Hi sir,
we are use windows application and GetSelectedIndices() this method in web

Here is the code for Windows Forms;

  string s = "";
            foreach (object item in listBox1.SelectedItems) {
                s = s+" "+ item.ToString();
            }
            label1.Text = s;
           

======
That previous code was for webapplication. So it gave error missing assembly reference.

Try this code.

You can try this code.

 string s = "";
        foreach (ListItem li in ListBox1.Items) {

            if (li.Selected == true) {
                s = s +" "+ li.Value;
            }

        }
