【问题描述】：

如何在 c# 中提取这些数据，以便获取我需要的所有元素：

 "id": "PAY-6A414645MC669653MKPB2WCI", "create_time": "2014-07-14T10:03:53Z", "update_time": "2014-07-14T10:05:09Z", "intent": "sale", "payer":  "payment_method": "paypal", "payer_info":  "email": "[e-mail]", "first_name": "tester", "last_name": "tester", "payer_id": "MSQ6UB55W52N6", "shipping_address":  "line1": "1 Main Terrace", "line2": "", "city": "Wolverhampton", "country_code": "GB", "postal_code": "W12 4LQ", "state": "West Midlands"   , "transactions": [  "amount":  "currency": "EUR", "total": "54.00", "details":  "subtotal": "54.00"  , "description": "Transaction Description", "item_list":  "items": [  "quantity": "1", "name": "Project Submission (featured)", "price": "54.00", "currency": "EUR", "sku": "64866"  ], "shipping_address":  "recipient_name": "tester tester", "line1": "1 Main Terrace", "line2": "", "city": "Wolverhampton", "country_code": "GB", "postal_code": "W12 4LQ", "state": "West Midlands"  , "related_resources": [  "sale":  "id": "4VV61663EL511901P", "create_time": "2014-07-14T10:03:53Z", "update_time": "2014-07-14T10:05:09Z", "amount":  "currency": "EUR", "total": "54.00" , "state": "pending", "parent_payment": "PAY-6A414645MC669653MKPB2WCI", "links": [  "href": "https://api.sandbox.paypal.com/v1/payments/sale/4VV61663EL511901P", "rel": "self", "method": "GET" ,  "href": "https://api.sandbox.paypal.com/v1/payments/sale/4VV61663EL511901P/refund", "rel": "refund", "method": "POST" ,  "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-6A414645MC669653MKPB2WCI", "rel": "parent_payment", "method": "GET"  ]   ]  ], "state": "pending", "links": [  "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-6A414645MC669653MKPB2WCI", "rel": "self", "method": "GET"  ] 

我尝试发送到 jquery 函数但没有成功。

我也试过这个：

JObject.Parse(HttpContext.Current.Items["ResponseJson"]).GetValue("id");

这有效，但仅适用于一个值，而不是我想要的全部

【参考方案1】：

你必须像这样声明类

public class Rootobject

    public string id  get; set; 
    public DateTime create_time  get; set; 
    public DateTime update_time  get; set; 
    public string intent  get; set; 
    public Payer payer  get; set; 
    public Transaction[] transactions  get; set; 
    public string state  get; set; 
    public Link1[] links  get; set; 


public class Payer

    public string payment_method  get; set; 
    public Payer_Info payer_info  get; set; 


public class Payer_Info

    public string email  get; set; 
    public string first_name  get; set; 
    public string last_name  get; set; 
    public string payer_id  get; set; 
    public Shipping_Address shipping_address  get; set; 


public class Shipping_Address

    public string line1  get; set; 
    public string line2  get; set; 
    public string city  get; set; 
    public string country_code  get; set; 
    public string postal_code  get; set; 
    public string state  get; set; 


public class Transaction

    public Amount amount  get; set; 
    public string description  get; set; 
    public Item_List item_list  get; set; 
    public Related_Resources[] related_resources  get; set; 


public class Amount

    public string currency  get; set; 
    public string total  get; set; 
    public Details details  get; set; 


public class Details

    public string subtotal  get; set; 


public class Item_List

    public Item[] items  get; set; 
    public Shipping_Address1 shipping_address  get; set; 


public class Shipping_Address1

    public string recipient_name  get; set; 
    public string line1  get; set; 
    public string line2  get; set; 
    public string city  get; set; 
    public string country_code  get; set; 
    public string postal_code  get; set; 
    public string state  get; set; 


public class Item

    public string quantity  get; set; 
    public string name  get; set; 
    public string price  get; set; 
    public string currency  get; set; 
    public string sku  get; set; 


public class Related_Resources

    public Sale sale  get; set; 


public class Sale

    public string id  get; set; 
    public DateTime create_time  get; set; 
    public DateTime update_time  get; set; 
    public Amount1 amount  get; set; 
    public string state  get; set; 
    public string parent_payment  get; set; 
    public Link[] links  get; set; 


public class Amount1

    public string currency  get; set; 
    public string total  get; set; 


public class Link

    public string href  get; set; 
    public string rel  get; set; 
    public string method  get; set; 


public class Link1

    public string href  get; set; 
    public string rel  get; set; 
    public string method  get; set; 

那么你必须使用using Newtonsoft.Json; 来表示DeserializeObject 之类的

 var Data = JsonConvert.DeserializeObject<Rootobject>("your Json string");

您可以使用Data访问该属性

O/P 看起来像

【参考方案2】：

你只需要制作一个映射对象，然后反序列化 json

public class PaymentResponse

    public string id  get; set; 
    public DateTime create_time  get; set; 
    public DateTime update_time  get; set; 
    public string intent get; set; 
    public Payer payerget; set; 



public class Payer


    public string payment_method get;set;
    public PayerInfo payer_info get;set;



public class PayerInfo

    public string email  get; set; 
    public string first_name  get; set; 

没有时间添加所有值，但如果您使用 json 解析器，您可以更轻松地查看响应。我更喜欢这个。

然后简单地用下面的反序列化 json 响应

var paymentResponse = new javascriptSerializer().Deserialize<PaymentResponse>(jsonString);
