c# – 我不能得到我的ANID？

我已经添加到WMAppManifest.xml中：

>< Capability Name =“ID_CAP_IDENTITY_DEVICE”/>
>< Capability Name =“ID_CAP_IDENTITY_USER”/>

那么为什么要继续获得空字符串：

public static string GetwindowsLiveAnonymousID()
        {
            int ANIDLength = 32;
            int ANIDOffset = 2;

            string result = string.Empty;
            object anid;
            if (UserExtendedProperties.TryGetValue("ANID",out anid))
            {
                if (anid != null && anid.ToString().Length >= (ANIDLength + ANIDOffset))
                {
                    result = anid.ToString().Substring(ANIDOffset,ANIDLength);
                }
            }

            return result;
        }

它似乎没有处理TryGetValue非常好…有人得到一个线索？

解决方法

It’s called ANID2 in Windows Phone 8.

The UserExtendedProperties API exposes two properties: ANID and ANID2.

• ANID can only be accessed from Windows Phone OS 7.0 and Windows Phone OS 7.1 apps that use the Microsoft Advertising SDK for Windows Phone.

• ANID2 can only be accessed from Windows Phone 8 apps.
