Vba Excel在目录中循环继续搜索，不匹配项

当我在目录中循环查找特定文件夹中的文件与主文件的单元格/行之一之间的匹配，并将这些匹配的行复制到主文件时，如果主文件与我循环的文件夹中的文件之间不匹配，我会收到错误91通知

如果一个特定的文件没有匹配项，我希望我的宏自动查看下一个文件，依此类推，而不给我这个明显的错误。有什么建议可以解决这个问题吗

在if匹配条件之后使用此条件。它将在匹配条件之后执行，但请将其保留在循环中

if index = lastindex then 'if you have reached the end of the current file
'proceed to next file

其中index是当前文件中正在扫描的行/列的索引，lastindex是当前文件的lastindex，因此是当前文件的结尾

但是，这需要您知道扫描文件的最新索引。但您可以通过do while循环轻松完成此任务：

上述循环适用于行，但您可以轻松地将其用于列。

希望这有帮助

更改宏的以下部分解决了此问题：

Next CurrentShtRowRef
             If Not CopyRange Is Nothing Then
              CopyRange.Select

              CopyRange.Copy
              MasterSht.Cells(MasterWBShtLstRw + 1, 1).PasteSpecial xlPasteValues
             End If

对于任何人看你的问题，我们需要看一下代码。请提供代码谢谢你的回复，为我的马可找出了具体的问题并不是太难，也没有太大的不同。不过，谢谢你的建议。

Next CurrentShtRowRef
             If Not CopyRange Is Nothing Then
              CopyRange.Select

              CopyRange.Copy
              MasterSht.Cells(MasterWBShtLstRw + 1, 1).PasteSpecial xlPasteValues
             End If
