使用 Prism Scultpure 我正面临这个问题
有人可以帮我做什么。我有 R1 区域,但它会引发以下错误
以下代码中的粗体行是错误
public virtual void StartAction()
{
global::System.ComponentModel.BackgroundWorker backgroundWorker = new global::System.ComponentModel.BackgroundWorker();
backgroundWorker.WorkerReportsProgress = true;
backgroundWorker.DoWork += new global::System.ComponentModel.DoWorkEventHandler(this.StartActionWorker);
backgroundWorker.RunWorkerAsync();
CandidateView candidateView = null;
foreach (object view in **this.RegionManager.Regions["R1"].Views**)
{
if (true == view is CandidateView)
{
candidateView = view as CandidateView;
break;
}
}
if (null == candidateView)
{
candidateView = this.Container.GetExportedValue<CandidateView>();
this.RegionManager.Regions["R1"].Add(candidateView);
}
this.RegionManager.Regions["R1"].Activate(candidateView);
}
合成产生了一个单一的合成错误。下面提供了根本原因。查看 CompositionException.Errors 属性以获取更多详细信息。1) 区域管理器不包含 R1 区域。导致:初始化模块“CandidateMModule”时发生异常。- 异常消息是:区域管理器不包含 R1 区域。- 试图从中加载模块的程序集是:Candidate,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null 检查异常的 InnerException 属性以获取更多信息。如果在 DI 容器中创建对象时发生异常,您可以通过 exception.GetRootException() 来帮助定位问题的根本原因。导致:在类型“Microsoft”上调用“OnImportsSatisfied”方法时发生异常。实践.Prism.MefExtensions.Modularity.MefModuleManager'。导致:无法激活部件“Microsoft.Practices.Prism.MefExtensions.Modularity.MefModuleManager”。元素:Microsoft.Practices.Prism.MefExtensions.Modularity.MefModuleManager --> Microsoft.Practices.Prism.MefExtensions.Modularity.MefModuleManager --> AssemblyCatalog (Assembly="Microsoft.Practices.Prism.MefExtensions, Version=4.0.0.0, Culture =neutral, PublicKeyToken=31bf3856ad364e35") 导致:无法从“Microsoft.Practices.Prism”部分导出“Microsoft.Practices.Prism.MefExtensions.Modularity.MefModuleManager (ContractName="Microsoft.Practices.Prism.Modularity.IModuleManager")” .MefExtensions.Modularity.MefModuleManager'。元素:Microsoft.Practices.Prism.MefExtensions.Modularity.MefModuleManager (ContractName="
