Question

我需要访问我的用户的UserId，所以我想这可以通过扩展user.shared和AuthenticationService来完成。我的目标是在客户端访问UserId（这是一个“Guid”），默认情况下这是不可能的。

@ User.shared我添加了这些行：

/// <summary>
/// Gets the UserId of the user.
/// </summary>
public Guid UserId { get; private set; }

这里是AuthenticationService类 - 我需要在这里插入什么才能返回UserId ??

[EnableClientAccess]
public class AuthenticationService : AuthenticationBase<User> 
{ 
    //adapt GetAuthenticatdUser in order to be able to retrieve the UserId @ the client !
    protected override User GetAuthenticatedUser(System.Security.Principal.IPrincipal principal)
    {

        return base.GetAuthenticatedUser(principal);
        //what does this line above actually do ?!!?

        //INSERT statement which returns the UserId (Guid)
    }
}

对你们所有人来说，THX已经在这个话题上已经失去了至少1个小时： - （。

如果您查看Silverlight业务应用程序模板，则会有一个名为FriendlyName的UserProfile。你可以在配置文件中填充Guid。

Answer 2

嗯...是的，我可以找到FriendlyName，它返回一个字符串。但是，我真的不明白这对用户ID有何帮助？在这里我能找到：

 public partial class User
    {
        /// <summary>
        /// Returns the user display name, which by default is its FriendlyName.
        /// If FriendlyName is not set, the User Name is returned.
        /// </summary>
        public string DisplayName
        {
            get
            {
                if (!string.IsNullOrEmpty(this.FriendlyName))
                {
                    return this.FriendlyName;
                }
                else
                {
                    return this.Name;
                }
            }
        }

        /// <summary>
        /// Gets the UserId of the user.
        /// </summary>
        public Guid UsrId { get; private set; } //I added this line
        //this doesnt really work yet - don't know how to access the actual guid :-(
    }



/// <summary>
    /// Class containing information about the authenticated user.
    /// </summary>
    public partial class User : UserBase
    {
        //// NOTE: Profile properties can be added for use in Silverlight application.
        //// To enable profiles, edit the appropriate section of web.config file.
        ////
        //// public string MyProfileProperty { get; set; }

        /// <summary>
        /// Gets and sets the friendly name of the user.
        /// </summary>
        public string FriendlyName { get; set; }


    }

Web.config只包含：

<properties>
        <add name="FriendlyName" />
      </properties>

Silverlight - 扩展用户（或AuthenticationService）
