获取UPN或电子邮件进行登录的用户在.NET Web应用程序 [英] Get UPN or email for logged in user in a .NET web application

问题描述

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:

<一个href="http://msdn.microsoft.com/en-us/library/system.security.principal.windowsidentity%5Fmembers.aspx">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.
