Windows 表单应用程序中的 Autofac 容器

Question

我是 IoC 的新手，尤其是 Autofac。有几天我对 Windows 申请表中的 IoC 感到困惑。障碍是如何显示（如：Show、ShowDialog）已注册的表单。而IContainer只能本地访问（私有）Program.cs.

其实，在Windows申请表中可以使用IoC吗？我给出了一个让我困惑的示例代码。

#
# Demo.Core Project
#

namespace Demo.Core.Repository
{
    public interface IBaseRepository<T>
    {
        DbConnection CreateConnection();
        IEnumerable<T> Get(IDbTransaction transaction = null, int? commandTimeout = null);
    }

    public abstract class BaseRepository<T> : IBaseRepository<T> where T : class
    {
        public DbConnection CreateConnection()
        {
            return new SqlConnection("Data Source=localhost;User ID=sa;Password=Default!3;Initial Catalog=DemoIoC;");
        }

        public IEnumerable<T> Get(IDbTransaction transaction = null, int? commandTimeout = null)
        {
            using (var connection = CreateConnection())
                return connection.GetAll<T>(transaction, commandTimeout);
        }
    }

    public interface IUserRepository : IBaseRepository<User> { }
    public class UserRepository : BaseRepository<User>, IUserRepository { }
}

namespace Demo.Core.Models
{
    public class User
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
    }
}

#
# Demo.Winform Project
#

using Demo.Core.Models;
using Demo.Core.Repository;

namespace Demo.Winform
{
    static class Program
    {
        public static IContainer Container;

        [STAThread]
        static void Main()
        {
            Container = Configure();

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MainForm());
        }

        static IContainer Configure()
        {
            var builder = new ContainerBuilder();
            builder.RegisterType<UserRepository>().As<IUserRepository>();
            builder.RegisterType<UserManagerForm>();

            return builder.Build();
        }
    }


    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();

            button1.Click += new EventHandler(delegate (object sender, EventArgs e)
            {
                using (var container = *** HOW TO GET CONTAINER ? ***)
                {
                    Form manager = container.Resolve<UserManagerForm>();
                    manager.ShowDialog();
                }
            });
        }
    }

    public partial class UserManagerForm : Form
    {
        private readonly IUserRepository repository;
        public UserForm(IUserRepository repository) : this()
        {
            this.repository = repository;
        }

        public UserForm()
        {
            InitializeComponent();
        }

        protected override void OnShown(EventArgs e)
        {
            base.OnShown(e);

            listBox1.ValueMember = "Id";
            listBox1.DisplayMember = "Name";
            listBox1.DataSource = repository.Get();
        }
    }
}

我已阅读如何在容器中注册表单类型：Autofac - Register all Windows Forms。但是问题来了，我要如何解析注册的表单和show form？

谢谢。

这对我有用，你只需从容器中获取服务\

static class Program
{
    public static IContainer Container;
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Container = Configure();
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1(Container.Resolve<IWindowsFormsApp3Client>()));

    }
    static Autofac.IContainer Configure()
    {
        var builder = new ContainerBuilder();

        builder.Register<IWindowsFormsApp3Client>(ctor => new WindowsFormsApp3Client(new Uri("https://localhost:44381"), new CustomLoginCredentials()))
    .AsImplementedInterfaces();
      //  builder.RegisterType<WindowsFormsApp3Client>().As<IWindowsFormsApp3Client>();
        builder.RegisterType<Form1>();

     
        return builder.Build();
    }
}
public class CustomLoginCredentials : ServiceClientCredentials
{
    private string AuthenticationToken { get; set; }

    public override async Task ProcessHttpRequestAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
       // AuthenticationToken = Extensions.GetAppsettingsToken()?.AccessToken;
        if (AuthenticationToken != null)
        {
            request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", AuthenticationToken);
        }
        request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        await base.ProcessHttpRequestAsync(request, cancellationToken);

    }
}
