C#MVC新Active Directory用户System.DirectoryServices.AccountManagement.PrincipalOperationException:服务器上没有此类对象

有5个或6个类似的线程，但都不是这个问题的解决方案。似乎当我尝试为新用户帐户创建新的主要用户时。。。它似乎正在搜索服务器上不存在的帐户。我发布了我所有的代码，在网上找到的各种版本的解决方案似乎都没有被注释掉（即，最后一部分，也是唯一未注释的部分，是让我在过程中走得最远并产生此错误的代码）。。。我已经做了三天了：

     string admin_password = "Password!";

     for (int i = 0; i < 3; i++) {
         try {
             UserPrincipal up = new UserPrincipal(ouContex);
             up.SamAccountName = "Administrator" + i;
             up.SetPassword("Password!");

您能显示哪一行抛出PrincipalOperationException吗？似乎应该检查

PrincipalContext

用法。更新信息。我觉得我已经尝试了每一个论点的每一个组合。
