Question

我正在尝试更新我的代码以使用最新版本的Simple Injector。

旧代码：

container.RegisterOpenGeneric(
    typeof(ISolrAbstractResponseParser<>), 
    typeof(DefaultResponseParser<>));

新代码，无效：

container.Register(typeof(ISolrAbstractResponseParser<>), new[]
{
    typeof(ISolrAbstractResponseParser<>).Assembly,
    typeof(MultiResponseParser<>).Assembly
});

出现此错误：

SimpleInjector.ActivationException was unhandled by user code
  HResult=-2146233088
  Message=The constructor of type SolrOperationsFactory<LemmaDocument> contains the parameter with name 'responseParser' and type ISolrAbstractResponseParser<LemmaDocument> that is not registered. 
  Please ensure ISolrAbstractResponseParser<LemmaDocument> is registered, or change the constructor of SolrOperationsFactory<LemmaDocument>.

接口在SolrNet中声明，但在我的代码中使用。

container.RegisterOpenGeneric已从Simple Injector中删除。 Link to documentation

Simple Injector在这个类中失败了：

/// <summary>
    /// An adapter for SolrNet.Impl.SolrMoreLikeThisHandlerQueryResultsParser to work around a limitation in SimpleInjector where
    /// arrays of open generic types cannot be injected.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class SolrMoreLikeThisHandlerQueryResultsParserAdapter<T> : SolrMoreLikeThisHandlerQueryResultsParser<T>
    {
        public SolrMoreLikeThisHandlerQueryResultsParserAdapter(IEnumerable<ISolrAbstractResponseParser<T>> parsers) : base(parsers.ToArray())
        {
        }
    }

Simple Injector和注入开放泛型类型的数组是否仍有问题？

***** 我放弃更新我的项目以使用Simple Injector =＆gt; 3.0 ***** 我应该删除这个问题吗？

正如您已经说过的，编译器错误说明：

此扩展方法已被删除。请使用Container.Register（Type，Type）注册泛型类型。如果此注册充当后备注册（如果缺少明确的注册），请使用Container.RegisterConditional（Type，Type，c =＆gt;！c.Handled）。

长话短说，将RegisterOpenGeneric的来电替换为Register，如下一个示例所示：

container.Register(
    typeof(ISolrAbstractResponseParser<>), 
    typeof(DefaultResponseParser<>));

使用Simple Injector注册ISolrAbstractResponseParser＆lt;＆gt;
