Custom configurationprovider in asp net core ado net

Introduction

ASP.NET is a popular programming language used for building web applications. One of the key features of ASP.NET is its ability to configuration providers. In this article, we will explore how to create a custom configuration provider in ASP.NET Core using ADO.NET.

Understanding Configuration Providers

Configuration providers in ASP.NET Core are responsible for retrieving configuration data from sources, such as JSON , environment variables, or databases. By default, ASP.NET Core provides built-in configuration providers for these sources. However, there may be scenarios where you need to create a custom configuration provider to fetch data from a different source.

Creating a Custom Configuration Provider

To create a custom configuration provider in ASP.NET Core using ADO.NET, you need to follow these steps:

Step 1: a Configuration Provider

Create a new class that inherits from the ConfigurationProvider class. This class will be responsible for data from the database and populating the configuration.


public class CustomConfigurationProvider : ConfigurationProvider
{
    public override void Load()
    {
        // Fetch data from the database and populate the configuration
    }
}

Step 2: Register the Configuration Provider

In your ASP.NET Core 's Startup class, register the custom configuration provider in the ConfigureServices method.


public void ConfigureServices(IServiceCollection services)
{
    // Other service registrations

    services.AddSingleton();
}

Step 3: Use the Custom Configuration Provider

Now that the custom configuration provider is registered, you can use it in your application. For example, you can access configuration values in your controllers or services using the IConfiguration interface.


public class HomeController : Controller
{
    private readonly IConfiguration _configuration;

    public HomeController(IConfiguration configuration)
    {
        _configuration = configuration;
    }

    public IActionResult ()
    {
        var value = _configuration["Key"];

        // Rest of the code
    }
}

Conclusion

In this article, we have learned how to create a custom configuration provider in ASP.NET Core using ADO.NET. By following the steps outlined above, you can fetch configuration data from a database and use it in your application. Custom configuration providers provide flexibility and you to integrate ASP.NET Core with various data sources.
