Autofac - 通过xml配置将实例传递给构造函数参数

Question

我有一个将MemoryCache作为构造函数参数的实现。

我的XML配置：

<autofac defaultAssembly="Test.Caching"> 
    <component name="memoryCache" 
     type="System.Runtime.Caching.MemoryCache, System.Runtime.Caching"> 
     <parameters> 
      <parameter name="name" value="TestCache"/> 
     </parameters> 
    </component> 

    <component type="My.Caching.TaskCache, Test.Caching" service="Test.Caching.ITaskCache" > 
     <parameters> 
      <parameter name="cache" value="testCache" /> 
     </parameters> 
    </component> 
</autofac> 

我使用Autofac.Configuration，并通过注册XML：

builder.RegisterModule(new ConfigurationSettingsReader("autofac", "<configPath>")); 

我获得以下错误：

System.Configuration.ConfigurationErrorsException: The type 'System.Runtime.Caching.MemoryCache, System.Runtime.Caching' could not be found. It may re 
quire assembly qualification, e.g. "MyType, MyAssembly".

我认为你需要为你声明的接口：

<component name="memoryCache" 
type="System.Runtime.Caching.MemoryCache, System.Runtime.Caching" 
service="your.interface.IMemoryCache, your.interface"
