c# – NuGet的Unity Bootstrapper在App_Start上抛出错误

FilterProviders.Providers.Add(new UnityFilterAttributeFilterProvider(container));

出现以下错误：

An exception of type ‘System.ArrayTypeMismatchException’ occurred in
mscorlib.dll but was not handled in user code

Additional information: Attempted to access an element as a type
incompatible with the array.

整个代码都在这里,而且这是由nuget下载的引导程序预先制作和编写的.
