如何在自定义ConfigurationProvider中访问DI

public class CustomConfigurationProvider : ConfigurationProvider
{
    private readonly IServiceProvider _serviceProvider;

    public CustomConfigurationProvider(IServiceProvider serviceProvider)
    {
        _serviceProvider = serviceProvider;
    }

    // 实现ConfigurationProvider的Load方法和其他必要的方法
    // ...
}

public class CustomConfigurationProvider : ConfigurationProvider
{
    private readonly IServiceProvider _serviceProvider;

    public CustomConfigurationProvider(IServiceProvider serviceProvider)
    {
        _serviceProvider = serviceProvider;
    }

    public override void Load()
    {
        var myService = _serviceProvider.GetService<MyService>();
        // 使用myService进行配置数据的加载
        // ...
    }
}

var serviceProvider = new ServiceCollection()
    .AddSingleton<MyService>()
    .BuildServiceProvider();

var configuration = new ConfigurationBuilder()
    .Add(new CustomConfigurationSource(serviceProvider))
    .Build();
