Question

我在使用JSON作为配置时遇到了一些问题（目前无法让我的用户使用此程序使用Config.config或Program.exe.config，并且JSON更容易请阅读我的意见。所以这是代码：

    public static Bot bot = JsonConvert.DeserializeObject<Bot>(File.ReadAllText("Bot.config"));
    public static string nick = bot.configuration.BotName;

返回

string nick，这是我运行程序时遇到的错误：

未处理的异常：System.TypeInitializationException：类型初始值设定项 r'Bot.Program'抛出异常。 ---＆GT; System.NullReferenceException：Objec t引用未设置为对象的实例。在Program.cs中的Bot.Program..cctor（）：第38行 ---内部异常堆栈跟踪结束--- 在Bot.Program.Main（String [] args）

这就是我一直遇到的问题。

类：

 public class Bot
    {
        public Configuration configuration { get; set; }
        public Welcomesystem welcomeSystem { get; set; }
        public Twittersystem twitterSystem { get; set; }
        public Youtubesystem youtubeSystem { get; set; }
        public Weathersystem weatherSystem { get; set; }
        public Loyaltysystem loyaltySystem { get; set; }
        public Urldetection urlDetection { get; set; }
        public Commands commands { get; set; }
    }
    public class Configuration
    {
        public string BotName { get; set; }
        public string Channel { get; set; }
        public string Server { get; set; }
        public string OAuth { get; set; }
        public string BotAdmin { get; set; }
        public string _comment1 { get; set; }
    }
    public class Welcomesystem
    {
        public bool enabled { get; set; }
        public bool forSubsOnly { get; set; }
        public bool forRegOnly { get; set; }
        public string DefaultWelcome { get; set; }
    }
    public class Twittersystem
    {
        public bool enabled { get; set; }
        public string _comment2 { get; set; }
        public string APIKey { get; set; }
        public string APISecret { get; set; }
        public string TokenKey { get; set; }
        public string TokenSecret { get; set; }
    }
    public class Youtubesystem
    {
        public bool enabled { get; set; }
    }
    public class Weathersystem
    {
        public bool enabled { get; set; }
        public string authKey { get; set; }
        public string _comment3 { get; set; }
    }
    public class Loyaltysystem
    {
        public bool enabled { get; set; }
        public string _comment4 { get; set; }
    }
    public class Urldetection
    {
        public bool enabled { get; set; }
        public string defaultTimeout { get; set; }
        public string _comment5 { get; set; }
    }
    public class Commands
    {
        public bool Diablo_Command { get; set; }
        public bool Warcraft_Command { get; set; }
    }

我暂时不再使用SQLite数据绑定和Visual Studio 2013中的.settings文件。

当我遇到这个问题时，我使用的其他解决方案现在已被弃用，但我现在将此代码保留给需要它的任何人。

    public string Server = ConfigurationSettings.AppSettings["Server"].ToString();
    public string Port = ConfigurationSettings.AppSettings["Port"].ToString();
    public string Channel = ConfigurationSettings.AppSettings["Channel"].ToString();
    public string OAuth = ConfigurationSettings.AppSettings["OAuth"].ToString();
    public string Interval = ConfigurationSettings.AppSettings["Interval"].ToString();
    public string Currency = ConfigurationSettings.AppSettings["Currency"].ToString();
    public string Nick = ConfigurationSettings.AppSettings["Nick"].ToString();
    public string BaseAdmin = ConfigurationSettings.AppSettings["BaseAdmin"].ToString();

使用JSON作为配置会带来一些问题，其中之一就是它在启动时会滞后我的应用程序，编写它也会很困难。所以，如果您在这里，我建议您使用XML作为配置或.Settings，因为它们比使用JSON更可行，更快。

将JSON作为配置读取，返回值null并崩溃
