我有一个我要解析的VCard字符串并插入手机的联系人商店。 我查看了此链接http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj207024(v=vs.105).aspx#BKMK_UsingtheRemoteIdHelperclass
并找到以下方法
ContactInformation info = await ContactInformation.ParseVcardAsync(IInputStream vcard);
如何将我的VCard字符串转换为IInputStream以便我可以解析它？

好的，我发现了这个：
我们将使用 WindowsRuntimeStreamExtensions 类将 System.IO Streams 转换为 Windows.Storage.Streams 对象：
System.IO.MemoryStream ms = new System.IO.MemoryStream(System.Text.Encoding.UTF8.GetBytes(VCardDataString));
IInputStream input= System.IO.WindowsRuntimeStreamExtensions.AsInputStream(ms);
ContactInformation info = await ContactInformation.ParseVcardAsync(input);
StoredContact phoneContact = new StoredContact(store, info);
