我正在尝试从在本地 Intranet 上提交 ASP.NET 表单的用户那里获取电子邮件地址。在我的本地机器上测试它时，它工作正常。但是当我发布并开始在生产中测试它时，它不喜欢第 74 行。

这段代码在我的页面加载中仅用于测试目的，因此可以立即获得结果....但它永远不会在生产中加载页面，但在本地机器上的 VS 中调试时工作正常...

IIdentity id = WindowsIdentity.GetCurrent();
        WindowsIdentity winId = id as WindowsIdentity;

        if (id == null) 
        {
            txtDetailedProblem.Text = "Identity is not a windows identity";
            return;
        }

        string userInQuestion = winId.Name.Split('\\')[1];
        string myDomain = winId.Name.Split('\\')[0]; // this is the domain that the user is in
        // the account that this program runs in should be authenticated in there                    
        DirectoryEntry entry = new DirectoryEntry("LDAP://" + myDomain);
        DirectorySearcher adSearcher = new DirectorySearcher(entry);

        adSearcher.SearchScope = SearchScope.Subtree;
        adSearcher.Filter = "(&(objectClass=user)(samaccountname=" + userInQuestion + "))";
        SearchResult userObject = adSearcher.FindOne();

            foreach (string prop in props) 
            {
