registry/configurationSettings/XML参数似乎仍然非常活跃。随着技术的进步，我都用过了，但我最喜欢的是基于Threed的系统和隔离存储的结合。

下面的示例允许将名为properties的对象存储到隔离存储中的文件中。如:

AppSettings.Save(myobject, "Prop1,Prop2", "myFile.jsn");

可以使用以下方法恢复属性:

AppSettings.Load(myobject, "myFile.jsn");

这只是一个示例，并不是最佳实践的建议。

internal static class AppSettings
{
    internal static void Save(object src, string targ, string fileName)
    {
        Dictionary<string, object> items = new Dictionary<string, object>();
        Type type = src.GetType();

        string[] paramList = targ.Split(new char[] { ',' });
        foreach (string paramName in paramList)
            items.Add(paramName, type.GetProperty(paramName.Trim()).GetValue(src, null));

        try
        {
            // GetUserStoreForApplication doesn't work - can't identify.
            // application unless published by ClickOnce or Silverlight
            IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForAssembly();
            using (IsolatedStorageFileStream stream = new IsolatedStorageFileStream(fileName, FileMode.Create, storage))
            using (StreamWriter writer = new StreamWriter(stream))
            {
                writer.Write((new JavaScriptSerializer()).Serialize(items));
            }

        }
        catch (Exception) { }   // If fails - just don't use preferences
    }

    internal static void Load(object tar, string fileName)
    {
        Dictionary<string, object> items = new Dictionary<string, object>();
        Type type = tar.GetType();

        try
        {
            // GetUserStoreForApplication doesn't work - can't identify
            // application unless published by ClickOnce or Silverlight
            IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForAssembly();
            using (IsolatedStorageFileStream stream = new IsolatedStorageFileStream(fileName, FileMode.Open, storage))
            using (StreamReader reader = new StreamReader(stream))
            {
                items = (new JavaScriptSerializer()).Deserialize<Dictionary<string, object>>(reader.ReadToEnd());
            }
        }
        catch (Exception) { return; }   // If fails - just don't use preferences.

        foreach (KeyValuePair<string, object> obj in items)
        {
            try
            {
                tar.GetType().GetProperty(obj.Key).SetValue(tar, obj.Value, null);
            }
            catch (Exception) { }
        }
    }
}

登记处是不允许的。您不确定使用您的应用程序的用户是否有足够的权限写入注册表。

您可以使用app.config文件保存应用程序级别的设置(对于使用您的应用程序的每个用户都是相同的)。

我将把特定于用户的设置存储在一个XML文件中，该文件将保存在隔离存储或SpecialFolder中。ApplicationData目录。

其次，从。net 2.0开始，可以将值存储回app.config文件。

据我所知，.NET确实支持使用内置的应用程序设置功能持久化设置:

The Application Settings feature of Windows Forms makes it easy to create, store, and maintain custom application and user preferences on the client computer. With Windows Forms application settings, you can store not only application data such as database connection strings, but also user-specific data, such as user application preferences. Using Visual Studio or custom managed code, you can create new settings, read them from and write them to disk, bind them to properties on your forms, and validate settings data prior to loading and saving. - http://msdn.microsoft.com/en-us/library/k4s6c3a0.aspx

如果你使用Visual Studio，那么很容易获得持久化设置。在解决方案资源管理器中右键单击项目并选择属性。选择“设置”选项卡，如果“设置”不存在，则单击超链接。

使用Settings选项卡创建应用程序设置。Visual Studio创建文件设置。settings和settings . designer .settings包含从ApplicationSettingsBase继承的单例类settings。你可以从你的代码中访问这个类来读取/写入应用程序设置:

Properties.Settings.Default["SomeProperty"] = "Some Value";
Properties.Settings.Default.Save(); // Saves settings in application configuration file

此技术适用于控制台、Windows窗体和其他项目类型。

注意，您需要设置设置的scope属性。如果你选择了应用范围，那么Settings.Default。<你的属性>将是只读的。

参考:如何:在运行时使用c# - Microsoft Docs编写用户设置

ApplicationSettings类不支持将设置保存到app.config文件中。这在很大程度上是故意的;使用安全用户帐户运行的应用程序(如Vista UAC)没有对程序安装文件夹的写访问权。

您可以使用ConfigurationManager类来对抗系统。但简单的解决方法是进入设置设计器并将设置的范围更改为User。如果这造成了困难(例如，设置与每个用户相关)，则应该将Options特性放在单独的程序中，以便可以请求特权提升提示。或者放弃使用设置。
