未声明Filename变量 [英] Filename variable not declared

问题描述

嗨！ 

观察下面的代码片段。最后一行显示"Filename = Dir（path）"    "文件名"以前没有声明过。是"文件名"吗？保留字？或者，是"使用此单个
最后一行声明和初始化文件名​​？谢谢！ -   John 

Observe the below snippet of code. The last line which says "Filename = Dir(path)"    "Filename" is not previously declared. Is "Filename" a reserved word? Or, is "Filename declared and initialized with this single last line? Thanks! -  John 

推荐答案

您好

如果想要使用'文件名'，您需要声明它。

If want to use 'Filename' you would need to declare it.

例如，Dim文件名为string = folderPath& " * .stp"

For example, Dim Filename as string = folderPath & "*.stp"

更好的是，也许  Dim Filename As String = IO.Path.Combine（folderPath，" * .stp"）会更好。

Better still, maybe  Dim Filename As String = IO.Path.Combine(folderPath, "*.stp") would be better.

你想要实现什么，因为我认为你可能走错了路。您是否要列出目录中的all.stp文件？

What are you trying to achieve, as I think you may be on the wrong track. Are you wanting to list all.stp files from a directory?
