JSON.NET（WebApi2） - 序列化属性，但反序列化过程跳过 [英] JSON.NET (WebApi2) - Serialize property, but skip during deserialization

问题描述

我知道 [JsonIgnore] 这完全忽略了性，我知道 ShouldSerializePropertyName 的赋予有条件的序列化，但我找不到任何标记属性被序列化为JSON正常，但反序列化过程中未设置。

I know of [JsonIgnore] which ignores properties altogether, I know of ShouldSerializePropertyName which gives conditional serialization, but I cannot find anything to mark property to be serialized into JSON normally, but not set during deserialization.

我可以写一个解决方法：

I could write a workaround:

[JsonIgnore]
public string MyValue{get;set;}

public string MyValueForJson {get{return MyValue;}

但它是一个不得已而为之。是否有某种方式 - 不是自定义转换器等其他 - 我不希望这一领域的反序列化过程中被填充到EX preSS

but it is a last resort. Is there some way - other than custom converters etc. - to express that I don't want that field to be populated during deserialization?

推荐答案

据我了解，你想用JSON字符串的所有属性序列化对象，但只提取选定的性能，同时反序列化该字符串。

As I understand you want to serialize object with all properties in json string but retrieve only selected properties while deserialization on that string.

如果这是这样，那么，我就在那里我创建了基本类型和DerivedType类的话，我序列化派生类型为JSON字符串反序列化的同时，我希望它在基本类型实例类似的规定。所以写了这个code：

If this is case then, I had a similar requirement where I created BaseType and DerivedType classes then I serialize derived type into Json string while deserialization I want it in Base type instance. So wrote this code :

    using System.Web.Script.Serialization;

    public static TB CastToBase<T, TB>(this T derivedTypeInstance) 
        {
            var serializer = new JavaScriptSerializer();
            var baseTypeInstance = serializer.Deserialize<TB>(serializer.Serialize(derivedTypeInstance));
            return baseTypeInstance;
        }
