Question

响应jtoken我有以下JSON：

https://connect.currencycloud.com/documentation/api-docs/post-beneficiaries-create

{ 
    "details": [ 
    { 
     "payment_type": "regular", 
     "iban": "^[0-9A-Z]{1,34}$", 
     "bic_swift": "^[0-9A-Z]{8}$|^[0-9A-Z]{11}$", 
     "beneficiary_entity_type": "individual" 
    }, 
    { 
     "payment_type": "regular", 
     "iban": "^[0-9A-Z]{1,34}$", 
     "bic_swift": "^[0-9A-Z]{8}$|^[0-9A-Z]{11}$", 
     "beneficiary_entity_type": "company" 
    }, 
    { 
     "payment_type": "priority", 
     "beneficiary_entity_type": "individual", 
     "beneficiary_address": "^.{1,255}", 
     "beneficiary_city": "^.{1,255}", 
     "beneficiary_country": "^[A-z]{2}$", 
     "beneficiary_first_name": "^.{1,255}", 
     "beneficiary_last_name": "^.{1,255}", 
     "iban": "^[0-9A-Z]{1,34}$", 
     "bic_swift": "^[0-9A-Z]{8}$|^[0-9A-Z]{11}$" 
    }, 
    { 
     "payment_type": "priority", 
     "beneficiary_entity_type": "company", 
     "beneficiary_address": "^.{1,255}", 
     "beneficiary_city": "^.{1,255}", 
     "beneficiary_country": "^[A-z]{2}$", 
     "beneficiary_company_name": "^.{1,255}", 
     "iban": "^[0-9A-Z]{1,34}$", 
     "bic_swift": "^[0-9A-Z]{8}$|^[0-9A-Z]{11}$" 
    } 
    ] 
} 

我想从这个数组中检索第三列表..that是

{ 
     "payment_type": "priority", 
     "beneficiary_entity_type": "individual", 
     "beneficiary_address": "^.{1,255}", 
     "beneficiary_city": "^.{1,255}", 
     "beneficiary_country": "^[A-z]{2}$", 
     "beneficiary_first_name": "^.{1,255}", 
     "beneficiary_last_name": "^.{1,255}", 
     "iban": "^[0-9A-Z]{1,34}$", 
     "bic_swift": "^[0-9A-Z]{8}$|^[0-9A-Z]{11}$" 
    }, 

有人请帮我出

Answer 1

可以使用JToken.Load()到JSON加载到内存中，然后使用SelectToken以查询在JSON对象分层结构的对象：

 var root = JToken.Parse(json); 
     var item = root.SelectToken("details[2]"); 

数组索引是基于零的。

更新

要选择对象，例如内部的特定属性"payment_type"，属性的名称添加到现有的查询，和转换为预期类型：

 var payment_type = (string)root.SelectToken("details[2].payment_type"); 

SelectToken支持JSONPath查询语法如下规定：JSONPath - XPath for JSON。
