使用Json.net和c#反序列化嵌套的json字符串

Question

我的字符串json

{"data":[{"id":"CAMVqgY1g1cdLU5anDL69Tt5pyRh51-qkyKMHWHgH2mAG+vn+xQ%40mail.gmail.com","content":"Coba ngirim email mohon diterimarn","judul":"coba 1","sender":""Aldo Erianda""},{"id":"CAMVqgY1Trb5ZShRxzoX%3D0xaVQs5-Psh0J8V3JwQYVevcr8i5WA%40mail.gmail.com","content":"sampai nga yarn","judul":"coba 2","sender":""Aldo Erianda""}]}

我想计数记录内"数据"，并显示在控制台或richtextbox的记录。几个教程仍然让我难以理解。我该怎么一步步做呢?

Answer 1

这应该适用于您的具体情况。它不能推广到任何json字符串。

var json = "{"data":[{"id":"CAMVqgY1g1cdLU5anDL69Tt5pyRh51-qkyKMHWHgH2mAG+vn+xQ%40mail.gmail.com","content":"Coba ngirim email mohon diterimarn","judul":"coba 1","sender":"Aldo Erianda"},{"id":"CAMVqgY1Trb5ZShRxzoX%3D0xaVQs5-Psh0J8V3JwQYVevcr8i5WA%40mail.gmail.com","content":"sampai nga yarn","judul":"coba 2","sender":"Aldo Erianda"}]}";
var deserialized = JsonConvert.DeserializeObject<IDictionary<string, JArray>>(json);
JArray recordList = deserialized["data"];
foreach (JObject record in recordList)
{
    Console.WriteLine("id: " + record["id"]);
    Console.WriteLine("content: " + record["content"]);
    Console.WriteLine("judul: " + record["judul"]);
    Console.WriteLine("sender: " + record["sender"]);
}
Console.WriteLine("count: " + recordList.Count);

注意:我稍微修改了你的json通过转义所有的引号使其成为一个有效的c#字符串。此外，我认为你在发件人的价值周围有额外的报价。
