如何在 servicestack json 序列化程序中省略仅获取属性? [英] How to omit Get only properties in servicestack json serializer?

问题描述

我有一个对象，我正在使用 ServiceStack.Text 命名空间中的 ToJson<>() 方法对其进行反序列化.

I have an object which I am de-serializing using ToJson<>() method from ServiceStack.Text namespace.

如何在序列化过程中省略所有 GET 属性?有没有像 [Ignore] 这样的属性或者我可以用来装饰我的属性的东西，这样它们就可以被省略?

How to omit all the GET only propeties during serialization? Is there any attribute like [Ignore] or something that I can decorate my properties with, so that they can be omitted?

谢谢

推荐答案

ServiceStack 的文本序列化器如下.NET 的 DataContract 序列化程序行为，这意味着您可以通过使用选择退出 [IgnoreDataMember] 属性

ServiceStack's Text serializers follows .NET's DataContract serializer behavior, which means you can ignore data members by using the opt-out [IgnoreDataMember] attribute

public class Poco 
{
    public int Id { get; set; }

    public string Name { get; set; }

    [IgnoreDataMember]
    public string IsIgnored { get; set; }
}

一个选择加入的替代方法是用[DataMember] 装饰您想要序列化的每个属性.其余属性未序列化，例如:

An opt-in alternative is to decorate every property you want serialized with [DataMember]. The remaining properties aren't serialized, e.g:

[DataContract]
public class Poco 
{
    [DataMember]
    public int Id { get; set; }

    [DataMember]
    public string Name { get; set; }

    public string IsIgnored { get; set; }
}

最后还有一个不需要属性的非侵入式选项，例如:

Finally there's also a non-intrusive option that doesn't require attributes, e.g:

JsConfig<Poco>.ExcludePropertyNames = new [] { "IsIgnored" };

动态指定应该序列化的属性

ServiceStack 的 Serializers 还支持动态控制序列化，通过提供传统命名的 ShouldSerialize({PropertyName}) 方法来指示属性是否应该被序列化，例如:

Dynamically specifying properties that should be serialized

ServiceStack's Serializers also supports dynamically controlling serialization by providing conventionally named ShouldSerialize({PropertyName}) methods to indicate whether a property should be serialized or not, e.g:

public class Poco 
{
    public int Id { get; set; }

    public string Name { get; set; }

    public string IsIgnored { get; set; }

    public bool? ShouldSerialize(string fieldName)
    {
        return fieldName == "IsIgnored";
    }
}
