Using strongly-typed configurations in. NET Core Console applications

Imagine that you write a console application and you want to read the configuration in a strongly typed manner from the configuration file.

. NET Core can help us solve. I will usually demonstrate in ASP. NET Core MVC, but for simplicity, only in console applications.

Let's create two configuration classes to hold the application and module names.

 Public class mysettings{    publicstringgetset;}  Public class mymodulesettings{    publicstringgetset;}

The application configuration file looks like this:

{  "ApplicationName""My sample application" ,   " Sectiona " : {    "modulename" "My Sample module"   }}

Finally, let's use it in the application.

 Public classprogram{ Public Static voidMain (string[] args) {        varBuilder =NewConfigurationbuilder (). Setbasepath (Directory.GetCurrentDirectory ()). Addjsonfile ("Appsettings.json", Optional:false, Reloadonchange:true)            .        Addenvironmentvariables (); Iconfigurationroot Configuration=Builder.        Build (); varSettings =Newmysettings (); Configuration.        Bind (settings); varModulesettings =Newmymodulesettings (); Configuration. GetSection ("Sectiona").        Bind (modulesettings); Console.WriteLine ($"My application name is ' {settings. ApplicationName} '"); Console.WriteLine ($"My Module name is ' {modulesettings.modulename} '");    Console.ReadLine (); }}

All implementations are through the "Bind" method.

Don't forget to add the required dependencies. Project.json should contain the following content:

{  "version":"1.0.0-*",  "buildoptions": {    "Emitentrypoint":true  },  "Dependencies": {    "Microsoft.Extensions.Configuration":"1.1.0",    "Microsoft.Extensions.Configuration.Binder":"1.1.0",    "Microsoft.Extensions.Configuration.EnvironmentVariables":"1.1.0",    "Microsoft.Extensions.Configuration.FileExtensions":"1.1.0",    "Microsoft.Extensions.Configuration.Json":"1.1.0",    "Microsoft.NETCore.App": {      "type":"Platform",      "version":"1.0.1"    }  },  "Frameworks": {    "netcoreapp1.0": {      "Imports":"Dnxcore50"    }  }}

Operation Result:

Using a strongly typed configuration class in a. NET core application is easy! Hope this article is helpful to you ~.
