第一个回答：

Try this

AppDomain.CurrentDomain.SetupInformation.ConfigurationFile

Hope it helps

第二个回答:

Strictly speaking, there is no single configuration file. Excluding ASP.NET¹ there can be three configuration files using the inbuilt (System.Configuration) support. In addition to the machine config: app.exe.config, user roaming, and user local.

To get the "global" configuration (exe.config):

ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
                    .FilePath

Use different ConfigurationUserLevel values for per-use roaming and non-roaming configuration files.

Examples

                Console.WriteLine($"AppDomain.CurrentDomain.SetupInformation.ConfigurationFile = {AppDomain.CurrentDomain.SetupInformation.ConfigurationFile}");
                Console.WriteLine();

                var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
                Console.WriteLine($"ConfigurationUserLevel.None = {configFile.FilePath}");
                Console.WriteLine();
                configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoaming);
                Console.WriteLine($"ConfigurationUserLevel.PerUserRoaming = {configFile.FilePath}");
                Console.WriteLine();

                configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal);
                Console.WriteLine($"ConfigurationUserLevel.PerUserRoamingAndLocal = {configFile.FilePath}");
                Console.WriteLine();

exe文件所处路径  d/SourceCode/CSharp/ConsoleTest/ConsoleApplication1/bin/Debug

输出结果如下：

AppDomain.CurrentDomain.SetupInformation.ConfigurationFile = D:SourceCodeCSharpConsoleTestConsoleApplication1inDebugConsoleApp.exe.Config

ConfigurationUserLevel.None =                                                  D:SourceCodeCSharpConsoleTestConsoleApplication1inDebugConsoleApp.exe.Config

ConfigurationUserLevel.PerUserRoaming = C:UsersAdministratorAppDataRoamingChuckLuConsoleApp.exe_Url_3lsb0kxaaocmfdaqj3ouxzvvp3phypxi1.0.0.0user.config

ConfigurationUserLevel.PerUserRoamingAndLocal = C:UsersAdministratorAppDataLocalChuckLuConsoleApp.exe_Url_3lsb0kxaaocmfdaqj3ouxzvvp3phypxi1.0.0.0user.config

AppDomain.CurrentDomain.SetupInformation.ConfigurationFile和ConfigurationUserLevel.None  的路径是一致的

ConfigurationManager.OpenMappedExeConfiguration Method
