如何获取用于配置文件支持的asp.net匿名身份验证令牌?

在我的Web.config中,我有如下匿名ID设置:

<anonymousIdentification enabled="true" cookieless="AutoDetect" />

我的个人资料部分设置如下:

<profile defaultProvider="SqlProvider" enabled="true" inherits="QA_Web_Tools.UserProfile">
  <providers>
    <clear />
    <add connectionStringName="QAToolsConnectionString" name="SqlProvider"
         type="System.Web.Profile.SqlProfileProvider" />
  </providers>
</profile>

public class UserProfile : ProfileBase
{
    public static UserProfile GetUserProfile(string username)
    {
        return Create(username) as UserProfile;
    }

    public static UserProfile GetUserProfile()
    {
        return Create(Membership.GetUser().UserName) as UserProfile;
    }

    [SettingsAllowAnonymous(true)]
    public string FullName
    {
        get { return base["FullName"] as string; }
        set { base["FullName"] = value; }
    }

    [SettingsAllowAnonymous(true)]
    public string BuildEmail
    {
        get { return base["BuildEmail"] as string; }
        set { base["BuildEvmail"] = value; }
    }
}

this reference .

GetUserProfile() 方法,因为如果用户是匿名的, Membership.GetUser() 为空。我可以把匿名身份令牌传给第一个 GetUserProfile(string username)

有人知道如何获得这些信息吗?谷歌似乎没有返回有用的结果。
