如何在程序的设置中存储一个双精度数组，然后再检索它？

代码

string[,] user_credits = new string[user_credits_array, 10];
                    user_credits[new_user_id, 0] = user_name;
                    user_credits[new_user_id, 1] = user_email;
                    user_credits[new_user_id, 2] = user_acc_name;
                    user_credits[new_user_id, 3] = user_acc_pass;
                    user_credits[new_user_id, 4] = sSelectedClient;
                    user_credits[new_user_id, 5] = server_inkomend;
                    user_credits[new_user_id, 6] = server_uitgaand;
                    user_credits[new_user_id, 7] = server_port + "";
                    user_credits[new_user_id, 8] = ssl_state;

如您所见，我是否使用用户的 id 将信息存储在一起。我以这种方式存储它：

Properties.Settings.Default.user_credits = user_credits;
Properties.Settings.Default.Save();

我做对了吗？现在数组还在用户设置中吗？

我怎样才能摆脱它（具有正确用户 ID 的设置）？

我知道这听起来可能很疯狂，但我认为这是最好的方法。但如果你们知道更好的方法，请告诉我。我

编辑1：

我有这段代码：

string[,] user_credits = new string[user_credits_array, 10];
user_credits[new_user_id, 0] = user_name;
user_credits[new_user_id, 1] = user_email;
user_credits[new_user_id, 2] = user_acc_name;
user_credits[new_user_id, 3] = user_acc_pass;
user_credits[new_user_id, 4] = sSelectedClient;
user_credits[new_user_id, 5] = server_inkomend;
user_credits[new_user_id, 6] = server_uitgaand;
user_credits[new_user_id, 7] = server_port + "";
user_credits[new_user_id, 8] = ssl_state;

MySettings settingsTest = new MySettings();
settingsTest.Save(MySettings.GetDefaultPath());
MySettings anotherTest = MySettings.Load(MySettings.GetDefaultPath());

运行代码后，XML 文件如下所示：

<Complex name="Root" type="WeProgram_Mail.MySettings, WeProgram_Mail, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
  <Properties>
    <Null name="user_credits" />
  </Properties>

现在我不明白为什么没有保存数组。因为我有这条线

public string[,] user_credits { get; set; }

而且我认为这会从数组中获取用户设置，但不知何故他们没有。

用于System.Collections.Specialized.StringCollection为每个字符串设置和添加一个 XML 字符串（包含您的附加属性，如 'user_name' 或 'user_email'）：

var collection = new StringCollection {"<user_name>aaaa<user_name><user_email>asdfasd@asdfasd</user_email>"};
Properties.Settings.Default.MySetting = collection;
Properties.Settings.Default.Save();

并在需要属性时解析 XML。

好吧，通常我只使用http://www.sharpserializer.com/en/index.html

它使用起来非常简单，速度很快，并且可以或多或少地序列化任何东西，包括字典等。很好的是，您可以序列化为多种目标格式，如二进制。

编辑：使用 SharpSerializer 进行序列化的示例。没有编译代码，但应该没问题。缺点：要存储的属性必须是公共的...

        public string[,] user_credits { get; set; }

啊，我看到了问题。正如您在 XML 文件中看到的，MySettings 实例（settingsTest）中的数组为空。那是因为您在 settingsTest 对象之外填充了数组，并且从不接触或初始化 settingsTest.user_credits...

尝试以下操作：

MySettings settingsTest = new MySettings();
settingsTest.user_credits = new string[user_credits_array, 10];
settingsTest.user_credits[new_user_id, 0] = user_name;
settingsTest.user_credits[new_user_id, 1] = user_email;
settingsTest.user_credits[new_user_id, 2] = user_acc_name;
settingsTest.user_credits[new_user_id, 3] = user_acc_pass;
settingsTest.user_credits[new_user_id, 4] = sSelectedClient;
settingsTest.user_credits[new_user_id, 5] = server_inkomend;
settingsTest.user_credits[new_user_id, 6] = server_uitgaand;
settingsTest.user_credits[new_user_id, 7] = server_port + "";
settingsTest.user_credits[new_user_id, 8] = ssl_state;


settingsTest.Save(MySettings.GetDefaultPath());
MySettings anotherTest = MySettings.Load(MySettings.GetDefaultPath());

啊，我们在 2012 年还很年轻……而不是使用 JSON 序列化程序来保存您的项目列表（或数组）。我的示例使用了一个名为MRU而不是 doubles 的类，但想法是一样的：

进入设置

 // Extract from ObservableCollection<MRU>.
 List<MRU> asList = MRUS.ToList<MRU>();
 Properties.Settings.Default.MRUS = JsonSerializer.Serialize(asList);
 Properties.Settings.Default.Save();

超出设置

var mruText = Properties.Settings.Default.MRUS;
return string.IsNullOrWhiteSpace(mruText) ? new List<MRU>()
    : JsonSerializer.Deserialize<List<MRU>>(mruText);
