How to deserialize json string to object list in c

问题:

I am working with the following JSON string

{
"transactions": 
[
   {
    "paymentcharge":"0.0",
    "amount":352,
    "id":13418,
    "shippingcharge":35,
    "shippingtype":2,
    "status":2,
    "paymenttype":1,
    "date":"2012-10-06 16:15:28.0"
   },   
   {
    "paymentcharge":"0.0",
    "amount":42455,
    "id":16305,
    "shippingcharge":0,
    "shippingtype":2,
    "status":2,
    "paymenttype":2,
    "date":"2012-11-30 09:29:29.0"
   },   
   {
    "paymentcharge":"1.0",
    "amount":42456,
    "id":16305,
    "shippingcharge":0,
    "shippingtype":2,
    "status":2,
    "paymenttype":2,
    "date":"2012-11-30 09:29:29.0"
   }
],
"count":3
}

I have a class structure as follows for parsing and feeling the json data

class clsSalesTran
{
    public double paymentcharge { get; set; }
    public double amount { get; set; }
    public long id { get; set; }
    public int shippingcharge { get; set; }
    public int shippingtype { get; set; }
    public int status { get; set; }
    public int paymenttype { get; set; }
    public DateTime date { get; set; }
}

How can I deserialize the above JSON string into List ?

I am using Newtonsoft.Json for deserialize.

回答1:

first create another class:

public class SalesTransactions
{
     public List<clsSalesTran> transactions {get;set;}
     public int count{get;set;}
}

Then use,

JsonConvert.DeserializeObject<SalesTransactions>(inputString)

回答2:

Create a class as below
By creating the list of class 'clsSalesTran' and a variable for 'Count'

Note: JsonProperty is mandatory from your Json String

public class SalesTransactions
{
     [JsonProperty("transactions")]
     public List<clsSalesTran> transactions {get;set;}
     public int count{get;set;}
}

Then you may use this class as below to deserialize

SalesTransactions st = JsonConvert.DeserializeObject<SalesTransactions>(inputString)

Use the Deserialized object as below

double paymentcharge = st.transactions[0].paymentcharge;

class WeapsCollection
{
    public Dictionary<string, WeaponDetails> Weapons { get; set; }

}

class WeaponList
{
    public WeaponDetails AEK { get; set; }
    public WeaponDetails XM8 { get; set; }
}

class WeaponDetails
{
    public string Name { get; set; }
    public int Kills { get; set; }
    public int Shots_Fired { get; set; }
    public int Shots_Hit { get; set; }
}

class Program  
{
    static void Main(string[] args)
    {
        string json = @"
        {
           'weapons':

                    {
                       'aek':
                            {
                               'name':'AEK-971 Vintovka',
                               'kills':47,
                               'shots_fired':5406,
                               'shots_hit':858
                            },
                       'xm8':
                            {
                               'name':'XM8 Prototype',
                               'kills':133,
                               'shots_fired':10170,
                               'shots_hit':1790
                            },
                    }

        }";

        WeapsCollection weps = JsonConvert.DeserializeObject<WeapsCollection>(json);
        Console.WriteLine(weps.Weapons.First().Value.Shots_Fired);            

        Console.ReadLine();

    }
}
