Microsoft.Extensions.Configuration.Json 8.0.0

About

JSON configuration provider implementation for Microsoft.Extensions.Configuration. This package enables you to read your application's settings from a JSON file. You can use JsonConfigurationExtensions.AddJsonFile extension method on IConfigurationBuilder to add the JSON configuration provider to the configuration builder.

How to Use

The following example shows how to read application settings from the JSON configuration file.

using System;
using Microsoft.Extensions.Configuration;

class Program
{
    static void Main()
    {
        // Build a configuration object from JSON file
        IConfiguration config = new ConfigurationBuilder()
            .AddJsonFile("appsettings.json")
            .Build();

        // Get a configuration section
        IConfigurationSection section = config.GetSection("Settings");

        // Read simple values
        Console.WriteLine($"Server: {section["Server"]}");
        Console.WriteLine($"Database: {section["Database"]}");

        // Read a collection
        Console.WriteLine("Ports: ");
        IConfigurationSection ports = section.GetSection("Ports");

        foreach (IConfigurationSection child in ports.GetChildren())
        {
            Console.WriteLine(child.Value);
        }
    }
}

To run this example, include an appsettings.json file with the following content in your project:

{
  "Settings": {
    "Server": "example.com",
    "Database": "Northwind",
    "Ports": [ 80, 81 ]
  }
}

You can include a configuration file using a code like this in your .csproj file:

<ItemGroup>
  <Content Include="appsettings.json">
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </Content>
</ItemGroup>
