如何使用LINQ搜索子JSON

Question

我有以下JSON

[
  {
    "id": 1,
    "firstName": "Smith",
    "lastName": "Bill",
    "emails": [
      {
        "id": 1,
        "email": "Bill@Smith.Com",
        "dateCreated": "2017-05-11T10:18:52.3224545-07:00"
      },
      {
        "id": 2,
        "email": "Bill@gmail.com",
        "dateCreated": "2017-05-11T10:20:05.9283127-07:00"
      }
    ]
  },
  {
    "id": 2,
    "firstName": "Bill",
    "lastName": "Smith",
    "emails": []
  }
]

电子邮件模型对象位于此人内部。

我想知道如何使用LINQ语句返回所有拥有与某些输入相匹配的电子邮件的人。例如，如果我搜索＆＃34; Bill@gmail.com" ;,它只会返回

[
      {
        "id": 1,
        "firstName": "Smith",
        "lastName": "Bill",
        "emails": [
          {
            "id": 1,
            "email": "Bill@Smith.Com",
            "dateCreated": "2017-05-11T10:18:52.3224545-07:00"
          },
          {
            "id": 2,
            "email": "Bill@gmail.com",
            "dateCreated": "2017-05-11T10:20:05.9283127-07:00"
          }
        ]
      }  
    ]

应该看起来像下面的内容？

var personWithEmail = People.FirstOrDefault(e => e.Id == i);

除了这只是找到有ID的人，而我想深入查看他们孩子的电子邮件并搜索电子邮件是否匹配。
