获取JSON数据并将其转换为C＃中的类

Question

Hi i would like to convert some json data into an instance of ac# class :

for example if i have this json code :

"product": [                            
  { 
    "CarBrand": [ 
        "HippoCars", 
        "CondorTrucks", 
        "CheetahMotors"                  
    ], 
    "CarCategory": [ 
        "truck", 
        "car", 
        "MotorBike"

And the class :

   public class Catalogue
{
    public List<Product> product { get; set; }
 public List<string> CarBrand { get; set; }
    public List<string> CarCategory { get; set; }
}

How can I convert the JSON data into the c# class?

Answer 1

你可以尝试使用

var mydata = JsonConvert.DeserializeObject<Catalogue>(jsonString);

Answer 2

First, your JSON is not correct. This is correct:

{ 
"product": [                              <--- double quotes
  { 
    "CarBrand": [ 
        "HippoCars", 
        "CondorTrucks", 
        "CheetahMotors"                   <---- no trailing comma
    ], 
    "CarCategory": [ 
        "truck", 
        "car", 
        "MotorBike"
    ]
  }                                       <----- closing object curly brackets
]                                         <----- closing array square brackets
}                                         <----- final }

Then you need to have two classes, not one:

public class Catalogue
{
    public List<Product> product { get; set; }
}

public class Product
{
    public List<string> CarBrand { get; set; }
    public List<string> CarCategory { get; set; }
}

Only than you can use Json.NET as other suggested or

Catalogue catalogue = new JavaScriptSerializer().Deserialize<Catalogue>(jsonString);
