类型“CRM_BusinessLayer.MM_Purchasing”未定义._ [英] Type 'CRM_BusinessLayer.MM_Purchasing' is not defined._

问题描述

我遇到此错误的问题。

我是否需要安装或引用某些内容？

Do I have to install or reference something?

'declaration
Public Class POPrinting
    Inherits System.Web.UI.Page
    Private mobjCRMBAL As CRM_BusinessLayer.MM_Purchasing

 
Private Sub DeleteOldTrans()
        mobjCRMBAL = New CRM_BusinessLayer.MM_Purchasing(Session("SQLConStr").ToString, Session("SAPConStr").ToString)
        mobjCRMBAL.DeleteTrans(Session.SessionID)
    End Sub

请帮忙。

谢谢

推荐答案

嗨Jerzon，



欢迎来到MSDN论坛。



1.请查看此官方文档：我是否必须安装或引用某些内容？



是的，我认为你确实需要安装和引用程序集（xx.dll），其中存在CRM_BusinessLayer和MM_P的定义u


2.根据您的代码结构，我认为CRM_BusinessLayer是NameSapce的名称，MM_Purchasing是其中的一个类。



我重现与您相同的问题和错误消息。我通过向vb项目添加自定义MM_Purchasing.vb文件来解决此问题。结构应该是这样的：

Hi Jerzon,

Welcome to MSDN forum.

1. Please check this official document: Do I have to install or reference something?

Yes, I think you do need to install and reference the assembly(xx.dll) where exists the definition of CRM_BusinessLayer and MM_Purchasing.

2. According to the structure of your code, I would think the CRM_BusinessLayer is name of NameSapce and MM_Purchasing is a class within it.

I reproduce the same issue and error message like yours. And I resolve the issue by adding a custom MM_Purchasing.vb file into the vb project. The structure should be like:

'declaration
Namespace CRM_BusinessLayer
    Friend Class MM_Purchasing
        Private toString1 As String
        Private toString2 As String

        Public Sub New(toString1 As String, toString2 As String)
            Me.toString1 = toString1
            Me.toString2 = toString2
        End Sub

        Friend Sub DeleteTrans(sessionID As String)
            Throw New NotImplementedException()
        End Sub
    End Class
End Namespace

您需要的是添加对程序集的引用，其中定义了CRM_BusinessLayer命名空间和MM_Purchasing类。之后，该项目可以很好地建立。

What you need is to add reference to the assembly in which defines the CRM_BusinessLayer namespace and MM_Purchasing class. After that the project can build well.

希望以上所有有帮助。如果我的回复有帮助，请给我一个反馈！

Hope all above helps. And if my reply is helpful or not, please give me a feedback!

最好的问候
