Unity CS0308错误

Question

我刚刚开始使用 WPF 和 Unity 从实现 MVVM 架构的重要资源构建应用程序。我几乎完全遵循它并查看了他们使用的源代码，一切都几乎相同。我创建了一个 class ContainerHelper class:

private static IUnityContainer _container;
        static ContainerHelper()
        {
            _container = new UnityContainer();
            _container.RegisterType<IEmployeesRepository, EmployeesRepository>(
                new ContainerControlledLifetimeManager());
        }

        public static IUnityContainer Container
        {
            get { return _container; }
        }

并且我创建了一个 class EmployeeListViewModel：

私有 IEmployeesRepository _repo；

public EmployeeListViewModel(IEmployeesRepository repo)
{
    _repo = repo;
    EditEmployeeCommand = new RelayCommand<Employees>(OnEditEmployee);
    AddEmployeeCommand = new RelayCommand(OnAddEmployee);
    ClearSearchCommand = new RelayCommand(OnClearSearch);
}

private string _SearchInput;

public string SearchInput
{
    get { return _SearchInput; }
    set
    {
        SetProperty(ref _SearchInput, value);
        FilterEmployee(_SearchInput);
    }
}

private void FilterEmployee(string searchInput)
{
    if (string.IsNullOrWhiteSpace(searchInput))
    {
        Employees = new ObservableCollection<Employees>(_allEmployees);
    }
    else
    {
        Employees = new ObservableCollection<Employees>(_allEmployees.Where(e => e.FullName.ToLower().Contains(searchInput.ToLower())));
    }
}

private void OnClearSearch()
{
    SearchInput = null;
}

private void OnEditEmployee(Employees emp)
{
    EditEmployeeRequest(emp);
}

private void OnAddEmployee()
{
    AddEmployeeRequested(new Employees { Id = Guid.NewGuid() });
}

public event Action<Employees> AddEmployeeRequested = delegate { };
public event Action<Employees> EditEmployeeRequest = delegate { };

private ObservableCollection<Employees> _Employees;
public ObservableCollection<Employees> Employees
{
    get { return _Employees; }
    set { SetProperty(ref _Employees, value); }
}

private List<Employees> _allEmployees;
public async void LoadEmplooyees()
{
    _allEmployees = await _repo.GetEmployeesAsync();
    Employees = new ObservableCollection<Employees>(_allEmployees);
}

public RelayCommand<Employees> EditEmployeeCommand { get; private set; }
public RelayCommand AddEmployeeCommand { get; private set; }
public RelayCommand ClearSearchCommand { get; private set; }

}

这是使用 ContainerHelper 实现和传递 EmployeeListViewModel 的代码行 class:

private EmployeeListViewModel _EmployeeListViewModel;
 _EmployeeListViewModel = ContainerHelper.Container.Resolve<EmployeeListViewModel>();

我不明白为什么使用 IUnityContainer.Resolve(type, sring, params ResolverOverride[]) cannot be used with type arguments.

时出现非泛型方法错误

我想了解更多关于这个错误的信息以及我可以做些什么来修复它...我已经在各个地方寻找答案。

在调用通用 Resolve 方法的代码文件顶部添加以下 using 指令：

using Microsoft.Practices.Unity;
