推荐答案

将身份验证更改为"Windows身份验证"(如何-到)

不使用电流，而是分两个步骤进行:(源)

Instead of using current, doing it in two steps: (source)

PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

UserPrincipal user = UserPrincipal.FindByIdentity(ctx, User.Identity.Name);

为了最终获得名称(或其他信息)，我使用了user.DisplayName.

And to finally get the name (or any other info), I used user.DisplayName.
