問(wèn)題描述

我有一個(gè)包含幾個(gè)不同類的類，我將這些類中的信息發(fā)送給客戶，但我不想將它們?nèi)堪l(fā)送出去，所以有些是私有的，有些有 [JsonObject(MemberSerialization.OptIn)] 標(biāo)志等

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.

但是，現(xiàn)在我想在需要關(guān)閉服務(wù)器時(shí)以及每 12 小時(shí)(我不想使用數(shù)據(jù)庫(kù))備份所有這些對(duì)象，所以我想做的(如果可能的話)是強(qiáng)制 JSON.Net Serializer 轉(zhuǎn)換對(duì)象和屬于該對(duì)象的所有對(duì)象.

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.

例如:

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 */ }
}

我嘗試了這段代碼(即使它已經(jīng)過(guò)時(shí))，但它沒(méi)有序列化與我的對(duì)象相關(guān)的對(duì)象:

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);

推薦答案

這應(yīng)該可行:

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

<小時(shí)>

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;
    }
}
