这是一个常规列车服务JSON代码。我想在对象中插入数据。 现在，我正在从一个web服务获取上述格式的数据，并将其输入Win phone 7。 但在尝试解析时，我遇到了一个错误：

using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(_dataString)))
            {
                //parse into jsonser
                var ser = new DataContractJsonSerializer(typeof(MyPersonClass[]));
                MyPersonClass[] obj = (MyPersonClass[])ser.ReadObject(ms);
            }

这是MyPersonClass：

有什么想法吗？

我想你这里有几个问题。首先，您的

MyPersonClass

类型与您给出的json示例的结构不太匹配。如果您将该json字符串插入，它通常会（如果您提供的json字符串包含空值或空数组，它将无法为这些条目提供准确的类型）为您提供解析该字符串所需的类，然后，它将提供给您的

RootObject

类将成为您的

MyPersonClass

第二个问题是，虽然作为示例给出的json字符串只是一个对象，但您告诉DataContractJsonSerializer您希望它反序列化一个对象数组。您可能想要的是：

var ser = new DataContractJsonSerializer(typeof(MyPersonClass)); 
MyPersonClass obj = (MyPersonClass)ser.ReadObject(ms);

---

你能从

MyPerson

类中添加缺少的代码吗？在JSON字符串周围添加方括号后，您提供的代码（在LINQPad中）对我有效。即使没有括号，它也不会抛出异常（只返回一个空数组）。
