c# - 如何将对象数组序列化为 JSON 字典？

Question

我需要将一组对象序列化为 JSON 字典。

像这样的数组项：

class Entry {
    public string Id{get;set;}
    public string Value{get;set;}
}

所以像数组一样

var arr = new[]
    {
        new Entry{Id = "one", Value = "First"},
        new Entry{Id = "two", Value = "Second"},
        new Entry{Id = "tri", Value = "Third"},
    };

我希望被序列化如下：

{
    one: {Title: "First"},
    two: {Title: "Second"},
    tri: {Title: "Third"}
}

可能吗？ContractResolver附近的东西？

谢谢。

Answer 1

使用Json.Net

string json = JsonConvert.SerializeObject(
                       arr.ToDictionary(x => x.Id, x => new { Title = x.Value }));

或 JavaScriptSerializer

string json2 = new JavaScriptSerializer()
             .Serialize(arr.ToDictionary(x => x.Id, x => new { Title = x.Value }));

Answer 2

使用JavaScriptSerializer：

var keyValues = new Dictionary<string, string>
           {
               { "one", "First" },
               { "two", "Second" },
               { "three", "Third" }
           };

JavaScriptSerializer js = new JavaScriptSerializer();
string json = js.Serialize(keyValues);
