Question

我将以下JSON发送到接受Stream作为参数的WCF服务。

{"ReservationStream":
{"clientFirstName":"Abe",
"clientLastName":"Lincoln",
"clientPhone":"0544944860",
"clientEmail":"abe@mail.com",
"pickupLocationID":"3699",
"pickupAddressString":"JFK Airport Terminal 1",
"pickupFlightNumber":"LY001",
"pickupAirline":"El Al",
"pickupAirportName":"John F Kennedy Intl",
}
}

在调试器中，stream变量按预期显示所有值。我想反序列化为如下定义的类：

public class ReservationStream
{
        public String clientFirstName { get; set; }
        public String clientLastName { get; set; }
        public String clientPhone { get; set; }
        public String clientEmail { get; set; }
        public String pickupLocationID { get; set; }
        public String pickupAddressString { get; set; }
        public String pickupFlightNumber { get; set; }
        public String pickupAirline { get; set; }
        public String pickupAirportName { get; set; }
}

当我打电话

 JavaScriptSerializer javaScriptSerializer = new JavaScriptSerializer();
            ReservationStream structuredReservations = javaScriptSerializer.Deserialize<ReservationStream>(strJSON);

不会抛出任何异常，但所有字段都具有空值。我的错误在哪里？

Answer 1

我认为这是因为您的JSON对象嵌套在ReservationStream标记内。

尝试使用：

{ "clientFirstName":"Abe", "clientLastName":"Lincoln", "clientPhone":"0544944860", "clientEmail":"abe@mail.com", "pickupLocationID":"3699", "pickupAddressString":"JFK Airport Terminal 1", "pickupFlightNumber":"LY001", "pickupAirline":"El Al", "pickupAirportName":"John F Kennedy Intl" }

Answer 2

您尝试反序列化包含 ReservationStream对象的对象而不是ReservationStream对象本身。

解决这个问题的一种方法是创建一个包含ReservationStream的包装类并使用它反序列化：

public class WrapperClass
{
    public ReservationStream ReservationStream { get; set; }
}

WrapperClass wrapperClass = serializer.Deserialize<WrapperClass>(strJSON);

我曾经遇到同样的问题，我删除了javaScriptSerializer并直接使用了像这样的方法参数

public static string UpdateTemplateProperties(TemplateProperties templateProperties)
{
    var x = templateProperties.Something
}

我有

的javascript对象结构

确保参数名称与javascript对象文字中的第一个对象名称相同

JavaScriptSerializer.Deserialize提供空字段
