Active Directory如何用Ｃ#進行增加、刪除、修改、查詢用戶與組織單位

首先我們來了解一下什麼是Active Directory。不用我描述，看以下網址，或在.Net自帶幫助文檔裡根據Active Directory關鍵字一搜，就什麼都明白了。

接下來，我們來看看權限。你可以通過“網上鄰居--整個網絡--Directory--demain(你的域名)”你就可以看到所有關於域下的信息，粗一看就知道是怎麼回事了。
需要告訴大家的：所有組織單位下的用戶都在Users(容器)--Demain Users(組)中
用代碼進行訪問時，如果你是域管理員用戶，則可以做任何操作，否則，只能查詢用戶屬性。

private void SearchUser()
{
string domainName = "Domain";
string groupName = "Domain Users";
string dirmemName="";
//在Domain Users域用戶裡取得每個用戶名
System.DirectoryServices.DirectoryEntry group = new System.DirectoryServices.DirectoryEntry("WinNT://" + domainName + "/" + groupName + ",group");
foreach(Object member in (IEnumerable)group.Invoke("Members"))
{
//根據很個用戶生成如："LDAP://OU=套裝軟體課,OU=系統開發部,OU=資訊服務處,OU=營運支援中心,OU=XX公司,DC=Domain,DC=com,DC=cn"
System.DirectoryServices.DirectoryEntry dirmem = new System.DirectoryServices.DirectoryEntry(member);
dirmemName=dirmem.Name;
string DomainName="Domain";
string FilterStr = "(sAMaccountname="+dirmemName+")";
System.DirectoryServices.DirectorySearcher FindMe = new System.DirectoryServices.DirectorySearcher(DomainName);
FindMe.Filter = FilterStr;
System.DirectoryServices.SearchResult FindRes = FindMe.FindOne();
System.DirectoryServices.DirectoryEntry MyUser = FindRes.GetDirectoryEntry();
string OUPath=MyUser.Parent.Path;
//找到該用戶所在的LDAP:後，由域管理員登錄，並取得該用戶的所在屬性。
string strFieldsValue="",strFIElds="";
System.DirectoryServices.DirectoryEntry myds=new System.DirectoryServices.DirectoryEntry(OUPath,"域管理員名","域管理員密碼");
foreach(System.DirectoryServices.DirectoryEntry tempEntry in myds.Children)
{
if(tempEntry.ScheMaclassName.ToString() == "user" && tempEntry.PropertIEs["sAMaccountName"].Value.ToString().ToLower()==dirmemName)
{
foreach (string propertyName in tempEntry.PropertIEs.PropertyNames )
{
string oneNode = propertyName + ": " +
entry.PropertIEs[propertyName][0].ToString();
this.Textbox1.Text=oneNode;
}
}

public void AddUser(string strPath,string Username,string ChineseName)//strPath 增加用戶至哪個組織單位如"LDAP://OU=XX公司,DC=Domain,DC=com"帳號、中文名{
