В моем проекте в некоторых репозиториях я передаю ISession (nHibernate) и другим connectionString для DataContext (Linq2SQL)
Для передачи строки подключения я создал класс LinqConfiguration
public class LinqConfiguration : ILinqConfiguration
{
private readonly string _connectionString;
public LinqConfiguration(string connectionString)
{
_connectionString = connectionString;
}
public string GetConnectionString()
{
return _connectionString;
}
}
Myрепозиторий выглядит так:
public class WebClientRepository : IWebClientRepository
{
private readonly WebClientDataClassesDataContext datacontext;
private ILinqConfiguration _linqconfig;
public WebClientRepository(ILinqConfiguration linqconfig)
{
_linqconfig = linqconfig;
datacontext = new WebClientDataClassesDataContext(_linqconfig.GetConnectionString());
}
//....
}
и привязка с использованием соглашений:
public class LinqRepositoryModule: NinjectModule
{
public override void Load()
{
Bind<ILinqConfiguration>()
.To<LinqConfiguration>()
.WithConstructorArgument("connectionString",
ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString
);
IKernel ninjectKernel = this.Kernel;
ninjectKernel.Scan(kernel =>
{
kernel.FromAssemblyContaining<IWebClientRepository>();
kernel.FromAssemblyContaining<WebClientRepository>();
kernel.Where(t => t != typeof(LinqConfiguration)); // interface is in the same assembly and it is already binded
kernel.BindWithDefaultConventions();
kernel.AutoLoadModules();
kernel.InRequestScope();
});
}
}
