无法将类型'system.collections.generic.list <string>'隐式转换为'string'

Question

我创建了一个类，其中包含一种方法来显示AD中所选用户的属性。当我尝试调用此方法将所有对象放入列表视图时，出现错误。

感谢您的帮助

class ProgramDisplayObjAD
{
    public static List<string> ComputersDisAD(string SelectedObjAD)
    {
        List<string> ComputerNamesList = new List<string>();

        DirectoryEntry DirEntry = new DirectoryEntry("LDAP://OU=Backoffice,OU=BIO,DC=bio,DC=corpnet1,DC=com");
        DirectorySearcher MySearcher = new DirectorySearcher(DirEntry);

        MySearcher.Filter = "(&(objectCategory=computer)(cn=" + SelectedObjAD + "))";

        foreach (SearchResult MyResult in MySearcher.FindAll())
        {
            DirectoryEntry ComputerName = MyResult.GetDirectoryEntry();

            Console.WriteLine("Computername : " + ComputerName.Properties["dNSHostName"].Value);
            Console.WriteLine("Staging Date : " + ComputerName.Properties["whenCreated"].Value);
            Console.WriteLine("Operating System : " + ComputerName.Properties["operatingSystem"].Value);
        }

        DirEntry.Close();
        DirEntry.Dispose();
        MySearcher.Dispose();

        return ComputerNamesList;
    }

private void ListObjAD_DoubleClick(object sender, EventArgs e)
    {
        string SelectedObjAD = ListObjAD.SelectedItem.ToString();

        if (ComputerName.Checked)
        {
            ComputerPage.Text = SelectedObjAD;

            DisplayObjAD.SelectedTab = ComputerPage;

            //List<string> ComputersList = ProgramDisplayObjAD.ComputersDisAD(SelectedObjAD);

            ComputerItemList.Items.Add(new ListViewItem(new string[] { ProgramDisplayObjAD.ComputersDisAD(SelectedObjAD) };
        }

我知道该方法可以正常工作，但是我不知道如何在我的listviewitem中显示结果：ComputerListDis。
