谁能为下面的StuctureMap DI代码建议xml配置。 BrowserType是枚举数。

ObjectFactory.Initialize(x =>
{
    // Tell StructureMap to look for configuration
    // from the App.config file
    // The default is false
    //x.PullConfigurationFromAppConfig = true;
    x.For<ITranslatorEngine>().Use<Translator>().Ctor<BrowserType>().Is(BrowserType.IE);
});

最佳答案

我对StructureMap并不是很熟悉,所以我猜测,但是我认为您可以执行以下操作:

<StructureMap MementoStyle="Attribute">
  <DefaultInstance
    PluginType="assembly-qualified name of ITranslatorEngine"
    PluggedType="assembly-qualified name of Translator"
    browserType = "IE" />
</StructureMap>


假设“ browserType”是Translator类中构造函数参数的名称。

您可以将XML放在App.config文件或StructureMap.config中,然后修改ObjectFactory.Initialize调用以为config源设置适当的属性。

可在StructureMap网站上找到更多详细信息:

编辑:根据this page,枚举的字符串名称应用作值。


这是一个基于StructureMap 2.6.1的完整工作示例:

Translator.cs:

namespace StructureMapTests
{
    public interface ITranslator
    {
    }

    public enum BrowserType
    {
        IE,
        Firefox,
        Chrome
    }

    public class Translator : ITranslator
    {
        public Translator(BrowserType browserType)
        {

        }
    }
}


Program.cs:

namespace StructureMapTests
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                ObjectFactory.Initialize(x =>
                           {
                              x.PullConfigurationFromAppConfig = true;
                           });

                var translator = ObjectFactory.GetInstance<ITranslator>();

                Console.WriteLine(translator == null);
            }
            catch(Exception ex)
            {
                Console.WriteLine(ex);
            }

            Console.ReadLine();
        }
    }
}


App.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="StructureMap" type="StructureMap.Configuration.StructureMapConfigurationSection,StructureMap"/>
  </configSections>

  <StructureMap MementoStyle="Attribute">
    <DefaultInstance PluginType="StructureMapTests.ITranslator, StructureMapTests"
                     PluggedType="StructureMapTests.Translator, StructureMapTests"
                     browserType="IE">

    </DefaultInstance>
  </StructureMap>
</configuration>
