Get UPN or email for logged in user in a .NET web application
提问by DrStalker
I'm not a .NET developer, and I have a feeling this would be trivial for someone who is:
我不是 .NET 开发人员，我觉得这对于以下人员来说是微不足道的：
I have a C# web application that makes user of the user credentials of the logged in user. Currently it uses the SID which comes from
我有一个 C# web 应用程序，它使用户使用登录用户的用户凭据。目前它使用来自的 SID
System.Security.Principal.WindowsIdentity.GetCurrent().User.Value
I need to get either the users UPN login or email address (as defined in active directory) instead of the SID. GetCurrent() returns an object of type WindowsIdentity; looking in the details for WindowsIdentity Members:
我需要获取用户 UPN 登录名或电子邮件地址（在活动目录中定义）而不是 SID。GetCurrent() 返回 WindowsIdentity 类型的对象；查看 WindowsIdentity 成员的详细信息：
I can't see anything that looks like it would give me either the UPN or email in there. How can I pull up that information to use, either by feeding the SID into some other function or calling something different in the first place.
我看不到任何看起来会给我 UPN 或电子邮件的内容。我如何提取要使用的信息，或者通过将 SID 提供给其他函数或首先调用不同的东西。

Meanwhile (.NET 3.5) this is a one-liner:
同时（.NET 3.5）这是一个单行：
System.DirectoryServices.AccountManagement.UserPrincipal.Current.EmailAddress
for the email, or
对于电子邮件，或
System.DirectoryServices.AccountManagement.UserPrincipal.Current.UserPrincipalName
for the UPN.
对于 UPN。

To query active directory using a directory searcher you need to do something like this (totally untested code):
要使用目录搜索器查询活动目录，您需要执行以下操作（完全未经测试的代码）：
string userName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
string ldapPath = "LDAP://domain.company.com";
public string GetEmail(string userName, string ldapPath)
{
using (DirectoryEntry root = new DirectoryEntry(ldapPath))
{
DirectorySearcher searcher = new DirectorySearcher(root);
searcher.Filter = string.Format(@"(&(sAMAccountName={0}))", userName);
searcher.PropertiesToLoad = "mail";
SearchResult result = searcher.FindOne();
if (result != null)
{
PropertyValueCollection property = result.Properties["mail"];
return (string)property.Value;
}
else
{
// something bad happened
}
}
}
