About

Microsoft.Extensions.Options provides a strongly typed way of specifying and accessing settings using dependency injection and acts as a bridge between configuration, DI, and higher level libraries. This library is the glue for how an app developer uses DI to configure the behavior of a library like HttpClient Factory. This also enables user to get a strongly-typed view of their configuration.

Within this package, you'll find an options validation source generator that generates exceptionally efficient and optimized code for validating options.

Key Features

Offer the IValidateOptions interface for the validation of options, along with several generic ValidateOptions classes that implement this interface.
OptionsBuilder to configure options.
Provide extension methods for service collections and options builder to register options and validate options.
Supply a set of generic ConfigureNamedOptions classes that implement the IConfigureNamedOptions interface for configuring named options.
Provide a source generator that generates validation code for options.
Options caching, managing and monitoring.

How to Use

Options validation example

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Options;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddControllersWithViews();

// Load the configuration and validate it
builder.Services.AddOptions<MyConfigOptions>()
            .Bind(builder.Configuration.GetSection(MyConfigOptions.MyConfig))
            .ValidateDataAnnotations();
var app = builder.Build();


// Declare the option class to validate
public class MyConfigOptions
{
    public const string MyConfig = "MyConfig";

    [RegularExpression(@"^[a-zA-Z''-'\s]{1,40}$")]
    public string Key1 { get; set; }
    [Range(0, 1000,
        ErrorMessage = "Value for {0} must be between {1} and {2}.")]
    public int Key2 { get; set; }
    public int Key3 { get; set; }
}

Using IValidateOptions to validate options

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Options;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddControllersWithViews();

// Configuration to validate
builder.Services.Configure<MyConfigOptions>(builder.Configuration.GetSection(
                                        MyConfigOptions.MyConfig));

// OPtions validation through the DI container
builder.Services.AddSingleton<IValidateOptions
                              <MyConfigOptions>, MyConfigValidation>();

var app = builder.Build();

public class MyConfigValidation : IValidateOptions<MyConfigOptions>
{
    public MyConfigOptions _config { get; private set; }

    public  MyConfigValidation(IConfiguration config)
    {
        _config = config.GetSection(MyConfigOptions.MyConfig)
            .Get<MyConfigOptions>();
    }

    public ValidateOptionsResult Validate(string name, MyConfigOptions options)
    {
        string? vor = null;
        var rx = new Regex(@"^[a-zA-Z''-'\s]{1,40}$");
        var match = rx.Match(options.Key1!);

        if (string.IsNullOrEmpty(match.Value))
        {
            vor = $"{options.Key1} doesn't match RegEx \n";
        }

        if ( options.Key2 < 0 || options.Key2 > 1000)
        {
            vor = $"{options.Key2} doesn't match Range 0 - 1000 \n";
        }

        if (_config.Key2 != default)
        {
            if(_config.Key3 <= _config.Key2)
            {
                vor +=  "Key3 must be > than Key2.";
            }
        }

        if (vor != null)
        {
            return ValidateOptionsResult.Fail(vor);
        }

        return ValidateOptionsResult.Success;
    }
}

Options Validation Source Generator Example

using System;
using System.ComponentModel.DataAnnotations;
using Microsoft.Extensions.Options;

public class MyConfigOptions
{
    [RegularExpression(@"^[a-zA-Z''-'\s]{1,40}$")]
    public string Key1 { get; set; }

    [Range(0, 1000,
        ErrorMessage = "Value for {0} must be between {1} and {2}.")]
    public int Key2 { get; set; }
    public int Key3 { get; set; }
}

[OptionsValidator]
public partial class MyConfigValidation : IValidateOptions<MyConfigOptions>
{
    // Source generator will automatically provide the implementation of IValidateOptions
    // Then you can add the validation to the DI Container using the following code:
    //
    // builder.Services.AddSingleton<IValidateOptions
    //                          <MyConfigOptions>, MyConfigValidation>();
    // builder.Services.AddOptions<MyConfigOptions>()
    //        .Bind(builder.Configuration.GetSection(MyConfigOptions.MyConfig))
    //        .ValidateDataAnnotations();
}
