Question

我正在尝试在Wcf上尝试使用Autofac的结构。

    namespace WcfService1.Model
    {
        [DataContract(IsReference = true)]
        public partial class Account
        {
            [DataMember]
            public int Id { get; set; }
            [DataMember]
            public string Name { get; set; }
            [DataMember]
            public string Surname { get; set; }
            [DataMember]
            public string Email { get; set; }
            [DataMember]
            public Nullable<System.DateTime> CreateDate { get; set; }
        }    
    }

模型＆GT; IAccounRepository.cs

1

namespace WcfService1.Model
{
  public interface IAccountRepository
    {
        IEnumerable<Account> GetAllRows();
        bool AddAccount(Account item);
    }
}

模型＆GT; AccounRepository.cs

2

namespace WcfService1.Model
{
    public class AccountRepository:IAccountRepository
    {
        private Database1Entities _context;
        public AccountRepository()
        {
            if(_context == null)
                _context =new Database1Entities();
        }

        public IEnumerable<Account> GetAllRows()
        {
            if (_context == null)
                _context = new Database1Entities();
            return _context.Account.AsEnumerable();
        }        

        public bool AddAccount(Account item)
        {
            try
            {
                if (_context == null)
                    _context = new Database1Entities();
                _context.Entry(item).State = EntityState.Added;
                _context.Account.Add(item);
                _context.SaveChanges();
                return true;
            }
            catch (Exception ex)
            {
                var str = ex.Message;
                return false;
            }
        }
    }
}

DbConnection＆gt; EntityFramework + DbContext
IService1.cs

代码：

namespace WcfService1
{
    [ServiceContract(SessionMode = SessionMode.Allowed)]
    public interface IService1
    {
        [OperationContract]
        IList<Account> GetAccounts();

        [OperationContract]
        bool AddAccount(Account item);
    }
}

Service1.cs

代码：

namespace WcfService1
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service1:IService1
    {
        private readonly IAccountRepository _repository;
        public Service1(IAccountRepository repository)
        {
            _repository = repository;
        }    
        public IList<Account> GetAccounts()
        {   
            var items = _repository.GetAllRows().ToList();
            return items;
        }
        public bool AddAccount(Account item)
        {
            item.CreateDate = DateTime.Now;    
            return _repository.AddAccount(item);
        }
    }
}

Service1.svc

代码：

<%@ ServiceHost Language="C#"
                Debug="true"
                Service="WcfService1.Service1, WcfService1"
                Factory="Autofac.Integration.Wcf.AutofacWebServiceHostFactory, Autofac.Integration.Wcf" %>

Global.asax.cs

代码：

protected void Application_Start(object sender, EventArgs e)
        {
            var builder = new ContainerBuilder();
            builder.RegisterType< AccountRepository>().As< IAccountRepository>();
            builder.RegisterType< Service1 >().As< IService1>();

            AutofacHostFactory.Container = builder.Build();
        }

我收到以下错误，无法找到解决方案。我错了。

Answer 1

除了其他答案之外，您还应确保在.svc文件中的ServiceHost元素的Service属性中使用完全限定的服务名称。

例如，而不是：

<%@ ServiceHost Language="C#" Debug="true" Service="MoviesService.MoviesService" CodeBehind="MoviesService.svc.cs" %>

使用：

<%@ ServiceHost Language="C#" Debug="true" Service="MoviesService.MoviesService, MoviesService" CodeBehind="MoviesService.svc.cs" %>

Answer 2

您应该将服务注册为self，而不是接口。

builder.RegisterType< Service1 >().AsSelf();

Answer 3

只需注册Service1，就像builder.RegisterType<Service1>(); builder.RegisterType<Service1>().As<IService1>();

一样

Answer 4

尝试一下：

var builder = new ContainerBuilder();

builder.Register(c => new AccountRepository()).As<IAccountRepository>();
builder.Register(c => new Service1(c.Resolve<IAccountRepository>())).AsSelf();

AutofacHostFactory.Container = builder.Build();

Answer 5

你不应该使用。 `builder.RegisterType＆LT; Service1＆gt;（）。作为' 但是使用RegisterType而不使用扩展方法 'builder.RegisterType（）;'

Answer 6

对我而言，我使用的是名为“WCF服务”的项目

默认情况下，这给了我一个名为WCF_Service的名称空间，以及一个名为＆＃39; WCF Service＆＃39;

的程序集名称

在删除该空格之前，没有任何修复工作。

Answer 7

您应该在.svc文件（Namespace1）中写入：

<%@ ServiceHost Language="C#" Debug="true" Service="Namespace1.Service1, Namespace1"
   Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf" CodeBehind="Service1.svc.cs" %>
