如何将appsetting.json配置文件中的IConfiguration注入到他的代码中？

using Microsoft.Extensions.Configuration;

public class MyClass
{
    private readonly IConfiguration _configuration;

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

    // 其他代码...
}

using Microsoft.Extensions.Configuration;

public class Startup
{
    private readonly IConfiguration _configuration;

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

    public void ConfigureServices(IServiceCollection services)
    {
        // 将IConfiguration注册为服务，以便在其他地方进行注入
        services.AddSingleton(_configuration);

        // 其他服务的注册...
    }

    // 其他代码...
}

public class MyClass
{
    private readonly IConfiguration _configuration;

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

    public void SomeMethod()
    {
        // 获取配置值
        string value = _configuration["Key"];

        // 使用配置值进行其他操作...
    }
}
