C＃ - 不确定如何修复与其他人复制的自定义类/类型有关的错误

Question

我正在尝试从Active Directory获取动态发行组的列表，有人指向我堆栈溢出链接使用据说有效的代码，但我不是100％确定如何使该代码的所有部分都起作用，因为该链接仅包含其代码的一部分。我在底部添加了几个使用的语句和几个结构和几个结构和发行列表类，但是我不确定如何摆脱设置的错误。ImpersonatedUserDomain Line抛出的抛出，因为它说“模糊的使用域”并未在'设置'。我也遇到了麻烦

dl.dtype = new dlt.ddl.set（）;

因为它说“ ddl”的类型名称在类型的'class2.dlt'中不存在，即使我已经在下面的结构中定义了它。我不确定我在这里做错了什么。我会评论堆栈溢出问题，但我没有足够的声誉。谁能帮忙？
