c# - 读取 JSON 文件并映射到 C# 对象

Question

我想读取一个 JSON 文件并将其映射到类对象。我将如何在 C# 中执行此操作？

JSON

{  
   "companyName":"Test company",
   "companyNumber":"1234",
   "address":{  
      "buildingNumber":"33",
      "street":"Caledon Road",
      "county":"Barking and Dagenham",
      "postalTown":"Essex",
      "postcode":"E62HE"
   }
}

C#代码

public class CompanyInfo
{ 
    public string companyName{ get;set;}
    public string companyNumber{ get;set;}
    public string buildingNumber{ get;set;}
    public string street{ get;set;}
    public string county{ get;set;}
    public string postalTown{ get;set;}
    public string postCode{ get;set;}
}

Answer 1

编写代码

    var json = {  
                 "companyName":"Test company",
                 "companyNumber":"1234",
                 "address":{  
                     "buildingNumber":"33",
                     "street":"Caledon Road",
                     "county":"Barking and Dagenham",
                     "postalTown":"Essex",
                     "postcode":"E62HE"
                  }
               }

 public class CompanyInfo
    { 
    public string companyName{ get;set;}
    public string companyNumber{ get;set;}
    public Address address {get;set;}
    }

 public class Address
   {
    public string buildingNumber{ get;set;}
    public string street{ get;set;}
    public string county{ get;set;}
    public string postalTown{ get;set;}
    public string postCode{ get;set;}
   }

然后使用Newtonsoft.Json反序列化json

var results = JsonConvert.DeserializeObject<CompanyInfo>(json);
