我需要以编程方式找到用户名称使用C＃。具体而言，我想获得附加到当前进程的系统/网络用户。我在写一个使用Windows集成安全性的Web应用程序。

I need to programatically find the users name using C#. Specifically, I want to get the system/network user attached to the current process. I'm writing a web application that uses windows integrated security.

推荐答案

身份的抽象看法往往是的IPrincipal / 的IIdentity ：

The abstracted view of identity is often the IPrincipal/IIdentity:

IPrincipal principal = Thread.CurrentPrincipal; IIdentity identity = principal == null ? null : principal.Identity; string name = identity == null ? "" : identity.Name;

这允许同一code在许多不同的模式（的winform，asp，WCF等）的工作 - 但它依赖于身份被预先设置（因为它是应用程序定义）。例如，在一个WinForm你可能会使用当前用户的Windows身份：

This allows the same code to work in many different models (winform, asp, wcf, etc) - but it relies on the identity being set in advance (since it is application-defined). For example, in a winform you might use the current user's windows identity:

Thread.CurrentPrincipal = new WindowsPrincipal(WindowsIdentity.GetCurrent());

不过，校长也可以完全定制 - 它并不一定涉及到Windows帐户等。另一个应用程序可能会使用一个登录界面，允许任意用户登录：

However, the principal can also be completely bespoke - it doesn't necessarily relate to windows accounts etc. Another app might use a login screen to allow arbitrary users to log on:

string userName = "Fred"; // todo string[] roles = { "User", "Admin" }; // todo Thread.CurrentPrincipal = new GenericPrincipal(new GenericIdentity(userName), roles);
