错误＆＃34;无效的JSON原语＆＃34;反序列化？

我正在序列化对象以使其从WebAPI返回。

下面的代码从DB获取数据并序列化对象：

public string GetHealthInsuranceApplication(int PId)
    {  
        HealthApplicationViewModel model = new HealthApplicationViewModel();
        model.ProductDetails.Category = StringResources.ProductCategoryFamily;
        model.Tab = HealthLeadTab.YourDetails;
        model.ProductDetails = db.CurrentProductSetRepository.GetByID(PId);
        string data = new JavaScriptSerializer().Serialize(model);                
        return data;                   
    }          
}

这是我的序列化字符串：

当我尝试使用下面的代码对其进行反序列化时，会生成错误“Invalid Json primitive”：

 public static T GetObjectFromSerializedJSONString<T>(string data)
         where T : class, new()
    {
        T obj = new T();

        if (!string.IsNullOrEmpty(data) && data !="null")
        {
            JavaScriptSerializer jsSerObj1 = new JavaScriptSerializer();
            jsSerObj1.MaxJsonLength=int.MaxValue;
            data =jsSerObj1.Deserialize<string>(data);
            JavaScriptSerializer jsSerObj2 = new JavaScriptSerializer();
            jsSerObj2.MaxJsonLength = int.MaxValue;
            obj =jsSerObj2.Deserialize<T>(data);
        }            

        return obj;
    }

修改 1.在序列化obj（用于测试）后，我使用下面的行来反序列化，我能够反序列化而不会出现错误new JavaScriptSerializer().Deserialize<HealthApplicationViewModel>(data);

  1. 当尝试在调用WebAPI的类中使用相同的代码行时，我得到相同的错误“无效的JSON原语”

    2. 请帮助我。

不是有效的JSON，会导致问题。

我解决了这个问题。我刚刚检查过，我的WebClient将它作为XML返回，所以我修改了它并从那里以Json的形式返回，之后就好了。
