How to remove multiple selected items in ListBox?

Question

My windows form contains two listboxes. Listbox1 contains some items in it and listbox2 is empty. When I press a button on the form, then multiple selected items from listbox1 should be removed from Listbox1 and copied to Listbox2.

I tried with foreach loop on listbox1.SelectedItems but it removes only 1 item from list.

Anyone has solution or code for this?

Answer 1

You could do all in a single loop. You should use a simple for and loop backwards on SelectedIndices:

private void button1_Click(object sender, EventArgs e) 
{ 
    for(int x = listBox1.SelectedIndices.Count - 1; x>= 0; x--)
    { 
        int idx = listBox1.SelectedIndices[x];
        listBox2.Items.Add(listBox1.Items[idx]); 
        listBox1.Items.RemoveAt(idx);
    } 
} 

Answer 2

you must store The values, you want to delete in other palce and then delete them from List,Here is sample code:

private void button1_Click(object sender, EventArgs e)
{
    ArrayList tmpArr = new ArrayList();
    foreach (object obj in listBox1.SelectedItems)
    {
        listBox2.Items.Add(obj);
        tmpArr.Add(obj);
    }
    foreach (object obj in tmpArr.ToArray())
    {
        listBox1.Items.Remove(obj);
    }
}
