如何合并/组合 2 个 json 数组

Question

所以我在下面的变量中有 2 个 json 数组作为字符串。他们都有标题“发票”，我想将两者合并在一起，所以里面只有 1 个标题和 4 个项目。

目前有：

var info1 = {"invoices":[{"url":"https://api.freeagent.com/v2/invoices/1","contact":"https://api.freeagent.com/v2/contacts/1"},{"url":"https://api.freeagent.com/v2/invoices/2","contact":"https://api.freeagent.com/v2/contacts/2"}]}

var info2 = {"invoices":[{"url":"https://api.freeagent.com/v2/invoices/3","contact":"https://api.freeagent.com/v2/contacts/3"},{"url":"https://api.freeagent.com/v2/invoices/4","contact":"https://api.freeagent.com/v2/contacts/4"}]}

期望的结果：

var info3 = {"invoices":[{"url":"https://api.freeagent.com/v2/invoices/1","contact":"https://api.freeagent.com/v2/contacts/1"},{"url":"https://api.freeagent.com/v2/invoices/2","contact":"https://api.freeagent.com/v2/contacts/2"},{"url":"https://api.freeagent.com/v2/invoices/3","contact":"https://api.freeagent.com/v2/contacts/3"},{"url":"https://api.freeagent.com/v2/invoices/4","contact":"https://api.freeagent.com/v2/contacts/4"}]}

有什么函数可以用来做这个吗？

Answer 1

最简单的方法是将它们反序列化为同一类的 2 个实例，将数组项添加在一起，然后将对象序列化回字符串。

Info info1 = // deserialize info1
Info info2 = // deserialize info2

info1.Invoices.AddRange(info2.Invoices);

string json = // serialize info1

类型：

class Info
{
    List<Invoice> Invoices;
}

class Invoice
{
    string URL;
    string Contact;
}
