在 .NET Web 应用程序中获取登录用户的 UPN 或电子邮件

问题描述

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:

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

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

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() 返回一个类型为 WindowsIdentity 的对象；查看 WindowsIdentity 成员的详细信息:

MSDN:WindowsIdentity 成员

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 提供给其他一些函数，或者首先调用不同的东西.

同时 (.NET 3.5) 这是一个单行:

System.DirectoryServices.AccountManagement.UserPrincipal.Current.EmailAddress

用于电子邮件，或

System.DirectoryServices.AccountManagement.UserPrincipal.Current.UserPrincipalName

用于 UPN.

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

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 

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: WindowsIdentity Members

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.

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

System.DirectoryServices.AccountManagement.UserPrincipal.Current.EmailAddress

for the email, or

System.DirectoryServices.AccountManagement.UserPrincipal.Current.UserPrincipalName

for the UPN.
