使用Json.Net序列化哈希表 [英] Serialize hashtable using Json.Net

问题描述

我有一个哈希表，其键的类型为整数，但是当使用json.net反序列化时，键又以字符串形式返回，有没有办法使用json.net序列化/反序列化将键类型保留在哈希表上?该哈希表是"MyType"类型的属性

I have a hashtable whose keys are of type integer, however when deserializing using json.net the keys come back as strings, is there a way to keep the key type on hashtable using json.net serialization/deserialization? This hashtable is a property of the type 'MyType'

var settings = new JsonSerializerSettings();
settings.TypeNameHandling = TypeNameHandling.Objects;
string json = JsonConvert.SerializeObject(o, Formatting.Indented, settings);

 mo = JsonConvert.DeserializeObject<MyType>(json, new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.Objects });

public Hashtable jsonViews
{
    get { return mViews; }
    set { mViews = value; }
}

推荐答案

问题是System.Collections.Hashtable的类型不是很强-它可以容纳任何类型的对象，并且JSON.NET最有可能序列化字符串表示形式您的哈希表内容.

The problem is that the System.Collections.Hashtable isn't strongly typed - it will hold any type of object, and JSON.NET is most likely serialising the string representation of your hashtable contents.

在花太多时间按摩JSON.NET序列化器/反序列化器以弥补这一点之前，您可能需要考虑将Hashtable换成Dictionary<TKey, TValue>.就性能而言，它几乎是相同的，但是却为您提供了强类型集合的优势和安全性.

Before you spend too much time massaging the JSON.NET serializer/deserializer to compensate for this, you might want to consider switching your Hashtable out for a Dictionary<TKey, TValue>. It's almost identical in terms of performance, but gives you the advantage and safety of a strongly-typed collection.

强类型集合可以解决您的Json.NET反序列化问题，因为Json.NET可以从字典中推断类型.

A strongly-typed collection will resolve your Json.NET deserialization issues, as Json.NET can infer the type from the dictionary.

在Hashtable上使用Dictionary<TKey,TValue> 在这里讨论.
