操作windows帐户的方法的诀窍在于通过DirectoryEntry 实例调用Invoke，InvokeGet,InvokeSet这三个方法。此三个方法可以对对本机 Active Directory 对象调用方法。操作win帐户的Active Directory 对象就是IADsUser接口。DirectoryEntry 实例通过调用Invoke方法调用IADsUser接口的方法，如上面修改Windows帐户密码就是通过调用IADsUser接口的“ChangePassword”方法；通过InvokeGet和InvokeSet方法调用IADsUser接口的属性，如上面的启用/禁用windows帐户，调用IADsUser接口的“AccountDisabled”属性
