JSON.Net：所有的私人领域的系列化力，并在子类中的所有领域 [英] JSON.Net: Force serialization of all private fields and all fields in sub-classes

问题描述

我有几个不同类的类和我向这些类的信息给客户端，但我不希望他们都发出这样的一些是私人的，一些有 [的JSONObject（ MemberSerialization.OptIn）] 标志等。

不过，现在我想要做的所有这些对象的备份，当我需要关闭服务器，并每隔12小时（我不希望使用数据库），所以我想这样做（如果可能）是强制JSON.Net序列化对象和属于该对象的所有对象转换。

例如：

 类Foo
{
 公众诠释数目;
 私人字符串名称;
 私人PrivateObject PO =新PrivateObject（）; 公共字符串的toJSON（）
 {/ *我的序列化公共领域，我的财产和对象PrivateObject * /}}
 

我想这code（即使它是过时的），但它不序列与我的目标对象：

  Newtonsoft.Json.JsonSerializerSettings JSS =新Newtonsoft.Json.JsonSerializerSettings（）;        Newtonsoft.Json.Serialization.DefaultContractResolver DCR =新Newtonsoft.Json.Serialization.DefaultContractResolver（）;
        dcr.DefaultMembersSearchFlags | = System.Reflection.BindingFlags.NonPublic;
        jss.ContractResolver = DCR;        返回Newtonsoft.Json.JsonConvert.SerializeObject（这一点，JSS）;
 

解决方案

这应该工作：

  VAR seetings =新JsonSerializerSettings（）{ContractResolver =新MyContractResolver（）};
VAR JSON = JsonConvert.SerializeObject（OBJ，设置）;

    保护覆盖的IList＆LT; JsonProperty＆GT; CreateProperties（类型类型，MemberSerialization memberSerialization）
    {
        VAR道具= type.GetProperties（BindingFlags.Public | BindingFlags.NonPublic可| BindingFlags.Instance）
                        。选择（p值=＆GT; base.CreateProperty（对，memberSerialization））
                    .Union（type.GetFields（BindingFlags.Public | BindingFlags.NonPublic可| BindingFlags.Instance）
                               。选择（F =＆GT; base.CreateProperty（F，memberSerialization）））
                    .ToList（）;
        props.ForEach（P =＆GT; {p.Writable = TRUE; p.Readable = TRUE;}）;
        返回道具;
    }
}
 

I have a class with several different classes and I send the information in these classes out to clients but I don't want to send them all out so some are private, some have the [JsonObject(MemberSerialization.OptIn)] flag etc.

However, now I want to do a backup of all these objects when I need to shutdown the server and every 12 hours (I don't want to use a database) so what I want to do (if possible) is to force the JSON.Net Serializer to convert the object and all the object belonging to that object.

For example:

class Foo
{
 public int Number;
 private string name;
 private PrivateObject po = new PrivateObject();

 public string ToJSON()
 { /* Serialize my public field, my property and the object PrivateObject */ }

}

I tried this code (even though it's obsolete) but it doesn't Serialize the objects related to my object:

 Newtonsoft.Json.JsonSerializerSettings jss = new Newtonsoft.Json.JsonSerializerSettings();

        Newtonsoft.Json.Serialization.DefaultContractResolver dcr = new Newtonsoft.Json.Serialization.DefaultContractResolver();
        dcr.DefaultMembersSearchFlags |= System.Reflection.BindingFlags.NonPublic;
        jss.ContractResolver = dcr;



        return Newtonsoft.Json.JsonConvert.SerializeObject(this, jss);

解决方案

This should work:

var seetings = new JsonSerializerSettings() { ContractResolver = new MyContractResolver() };
var json = JsonConvert.SerializeObject(obj, settings);

public class MyContractResolver : Newtonsoft.Json.Serialization.DefaultContractResolver
{
    protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
    {
        var props = type.GetProperties(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance)
                        .Select(p => base.CreateProperty(p, memberSerialization))
                    .Union(type.GetFields(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance)
                               .Select(f => base.CreateProperty(f, memberSerialization)))
                    .ToList();
        props.ForEach(p => { p.Writable = true; p.Readable = true; });
        return props;
    }
}
