Unity CS0308错误

Question

我刚刚开始使用WPF和Unity构建应用程序，这是一个实现MVVM架构的优秀来源。我跟着它几乎相同，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ContainerHelper类：

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

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

我创建了一个类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类实现和传递EmployeeListViewModel的代码行：

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

我不明白为什么我使用IUnityContainer获取非泛型方法错误.Resolve（type，sring，params ResolverOverride []）不能与类型参数一起使用。

我想更多地了解这个错误以及我可以做些什么来解决它...我已经在各个地方寻找答案。

在您调用通用using方法的代码文件顶部添加以下Resolve指令：

using Microsoft.Practices.Unity;
