使用ReadAsAsync< T>（）反序列化复杂的Json对象 [英] Using ReadAsAsync<T>() to deserialize complex Json object

问题描述

我想在带有.net 4.0的mvc项目中使用ReadAsAsync（）。结果为空。

I want to use ReadAsAsync() in my mvc project with .net 4.0. The result comes as null.

如果我输入uri到地址栏，则以chrome as（标记名已更改）为结果。

If I enter the uri to address bar, the result in chrome as(tag names are changed):

<ns2:MyListResponse xmlns:ns2="blablabla">
  <customerSessionId>xxcustomerSessionIdxx</customerSessionId>
  <numberOfRecordsRequested>0</numberOfRecordsRequested>
  <moreResultsAvailable>false</moreResultsAvailable>
  <MyList size="1" activePropertyCount="1">
    <MySummary order="0">
      <id>1234</id>
      <name>...</name>
      .
      .   
    </MySummary>
  </MyList>
</ns2:MyListResponse>

如果我在代码中使用以下语句：

If I use the statement in code :

using (var client = new HttpClient())
{
     var response = client.GetAsync(apiUri).Result;
     var message = response.Content.ReadAsStringAsync().Result;

     var result1 = JsonConvert.DeserializeObject<MyListResponse>(message);
     var result2 = response.Content.ReadAsAsync<MyListResponse>().Result;
}

消息以字符串格式显示为 {＼ ＼ MyListResponse\：{\ customerSessionId\ ...} 对应于一个json对象，如下：

the message comes in string format as "{\"MyListResponse\":{\"customerSessionId\"...}" which corresponds to a json object as:

{"MyListResponse":
    {"customerSessionId":"xxcustomerSessionIdxx",
     "numberOfRecordsRequested":0,
     "moreResultsAvailable":false,
     "MyList":
        {"@size":"1",
         "@activePropertyCount":"1",
         "MySummary":
            {"@order":"0",
             "id":1234,
             "name":"...",
             .
             .
            }
        }
    }
 } 

，result1和result2的属性为null或默认值。类定义如下。我想将内容作为对象读取，但不能。您对解决这个问题有何建议？我究竟做错了什么？

and the properties of result1 and result2 came as null or default values. Class definitions are below. I want to read the content as an object but I couldn't. What do you advice to solve this? What am I doing wrong? Thanks in advance.

public class MySummary
{
    public int @Order { get; set; }
    public string Id { get; set; }
    public string Name { get; set; }
    .
    .
}

public class MyList
{
    public int @Size { get; set; }
    public int @ActivePropertyCount { get; set; }
    public MySummary MySummary{ get; set; }
}

public class MyListResponse
{
    public string CustomerSessionId { get; set; }
    public int NumberOfRecordsRequested { get; set; }
    public bool MoreResultsAvailable { get; set; }
    public MyList MyList { get; set; }
}

推荐答案

我定义了一个新类如：

public class ResponseWrapper
{
    public MyListResponse MyListResponse { get; set; }
}

然后我将此包装与

 var result1 = JsonConvert.DeserializeObject<ResponseWrapper>(message);
 var result2 = response.Content.ReadAsAsync<ResponseWrapper>().Result;

然后它起作用了。我只需要MySummary对象，但我应该编写更多的类来使其工作。

then it worked. I need only MySummary object but I should write more classes to make it work.
