox6.Items.Remove(listBox6.SelectedItems[i]);
     }
 }

you can try like this….

Iterate using an index, starting at the last item:

for (int n = listBox1.Items.count - 1; n >= 0; --n)
{
    string removelistitem = "HI";
    if (listBox1.Items[n].ToString().Contains(removelistitem))
    {
        listBox1.Items.RemoveAt(n);
    }
}
