Question

我正在为我的DI / IOC项目添加结构图。在将其添加到我的应用程序之前，我构建了一个演示项目以熟悉它。在演示中使用它后，我开始将它移动到我的应用程序中。

我也使用glimpse，这似乎是自结构图添加（到目前为止）以来唯一导致问题的因素。

我遵循了一个非常基本的SM教程和NuGet包，此时我甚至没有注入任何依赖项。把一切都搞定了。

这是我的application_start

    IContainer container = new Container(x =>
    {
        x.For<IControllerActivator>().Use<StructureMapControllerActivator>();

    });

    DependencyResolver.SetResolver(new SmDependencyResolver(container));

如果我禁用一瞥，我的应用程序就像以前一样工作。我准备开始做DI了。但如果我启用了glimpse，我会得到一个null对象异常。这是堆栈跟踪，我跟着它没有太多运气。

System.NullReferenceException: Object reference not set to an instance of an object.

Answer 1

根据您的callstack，看起来您使用的是较早版本的Glimpse。

此错误已在Glimpse版本0.85中修复，现已在NuGet和CodePlex上提供。升级应该可以解决您的问题。

一起使用glimpse和structuremap
