Question

它正在寻找的控制器名称是正确的名称，我知道容器中的导出具有匹配的名称。由于某种原因，它找不到它。我试图从dll导入我已放入项目中的指定文件夹。它总是会尝试返回默认控制器，但找不到dll控制器，因为它不在主项目目录中。我知道controllerFactory找到了DLL，但没有正确读取它。

这是我的CreateController功能：

Public Function CreateController(requestContext As System.Web.Routing.RequestContext, 
        controllerName As String) As System.Web.Mvc.IController Implements 
        System.Web.Mvc.IControllerFactory.CreateController





    Dim controller As IController = Nothing

    If controllerName IsNot Nothing Then



        Dim controllerClassName As String = controllerName & "Controller"




       Dim controllers As IEnumerable(Of Lazy(Of IController)) = Me.container.GetExports(Of IController)()

        Dim controllerExport As Lazy(Of IController) = controllers _
                                             .Where(Function(c) c.Value.GetType.Name = controllerName) _
                                             .FirstOrDefault()



        If export IsNot Nothing Then
            controller = export.Value
        End If

    End If

    If controller Is Nothing Then
        Return Me.defaultControllerFactory.CreateController(requestContext, controllerName)
    End If

    Return controller

End Function

如果您需要澄清任何内容，请告诉我们！谢谢！

编辑：返回Me.defaultControllerFactory.CreateController（requestContext，controllerName）上的错误消息是HttpException未被用户代码处理。未找到控制器路径“CUContractNumberPlugin / ChangeCUNumber”或未实现IController。

这是它正在谈论的控制器。

<Export(GetType(IController)), ExportMetadata("Name", "CUContractNumberPlugin")> _
Public Class CUContractNumberPluginController
    Inherits Controller

    <Import(GetType(IHost))>
    Private m_hostApp As IHost


    Public Function Index() As ActionResult
        Return View()
    End Function

    Function ChangeCUNumber(strCUNumber As String) As ActionResult
        m_hostApp.CUNumber = strCUNumber
        Return View("Index", m_hostApp)
    End Function

End Class

当我将部分视图加载到主视图中时，会调用此方法。局部视图是这样的：

@Using (Html.BeginForm("ChangeCUNumber", "CUContractNumberPlungin"))

    @Html.TextBox("strCUNumber")

End Using

自定义控制器工厂找不到导出
