我是 wcf 和 windows phone 8 应用程序的新手并调用 wcf 服务（其他开发人员）并尝试反序列化数据它有时工作正常但大多数时候它给了我错误

“数据合约类型 'TEST.Model.Response`1[[TEST.Model.Announcement, TEST, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' 无法反序列化，因为成员 'ResponseData' 不是公开。将成员设为公开将修复此错误。或者，您可以将其设为内部，并在程序集上使用 InternalsVisibleToAttribute 属性以启用内部成员的序列化 - 有关更多详细信息，请参阅文档。请注意，这样做具有一定的安全性影响。”

我的模型类是

public class Response<T> where T: class
{
    public string MethodName { get; set; }

    public int ResponseCode { get; set; }

    public string ResponseMessage { get; set; }

    public List<T> ResponseData { get; set; }

}

public class Announcement
{
    public int AnnouncementId { get; set; }

    public string AnnouncementTitle { get; set; }

    public string CreatedBy { get; set; }

    public string CreatedDate { get; set; }

    public string DataShortVersion { get; set; }

    public string ModifiedBy { get; set; }

    public string ModifiedDate { get; set; }

    public int SortIndex { get; set; }
}

当我尝试调用时

var request = ar.AsyncState as WebRequest;
Stream reader = request.EndGetResponse(ar).GetResponseStream(); 

DataContractJsonSerializer jsonSerializer ;\\
jsonSerializer = new DataContractJsonSerializer(typeof(TEST.Model.Response<TEST.Model.Announcement>));
Response<Announcement> objResponse = (Response<Announcement>)jsonSerializer.ReadObject(reader); //error raised

下面的SSCCE代码有效。尝试用您的问题自己创建一个，看看它与下面的问题有何不同。这可能会引导您找到答案。
