I'm trying to use a settings file to store the user preferences when he/she logins on the application.

我正在尝试使用一个设置文件来存储用户登录应用程序时的首选项。

I defined them as user (scope) but I am getting

我将它们定义为user (scope)，但我正在获取

System.Configuration.ConfigurationErrorsException: The current configuration system does not support user-scoped settings.

System.Configuration。ConfigurationErrorsException:当前的配置系统不支持用户范围的设置。

User-scoped settings are indeed not supported for a Web application. And they wouldn't work, User settings would have to be saved under the Users\<username>\... folder on the server.

用户范围的设置实际上不支持Web应用程序。它们不能工作，用户设置必须保存在Users\ \…文件夹在服务器上。

You have a wide choice of web techniques:

When I had this problem, it turned out that I had a reference to a dll which had a Settings.settings (or Settings.Designer.cs) file.

当我遇到这个问题时，我发现我有一个对具有设置的dll的引用。设置(或Settings.Designer.cs)文件。

What happens is that when editing the Setting.settings file, upon clicking the blank line at the bottom, a new line is added with template information and a default user setting instead of application setting. This is a nice feature but you could see how after changing the template and adding your new setting, then clicking below to lose focus a new template line is added and if you are not paying attention, you accidently add a user setting. Check if you have this file in a referenced dll and remove any user settings.

当编辑设置时。设置文件，当单击底部的空行时，将添加一个新的行，其中包含模板信息和默认的用户设置，而不是应用程序设置。这是一个很好的特性，但是您可以看到，在更改模板并添加新设置之后，单击下面以失去焦点，将添加一个新的模板行，如果您不注意，您将意外地添加一个用户设置。检查这个文件是否在引用的dll中，并删除任何用户设置。

You can make Application scope settings writable by simply adding a setter to the property definition in Settings.Designer.cs. For instance:

您可以通过在Settings.Designer.cs. cs中向属性定义添加一个setter来使应用程序范围设置可写入。例如:

[global::System.Configuration.ApplicationScopedSettingAttribute()]
[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
[global::System.Configuration.DefaultSettingValueAttribute("AdminContext")]
public string DbContext
{
    get { return ((string)(this["DbContext"])); }
    set { this["DbContext"] = value; } }

The caveat is that the Settings.Designer.cs is auto-generated, and therefore if you use the designer UI, your setters will be overwritten.

需要注意的是，Settings.Designer。cs是自动生成的，因此如果您使用设计器UI，您的setter将被覆盖。

This works in console and web applications.

这适用于控制台和web应用程序。
