在C#中解析JSON响应

Question

在对api进行查询后,我得到了一个json响应.

JSON就像:

    {
   "results": [
      {
         "alternatives": [
            {
               "confidence": 0.965,
               "transcript": "how do I raise the self esteem of a child in his academic achievement at the same time "
            }
         ],
         "final": true
      },
      {
         "alternatives": [
            {
               "confidence": 0.919,
               "transcript": "it's not me out of ten years of pseudo teaching and helped me realize "
            }
         ],
         "final": true
      },
      {
         "alternatives": [
            {
               "confidence": 0.687,
               "transcript": "is so powerful that it can turn bad morals the good you can turn awful practice and the powerful once they can teams men and transform them into angel "
            }
         ],
         "final": true
      },
      {
         "alternatives": [
            {
               "confidence": 0.278,
               "transcript": "you know if not on purpose Arteaga Williams who got in my mother "
            }
         ],
         "final": true
      },
      {
         "alternatives": [
            {
               "confidence": 0.621,
               "transcript": "for what pink you very much "
            }
         ],
         "final": true
      }
   ],
   "result_index": 0
}

我必须对上面的json结果做两件事(我把它保存为字符串*):

1. 获取json响应的成绩单部分.

2. 处理这些字符串.

   • 我是新来的.转换为字符串仅称为序列化.为什么反序列化有助于此？

转换为字符串:我使用以下方法完成:

 var reader = new StreamReader(response.GetResponseStream());


            responseFromServer = reader.ReadToEnd();

怎么做到这一点？

您可以将JSON解析为具体类,并在以后使用它们.

为此,您可以使用json2csharp之类的服务,该服务根据您提供的JSON生成类.或者,您可以使用Visual Studio内置功能粘贴JSON作为类:

public class Alternative
{
    public double confidence { get; set; }
    public string transcript { get; set; }
}

public class Result
{
    public List<Alternative> alternatives { get; set; }
    public bool final { get; set; }
}

public class RootObject
{
    public List<Result> results { get; set; }
    public int result_index { get; set; }
}

然后,您可以使用JSON.NET将字符串化的JSON解析为具体的类实例:

var root = JsonConvert.DeserializeObject<RootObject>(responseFromServer);
