C# 简单注入器-自定义WebViewPage

我有一个使用翻译的小应用程序（目前）。 我的翻译服务叫做翻译（ITranslator）

我的问题是我不想在每个控制器（返回一个视图）中检索这个类，所以我可以在视图中使用它

我在ListService中也遇到了类似的问题（在这里我存储了我所有的

SelectListItem

列表）

CustomWebViewPage

public abstract class CustomViewPage<TModel> : WebViewPage<TModel>
{
    readonly IScriptFactory scriptFactory;
    readonly IMembership membership;
    readonly IListService listService;
    readonly ITranslator translator;

    IHtmlString path;

    public IMembership Membership { get { return this.membership; } }
    public override IPrincipal User { get { return this.membership.User; } }
    public IListService Lists { get { return this.listService; } }
    public ITranslator Translator { get { return this.translator; } }

    public CustomViewPage(IScriptFactory scriptFactory, IMembership membership,
        IListService listService, ITranslator translator)
    {
        this.scriptFactory = scriptFactory;
        this.membership = membership;
        this.listService = listService;
        this.translator = translator;
    }

    public IHtmlString OwnScriptsPath
    {
        get { return path ?? (path = scriptFactory.Create(this.Html).ToHtmlString()); }
    }

    private string languageHtml =
        "<meta name=\"language\" content=\"" + membership.CurrentLanguage + "\">";
    public IHtmlString MetaLanguage { get { return MvcHtmlString.Create(languageHtml); } }
}

对于

InjectAttribute

我遵循了以下步骤。

您必须使用类似的寄存器依赖项容器。这样，当ASP.NET调用SimpleInput来解析依赖关系时，您可以指定所有接口以及匹配的实现

您还可以创建如下无参数构造函数：

public CustomViewPage() : base(new ScriptFactory(), new Membership()...) { }

---

但我不建议。。。最好的办法是让依赖项解析逻辑正常工作。

这可能与此相关：@StriplingWarrior我已经看到了带有注入属性的示例。但是simple injector没有提供它们，请向我们提供您所获得的异常的完整堆栈跟踪。@LeandroSoares:您不能为SimpleInjector定义一个使用默认构造函数的绑定，然后初始化这些属性吗？@Steven stacktrace添加
