我不是一个.NET开发人员，我有一种感觉，这将是微不足道的人谁是：

I'm not a .NET developer, and I have a feeling this would be trivial for someone who is:

我有一个C＃的Web应用程序，使得已登录用户的用户凭据的用户。目前它使用它来自该SID

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

System.Security.Principal.WindowsIdentity.GetCurrent().User.Value

我需要得到的，而不是SID无论是用户UPN账号或电子邮件地址（如Active Directory中定义）。 GetCurrent（）返回一个类型的WindowsIdentity的对象;看在细节的WindowsIdentity成员：

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:

MSDN:的WindowsIdentity成员

我看不到任何东西，看起来像它会给我无论是UPN或电子邮件在那里。我怎么能拉起来的信息的使用，无论是喂SID转换成一些其他的功能，或调用的东西摆在首位的不同。

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.

推荐答案

同时（.NET 3.5），这是一个班轮：

Meanwhile (.NET 3.5) this is a one-liner:

System.DirectoryServices.AccountManagement.UserPrincipal.Current.EmailAddress

有关的电子邮件，或

System.DirectoryServices.AccountManagement.UserPrincipal.Current.UserPrincipalName

的UPN。
