How does a Tuple serialize to and deserialize from JSON?
提问by AechoLiu
I am curious about how the Tuple<T1, T2, T3, ...>serializes and deserializes. I searched using keywords "json" and "tuple" but I could not find what I want.
我很好奇Tuple<T1, T2, T3, ...>序列化和反序列化的方式。我使用关键字“json”和“tuple”进行搜索，但找不到我想要的。

I test by UnitTestand Json.net, and the test codes is as following. The results shows Tuple<T1,T2,T3,...>is serializable and deserializable. So I can use them in my application.
我通过UnitTest和Json.net测试，测试代码如下。结果显示Tuple<T1,T2,T3,...>可序列化和反序列化。所以我可以在我的应用程序中使用它们。
Test codes
测试代码
public class Foo {
public List<Tuple<string, string, bool>> Items { get; set; }
public Foo()
{
Items = new List<Tuple<string, string, bool>>();
}
public override string ToString()
{
StringBuilder sb = new StringBuilder();
foreach (var a in Items)
{
sb.Append(a.Item1 + ", " + a.Item2 + ", " + a.Item3.ToString() + "\r\n");
}
return sb.ToString();
}
}
[TestClass]
public class NormalTests
{
[TestMethod]
public void TupleSerialization()
{
Foo tests = new Foo();
tests.Items.Add(Tuple.Create("one", "hehe", true));
tests.Items.Add(Tuple.Create("two", "hoho", false));
tests.Items.Add(Tuple.Create("three", "ohoh", true));
string json = JsonConvert.SerializeObject(tests);
Console.WriteLine(json);
var obj = JsonConvert.DeserializeObject<Foo>(json);
string objStr = obj.ToString();
Console.WriteLine(objStr);
}
}

注释
The Tuple.Create("own","hehe",true)will be serialize to string {"Item1":"one","Item2":"hehe","Item3":true}, and it can be deserialized back to Tuple<string,string,bool>type.
在Tuple.Create("own","hehe",true)将序列化到字符串{“项目1”：“一”，“项目2”：“嘻嘻”，“项目3”：真正}，并且它可以被反序列化回Tuple<string,string,bool>类型。

If you are looking for a short answer. I am using JsonConvert.
如果您正在寻找简短的答案。我正在使用JsonConvert。
var testTuple = Tuple.Create(1234, "foo", true);
var serialized = JsonConvert.SerializeObject(testTuple);
Console.WriteLine(serialized);
// prints: {"Item1":1234,"Item2":"foo","Item3":true}
I made a minimal fiddle.

Thank you Hinrich to the dotnetfiddle link above.
感谢 Hinrich 到上面的 dotnetfiddle 链接。
i used the same link, and got to know how Conversion works between Json objects and Tuples. Below is the code :
我使用了相同的链接，并了解了 Json 对象和元组之间的转换是如何工作的。下面是代码：
using System;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
public class Program
{
public static void Main()
{
var testTuple = Tuple.Create<int, string, bool>(1234, "foo", true);
var serialized = JsonConvert.SerializeObject(testTuple);
Console.WriteLine(serialized);
JObject test = ((JObject)JsonConvert.DeserializeObject(serialized));
string strSerialized = JsonConvert.SerializeObject(test);
//Tuple<int, string, bool> testTuple1 = JsonConvert.DeserializeObject<Tuple<int, string, bool>>(serialized); // WORKs
Tuple<int, string, bool> testTuple1 = JsonConvert.DeserializeObject<Tuple<int, string, bool>>(strSerialized); // WORKs
Console.WriteLine(testTuple1.Item1.ToString());
}
}
Hope someone finds this helpful.
