I use ListBox in my project. When I get data for update then same data show in listbox1 and listbox2. But I try to remove data from listbox1 which is alread in Listbox2

What I have tried:

if (updateById == null) return;
btnSave.CommandArgument = updateById.CityDetailsId.ToString(CultureInfo.InvariantCulture);
BindStateDetails();
ddlState.SelectedValue = Convert.ToString(updateById.StateId);
BindCityList();
//libAdminCity.DataSource = updateById.CityName;
message3 = updateById.VCityId;
message4 = updateById.CityName;
string[] arr = message4.Split(',');

for (int i = 0; i < arr.Length; i++)
{
    foreach (ListItem item in libAdminCity.Items)
    {
       // int j = 0;
       // if (item.Text == arr[i])
        if (libVendorCity.Items.Contains(item))
        {

            //libVendorCity.Items.Add(new ListItem(Convert.ToString(item.Text), Convert.ToString(item.Value)));
            libAdminCity.Items.Remove(item);

        }
        //else
        //{
        //    libVendorCity.Items.Add(new ListItem(Convert.ToString(item.Text), Convert.ToString(item.Value)));
        //}

    }

How you are binding data to your list boxes?

What problem/error you are getting while removing the item from list?

Place a break point and check whether it goes inside the condition.

Your problem seems to be that your Contains() never returns true as it does not exactly what you want. Two items that have the same Text are still two distinct items with regards to this method.

You need to loop over the libVendorCity ListBox and compare each item Text property and if it matches you do the Remove().
