So there are really two ways to go about this. Option 1 : Options Class You have an appsettings.json file : { “myConfiguration”: { “myProperty”: true } } You create a Configuration POCO like so : public class MyConfiguration { public bool MyProperty { get; set; } } In your startup.cs you have something in … Read more
First, you need to add a custom XML namespace that will design the namespace where the settings are defined: xmlns:properties=”clr-namespace:TestSettings.Properties” Then, in your XAML file, access the default settings instance using the following syntax: {x:Static properties:Settings.Default} So here is the final result code: <ListBox x:Name=”lb” ItemsSource=”{Binding Source={x:Static properties:Settings.Default}, Path=Names}” /> Source: WPF – How to … Read more
I know I’m late 🙂 But this how i do it: public static void AddOrUpdateAppSettings(string key, string value) { try { var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); var settings = configFile.AppSettings.Settings; if (settings[key] == null) { settings.Add(key, value); } else { settings[key].Value = value; } configFile.Save(ConfigurationSaveMode.Modified); ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name); } catch (ConfigurationErrorsException) { Console.WriteLine(“Error writing app settings”); } } … Read more
STEP 1: Include the following in OnConfiguring() protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) { IConfigurationRoot configuration = new ConfigurationBuilder() .SetBasePath(AppDomain.CurrentDomain.BaseDirectory) .AddJsonFile(“appsettings.json”) .Build(); optionsBuilder.UseSqlServer(configuration.GetConnectionString(“DefaultConnection”)); } STEP 2: Create appsettings.json: { “ConnectionStrings”: { “DefaultConnection”: “Server=YOURSERVERNAME; Database=YOURDATABASENAME; Trusted_Connection=True; MultipleActiveResultSets=true” } } STEP 3: Hard copy appsettings.json to the correct directory Hard copy appsettings.json.config to the directory specified in the … Read more
This is based on the blog post Using Configuration files in .NET Core Unit Test Projects (written for .NET Core 1.0). Create (or copy) the appsettings.test.json in the Integration test project root directory, and in properties specify “Build Action” as Content and “Copy if newer” to Output Directory. Note that it’s better to have file … Read more
MSDN: Configuration Manager.AppSettings if (ConfigurationManager.AppSettings[name] != null) { // Now do your magic.. } or string s = ConfigurationManager.AppSettings[“myKey”]; if (!String.IsNullOrEmpty(s)) { // Key exists } else { // Key doesn’t exist }
Update for .NET Core 3.0+ You can use CreateDefaultBuilder which will automatically build and pass a configuration object to your startup class: WebHost.CreateDefaultBuilder(args).UseStartup<Startup>(); public class Startup { public Startup(IConfiguration configuration) // automatically injected { Configuration = configuration; } public IConfiguration Configuration { get; } /* … */ } CreateDefaultBuilder automatically includes the appropriate appsettings.Environment.json file … Read more
This works for me: string value = System.Configuration.ConfigurationManager.AppSettings[key];
As mentioned by Karan Dua this is now possible in iOS8 using UIApplicationOpenSettingsURLString see Apple’s Documentation. Example: Swift 4.2 UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!) In Swift 3: UIApplication.shared.open(URL(string:UIApplicationOpenSettingsURLString)!) In Swift 2: UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!) In Objective-C [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]]; Prior to iOS 8: You can not. As you said this has been covered many times and that pop up … Read more
Program and Startup class .NET Core 2.x You don’t need to new IConfiguration in the Startup constructor. Its implementation will be injected by the DI system. // Program.cs public class Program { public static void Main(string[] args) { BuildWebHost(args).Run(); } public static IWebHost BuildWebHost(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .Build(); } // Startup.cs public class Startup … Read more
