如何做一个元组序列，并从JSON反序列化？ [英] How does a Tuple serialize to and deserialize from JSON?

问题描述

我很好奇如何使用元组LT; T1，T2，T3，...> 序列化和反序列化。我搜索使用关键字JSON和元组，但我找不到我想要的东西。

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.

推荐答案

我测试通过的UnitTest 和 Json.net 和测试代码是如下。结果表明元组LT; T1，T2，T3，...> 是序列化和deserializable。因此，我可以在我的应用程序中使用它们。

I test by UnitTest and 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.

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

的

Tuple.Create（自己，嘻嘻，真）将序列化到字符串{项目1：一，项目2 嘻嘻，项目3：真正}，它可以反序列化回元组LT;字符串，字符串，布尔> 键入

Comments

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.
