如何使用ling to json查询过滤json数据

Question

我是json的新手。我必须在c#中使用linq到json查询过滤json数据。我必须从以下示例json数据中检索多个值:

{
    "parts": [
    {
      "attributes": {
        "Motherboard": "Gigabyte GA-H81M-S2H",
        "Max RAM": "16GB",
        "Form Factor": "Micro ATX",
        "RAM Slots": 2,
        "Socket / CPU": "LGA1150"
      },
      "type": "Motherboard",
      "name": "Gigabyte GA-H81M-S2H",
      "slug": "gigabyte-motherboard-gah81ms2h"
    },
    {
        "attributes": {
        "Motherboard": "MSI H55-G43",
        "Max RAM": "16GB",
        "Form Factor": "ATX",
        "RAM Slots": 4,
        "Socket / CPU": "LGA1156"
      },
      "type": "Motherboard",
      "name": "MSI H55-G43",
      "slug": "msi-motherboard-h55g43"
    },
    {
      "url": "http://pcpartpicker.com/part/asus-motherboard-rampageivblackedition",
      "attributes": {
        "Motherboard": "Asus Rampage IV Black Edition",
        "Max RAM": "128GB",
        "Form Factor": "EATX",
        "RAM Slots": 8,
        "Socket / CPU": "LGA2011"
      },
      "type": "Motherboard",
      "name": "Asus Rampage IV Black Edition",
      "slug": "asus-motherboard-rampageivblackedition"
    }
 ],
}

请帮助我查询如何使用where子句选择多个(键，值)。我必须使用where子句选择名称，段码，形状因子，主板。

首先需要创建与JSON内容结构相关的类。这个免费的在线工具可以帮助您轻松地从JSON数据创建c#类。然后你需要将这个JSON解析为一个c#类的对象。

之后，您可以在此object上执行LINQ操作，过滤它们并根据需要解析回JSON。

可以使用Json。. NET中所有序列化和反序列化操作。
