因此,在“发生错误时,GoTo执行一次”下出现了一些SO问题和Google结果,在几乎每种情况下,建议的解决方案都是添加Err.Clear或通过一些论坛Resume清除错误。VBA错误一次只能处理一次,因此需要清除。
正如您可能已经猜到的那样,实现了这些功能后,我遇到了这个问题,该问题On Error GoTo仅执行一次,我不知道为什么。
下面是我的循环。我确实没有在顶部放一些代码,因为其中有很多代码与它无关。通常是用户提示并创建数组。为了说明情况, conos()是一个包含特定列的值的数组。基于文件名的一部分,它在数组中搜索代码,以获取其索引,该索引与该行相对应。
如果没有,Match则会触发错误。那只是意味着有一个文件,但是没有联系人发送给它。它应该跳至NoContact并创建这些文件的列表。
因此,对于我的文件,第一个有一个联系人并生成电子邮件,第二个没有,而是跳转到NoContact该文件并将其添加到列表中。与联系人再运行五个,然后转到另一个应转到NoContact,但Unable to get the Match property of the WorksheetFunction class出现的联系人。
似乎该错误并未从第一个错误中消除。不知道为什么。

Err.Clear只是从Err对象中清除有关上一个错误的信息-它不会退出错误处理模式。
如果检测到错误并On Error GoTo NoContact调用了您,则您的代码将跳至NoContact标签,然后最终仍在错误处理模式下找到回到For Each objFile In objFolder.Files循环起点的代码。
如果仍在错误处理模式下发生另一个错误,则VBA将抛出错误,因为它不再能够捕获该错误。
您应该按照以下步骤构建代码
For Each objFile In objFolder.Files
'...
On Error GoTo NoContactError
'...
NoContact:
'...
Next
'...
Exit Sub
NoContactError:
'Error handling goes here if you want it
Resume NoContact
End Sub

但是,正如蒂姆·威廉姆斯(Tim Williams)所评论的-最好避免出现需要On Error尽可能进行错误处理的情况。
