在c#控制台应用程序中设置结构映射

我收到了这个错误:

StructureMap Exception Code:  202
No Default Instance defined for PluginFamily 

我的设置如下:

Console.WriteLine("Structure Map");
SetupSM sm = new SetupSM();
sm.Setup();

ISomeThing someThing = ObjectFactory.GetInstance<ISomeThing>();
Console.WriteLine("something.HowManyTHings: " + someThing.HowManyThings("asdf"));



 public class SetupSM
    {
        public void Setup()
        {
            var c1 = new Container(config =>
            {
                config.Scan(scan =>
                {
                    scan.TheCallingAssembly();
                    scan.WithDefaultConventions();
                });
            });

            var c2 = new Container(x =>
                                              {
                                                  x.For<ISomeThing>().Use<SomeThingOne>();
                                              });


        }
    }

这是我第一次尝试使用结构图,我错过了什么? 看来他们主网站上的指南使用旧语法等很老了。

尝试将您的配置应用于静态ObjectFactory,而不是立即丢弃的单独容器。

public class SetupSM
    {
        public void Setup()
        {
            ObjectFactory.Configure(config =>
            { 
                config.Scan(scan =>
                {
                    scan.TheCallingAssembly();
                    scan.WithDefaultConventions();
                });

                config.For<ISomething>().Use<SomeThingOne>();
            });
    }

以前的答案适用于StructureMap 2或3,但在StructureMap 4中语法已更改。您可以在此处查看完整的解决方案:

实际上,ObjectFactory已被Container实例取代。您还可以选择在单独的Registry实例中执行配置,建议使用此实例。因此,Main()中的初始化代码变为:

static void Main(string[] args)
{
    var container = Container.For<ConsoleRegistry>();

    var app = container.GetInstance<Application>();
    app.Run();
    Console.ReadLine();
}

这使Main非常干净,并允许Application通过dependency injection请求所需的任何依赖项,并遵循Explicit Dependencies Principle。这些组合使您的应用程序非常易于组合和可测试。

public static class StructureMapBootStrapper
{
    public static void BootStrap()
    {
        StructureMap.ObjectFactory.Initialize(
            bootStrapper =>
            {
                bootStrapper.For<ISomeThing>().Use<SomeThingOne>();
            });
    }
}

您的控制台应用:

Console.WriteLine("Structure Map");
StructureMapBootStrapper.BootStrap();

ISomeThing someThing = ObjectFactory.GetInstance<ISomeThing>();
Console.WriteLine("something.HowManyTHings: " + someThing.HowManyThings("asdf"));
