XMLSerializer不寫入列表中的元素

我正在編寫一個程序，該程序基本上會爲本地計算機SAM存儲中的用戶提供大部分內容的xml副本。XMLSerializer不寫入列表中的元素

目前它只爲每個用戶打印一個XMLElement，但不打印它們的屬性。

<?xml version="1.0" encoding="utf-8"?> 
<WindowsUserList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <windowsUserEntry /> 
    <windowsUserEntry /> 
    ... 
    <windowsUserEntry /> 
    <windowsUserEntry /> 
</WindowsUserList>

這是我的主要代碼，該複選框文本已用於搜索作爲其文本格式的名稱（會計*例如讓用戶accounting1，2，3等..）

windowsUserList listUsers = new windowsUserList(); 
PrincipalContext context = new PrincipalContext(ContextType.Machine, Settings.Default.ipAddress, Settings.Default.username, Settings.Default.password); 
foreach (CheckBox cbx in groupBox1.Controls.OfType<CheckBox>()) 
{ 
    if (cbx.Checked) 
    { 
    UserPrincipal usr = new UserPrincipal(context); 
    if (cbx.Text == "") 
    { 
     usr.Name = txtCustom.Text; 
    } 
    else 
    { 
     usr.Name = cbx.Text; 
    } 
    PrincipalSearcher search = new PrincipalSearcher(usr); 
    PrincipalSearchResult<Principal> results = search.FindAll(); 
    foreach (Principal result in results) 
    { 
     listUsers.AddUser(new windowsUserEntry((UserPrincipal)result)); 
    } // foreach (Principal result in results) 
    }//if (cbx.Checked) 
}//foreach (CheckBox cbx in groupBox1.Controls.OfType<CheckBox>()) 
XmlSerializer s = new XmlSerializer(typeof(windowsUserList)); 
TextWriter w = new StreamWriter(dlgSave.OpenFile()); 
s.Serialize(w, listUsers); 
w.Close();

Windows用戶列表/條目的代碼非常長，所以我將其發佈到pastebin
