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>IAccounRepository.cs
1.
namespace WcfService1.Model
{
public interface IAccountRepository
{
IEnumerable<Account> GetAllRows();
bool AddAccount(Account item);
}
}
模型>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 > EntityFramework + DbContext
IService1.cs
代码：
namespace WcfService1
{
[ServiceContract(SessionMode = SessionMode.Allowed)]
public interface IService1
{
[OperationContract]
IList<Account> GetAccounts();
[OperationContract]
bool AddAccount(Account item);
}
}
- 服务1.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);
}
}
}
- 服务1.svc
代码：
<%@ ServiceHost Language="C#"
Debug="true"
Service="WcfService1.Service1, WcfService1"
Factory="Autofac.Integration.Wcf.AutofacWebServiceHostFactory, Autofac.Integration.Wcf" %>
- 全球.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，找不到解决方案。我怎么了。
