It depends on whether the setting you have chosen is at "User" scope or "Application" scope.

这取决于您选择的设置是在“用户”范围还是“应用程序”范围。

User scope

用户范围

User scope settings are stored in

用户范围设置存储在

C:\Documents and Settings\ username \Local Settings\Application Data\ ApplicationName

You can read/write them at runtime.

您可以在运行时读取/写入它们。

For Vista and Windows 7, folder is

对于 Vista 和 Windows 7，文件夹是

C:\Users\ username \AppData\Local\ ApplicationName

or

或者

C:\Users\ username \AppData\Roaming\ ApplicationName

Application scope

适用范围

Application scope settings are saved in AppName.exe.configand they are readonly at runtime.

应用程序范围设置保存在其中，AppName.exe.config并且它们在运行时是只读的。

All your settings are stored in the respective .config file.

您的所有设置都存储在相应的 .config 文件中。

The .settings file simply provides a strongly typed class for a set of settings that belong together, but the actual settings are stored in app.config or a .config file in your application.

.settings 文件只是为属于一起的一组设置提供强类型类，但实际设置存储在 app.config 或应用程序中的 .config 文件中。

If you add a .settings file, an app.config will be automatically added to house the settings if you don't already have one.

如果你添加了一个 .settings 文件，如果你还没有一个 app.config 文件，将会自动添加一个 app.config 来容纳这些设置。

It is in a folder with your application's name in Application Data folder in User's home folder (C:\documents and settings\user on xp and c:\users\user on Windows Vista).

它位于用户主文件夹（xp 上的 C:\documents and settings\user 和 Windows Vista 上的 c:\users\user）中的 Application Data 文件夹中具有您的应用程序名称的文件夹中。

There is some information herealso.

这里也有一些信息。

PS:- try accessing it by %appdata% in run box!

PS：- 尝试在运行框中通过 %appdata% 访问它！

If your settings file is in a web app, they will be in teh web.config file (right below your project. If they are in any other type of project, they will be in the app.config file (also below your project).

如果您的设置文件在 Web 应用程序中，它们将在 web.config 文件中（在您的项目正下方。如果它们在任何其他类型的项目中，它们将在 app.config 文件中（也在您的项目下方） .

As is pointed out in the comments: your design time application settings are in an app.config file for applications other than web applications. When you build, the app.config file is copied to the output directory, and will be named yourexename.exe.config. At runtime, only the file named yourexename.exe.config will be read.

正如评论中指出的那样：您的设计时应用程序设置位于 app.config 文件中，用于除 Web 应用程序之外的应用程序。构建时，app.config 文件被复制到输出目录，并将命名为yourexename.exe.config。在运行时，只会读取名为 yourexename.exe.config 的文件。

Two files: 1) An app.config or web.config file. The settings her can be customized after build with a text editer. 2) The settings.designer.cs file. This file has autogenerated code to load the setting from the config file, but a default value is also present in case the config file does not have the particular setting.

两个文件：1) app.config 或 web.config 文件。她的设置可以在使用文本编辑器构建后进行自定义。2) settings.designer.cs 文件。该文件具有自动生成的代码，用于从配置文件加载设置，但如果配置文件没有特定设置，也会存在默认值。

Here is the snippet you can use to programmatically get user.config file location:

以下是可用于以编程方式获取 user.config 文件位置的代码段：

public static string GetDefaultExeConfigPath(ConfigurationUserLevel userLevel)
{
  try
  {
    var UserConfig = ConfigurationManager.OpenExeConfiguration(userLevel);
    return UserConfig.FilePath;
  }
  catch (ConfigurationException e)
  {
    return e.Filename;
  }
}

ApplicationSettings (i.e. settings.settings) use PerUserRoamingAndLocal for user settings by default (as I remembered).

ApplicationSettings（即settings.settings）默认使用PerUserRoamingAndLocal 进行用户设置（我记得）。

Update:Strange but there are too many incorrect answers here. If you are looking for you user scoped settings file (user.config) it will be located in the following folder (for Windows XP):

更新：奇怪，但这里有太多不正确的答案。如果您正在寻找用户范围设置文件 (user.config)，它将位于以下文件夹中（对于 Windows XP）：

C:\Documents and Settings\(username)\Local Settings\Application Data\(company-name-if-exists)\(app-name).exe_(Url|StrongName)_(hash)\(app-version)\

C:\Documents and Settings\(username)\Local Settings\Application Data\(company-name-if-exists)\(app-name).exe_(Url|StrongName)_(hash)\(app-version)\

Url or StrongName depends on have you application assembly strong name or not.

Url 或 StrongName 取决于您是否具有应用程序程序集强名称。

Assuming that you're talking about desktop and not web applications:

假设您在谈论桌面而不是 Web 应用程序：

When you add settings to a project, VS creates a file named app.configin your project directory and stores the settings in that file. It also builds the Settings.csfile that provides the static accessors to the individual settings.

当您向项目添加设置时，VS 会app.config在您的项目目录中创建一个名为的文件，并将设置存储在该文件中。它还构建了Settings.cs为各个设置提供静态访问器的文件。

At compile time, VS will (by default; you can change this) copy the app.configto the build directory, changing its name to match the executable (e.g. if your executable is named foo.exe, the file will be named foo.exe.config), which is the name the .NET configuration manager looks for when it retrieves settings at runtime.

在编译时，VS 将（默认情况下；您可以更改此）将 复制app.config到构建目录，更改其名称以匹配可执行文件（例如，如果您的可执行文件名为foo.exe，则文件将被命名为foo.exe.config），即 . NET 配置管理器在运行时检索设置时查找。

If you change a setting through the VS settings editor, it will update both app.configand Settings.cs. (If you look at the property accessors in the generated code in Settings.cs, you'll see that they're marked with an attribute containing the default value of the setting that's in your app.configfile.) If you change a setting by editing the app.configfile directly, Settings.cswon't be updated, but the new value will still be used by your program when you run it, because app.configgets copied to foo.exe.configat compile time. If you turn this off (by setting the file's properties), you can change a setting by directly editing the foo.exe.configfile in the build directory.

如果您通过 VS 设置编辑器更改设置，它将同时更新app.config和Settings.cs. （如果您查看 中生成的代码中的属性访问器Settings.cs，您会看到它们标有一个属性，该属性包含app.config文件中设置的默认值。）如果您通过app.config直接编辑文件来更改设置，Settings.cs不会更新，但新值在您运行时仍会被您的程序使用，因为在编译时app.config会被复制到foo.exe.config。如果您将其关闭（通过设置文件的属性），您可以通过直接编辑foo.exe.config构建目录中的文件来更改设置。

Then there are user-scoped settings.

然后是用户范围的设置。

Application-scope settings are read-only. Your program can modify and save user-scope settings, thus allowing each user to have his/her own settings. These settings aren't stored in the foo.exe.configfile (since under Vista, at least, programs can't write to any subdirectory of Program Fileswithout elevation); they're stored in a configuration file in the user's application data directory.

应用程序范围设置是只读的。您的程序可以修改和保存用户范围设置，从而允许每个用户拥有他/她自己的设置。这些设置没有存储在foo.exe.config文件中（至少在Vista下，程序不能写入任何Program Files没有提升的子目录）；它们存储在用户应用程序数据目录中的配置文件中。

The path to that file is %appdata%\%publisher_name%\%program_name%\%version%\user.config, e.g. C:\Users\My Name\AppData\Local\My_Company\My_Program.exe\1.0.0\user.config. Note that if you've given your program a strong name, the strong name will be appended to the program name in this path.

该文件的路径是%appdata%\%publisher_name%\%program_name%\%version%\user.config，例如C:\Users\My Name\AppData\Local\My_Company\My_Program.exe\1.0.0\user.config。请注意，如果您为程序指定了强名称，则该强名称将附加到此路径中的程序名称之后。

I know it's already answered but couldn't you just synchronize the settings in the settings designer to move back to your default settings?

我知道它已经回答了，但是您不能只同步设置设计器中的设置以返回默认设置吗？

回答by Kildareflare

Erm, can you not just use Settings.Default.Reset() to restore your default settings?

嗯，你不能只使用 Settings.Default.Reset() 来恢复你的默认设置吗？

While browsing around to figure out about the hash in the folder name, I came across (via this answer):

The exact path of the user.configfiles looks something like this:

<Profile Directory>\<Company Name>\<App Name>_<Evidence Type>_<Evidence Hash>\<Version>\user.config

where

<Profile Directory>- is either the roaming profile directory or the local one. Settings are stored by default in the local user.configfile. To store a setting in the roaming user.configfile, you need to mark the setting with the SettingsManageabilityAttributewith SettingsManageabilityset to Roaming.

<Company Name>- is typically the string specified by the AssemblyCompanyAttribute(with the caveat that the string is escaped and truncated as necessary, and if not specified on the assembly, we have a fallback procedure).

<App Name>- is typically the string specified by the AssemblyProductAttribute(same caveats as for company name).

<Evidence Type>and <Evidence Hash>- information derived from the app domain evidence to provide proper app domain and assembly isolation.

<Version>- typically the version specified in the AssemblyVersionAttribute. This is required to isolate different versions of the app deployed side by side.

The file name is always simply 'user.config'.

user.config文件的确切路径如下所示：

<Profile Directory>\<Company Name>\<App Name>_<Evidence Type>_<Evidence Hash>\<Version>\user.config

在哪里

<Profile Directory>- 是漫游配置文件目录或本地目录。默认情况下，设置存储在本地user.config文件中。要将设置存储在漫游user.config文件中，您需要将设置标记为SettingsManageabilityAttributewithSettingsManageability设置为Roaming。

<Company Name>- 通常是由 the 指定的字符串AssemblyCompanyAttribute（需要注意的是，该字符串会根据需要进行转义和截断，如果未在程序集中指定，我们有一个回退过程）。

<App Name>- 通常是由AssemblyProductAttribute（与公司名称相同的警告）指定的字符串。

<Evidence Type>和<Evidence Hash>-从所述应用程序域的证据中得到的信息，以提供适当的应用程序域和组件隔离。

<Version>- 通常是AssemblyVersionAttribute. 这是隔离并排部署的应用程序的不同版本所必需的。

文件名总是简单的“ user.config”。
