Question

我正在尝试将字典序列化为json，但它对我不起作用。

这是我的字典：

public Dictionary<string, Dictionary<string, string>> roaming = new Dictionary<string,Dictionary<string, string>>();

这就是我试图序列化它的方式：

string json = JsonConvert.SerializeObject(this.client); // the dictionary is inside client object
//write string to file
System.IO.File.WriteAllText(@"path", json);

我做错了吗？（对于int或string类型的成员，它工作正常）。

对我来说工作正常，可能是库版本或其中包含的数据的问题。这是我能够工作的原因：

简单的“客户”类（只是根据嵌套字典集进行一些简单的翻译）：

public class Client
{
    public Dictionary<string, Dictionary<string, string>> roaming
    {
        get { return this._roaming ?? (this._roaming = new Dictionary<string, Dictionary<string, string>>()); }
        set { this._roaming = value; }
    }
    private Dictionary<string, Dictionary<string, string>> _roaming;


    public Client()
    {
        this.roaming.Add("en", new Dictionary<string, string> {
            { "login", "login" },
            { "logout", "logout" },
            { "submit", "submit" }
        });
        this.roaming.Add("sp", new Dictionary<string, string> {
            { "login", "entrar" },
            { "logout", "salir" },
            { "submit", "presentar" }
        });
    }
}

然后，实例化并序列化：

Client client = new Client();
String json = JsonConvert.SerializeObject(client, Newtonsoft.Json.Formatting.Indented);

[预期]结果：

{
  "roaming": {
    "en": {
      "login": "login",
      "logout": "logout",
      "submit": "submit"
    },
    "sp": {
      "login": "entrar",
      "logout": "salir",
      "submit": "presentar"
    }
  }
}

将字典序列化为json文件
