推荐答案

如果您使用的是.Net 3.0或更高版本，那么有一个可爱的库实际上可以使之写自己。 System.DirectoryServices.AccountManagement 有一个 UserPrincipal 对象，它可以准确地获取您要查找的内容，而您不必与LDAP混为一谈或掉到系统调用中去做。

If you're using .Net 3.0 or higher, there's a lovely library that makes this practically write itself. System.DirectoryServices.AccountManagement has a UserPrincipal object that gets exactly what you are looking for and you don't have to mess with LDAP or drop to system calls to do it. Here's all it'd take:

Thread.GetDomain().SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsPrincipal principal = (WindowsPrincipal)Thread.CurrentPrincipal;
// or, if you're in Asp.Net with windows authentication you can use:
// WindowsPrincipal principal = (WindowsPrincipal)User;
using (PrincipalContext pc = new PrincipalContext(ContextType.Domain))
{
    UserPrincipal up = UserPrincipal.FindByIdentity(pc, principal.Identity.Name);
    return up.DisplayName;
    // or return up.GivenName + " " + up.Surname;
}

注意：如果您已经有用户名，则实际上不需要主体，但是如果您是在用户上下文下运行，那么从那里拉它就很容易。

Note: you don't actually need the principal if you already have the username, but if you're running under the users context, it's just as easy to pull it from there.
