Question

如果我想从下面的示例中删除一个Json对象，该怎么办？

{ Name : "abc",
  EMail : "abc@gmail.com"
  Fruits : [{
    Name : "name",
    family: "Z"
},
{
    Name : "name",
    family: "A"
},
{
    Name : "name",
    family: "B"
},
{
    Name : "name",
    family: "C"
}
]
}

如果我想删除{ Name : "name", family: "C" }，请从上面的示例中获取。我知道家庭= C并且它是独一无二的。
