namespace PageNavigation.Services
{
public interface INavigationService
{
void NavigateToPage1();
void NavigateToPage2();
}
}
using System.Windows.Controls;
using PageNavigation.Pages;
namespace PageNavigation.Services
{
public class NavigationService : INavigationService
{
private readonly Frame _frame;
public NavigationService(Frame frame)
{
_frame = frame;
}
public void NavigateToPage1()
{
_frame.Navigate(new Page1());
}
public void NavigateToPage2()
{
_frame.Navigate(new Page2());
}
}
}
Такой Ioc:
using System.Windows.Controls;
namespace PageNavigation.Services
{
public static class Ioc
{
public static INavigationService NavigationService { get; private set; }
public static void Init(Frame frame)
{
NavigationService = new NavigationService(frame);
}
}
}
Или такой Ioc:
https://autofac.org/
using System.Windows.Controls;
using Autofac;
namespace PageNavigation.Services
{
public static class Ioc
{
private static IContainer _container;
public static INavigationService NavigationService
{
get { return _container.Resolve<INavigationService>(); }
}
//public static MainViewModel MainViewModel
//{
// get { return _container.Resolve<MainViewModel>(); }
//}
public static void Init(Frame frame)
{
var builder = new ContainerBuilder();
builder.RegisterType<NavigationService>()
.As<INavigationService>()
.SingleInstance()
.WithParameter(new TypedParameter(typeof(Frame), frame));
//builder.RegisterType<MainViewModel>()
// .SingleInstance();
_container = builder.Build();
}
}
}
