我有这个字符串：
Process.exe /Switch=Value /Switch="C:\Path with spaces\file.txt" wrong argument
我想捕获这些部分：
· 1st Match: Process.exe · 2nd Match: /Switch=Value · 3rd Match: /Switch="C:\Path with spaces\file.txt" · 4th Match: wrong · 5th Match: argument
正则表达式需要用于通用（具有真实参数的过程），不仅适用于这种情况。
这就是我想要的：
Dim DebugArguments As String =
"HotkeyMaker.exe /Hotkey=Escape /run=""c:\folder with spaces\notepad.exe"""
For Each match As Match In Regex.Matches(DebugArguments, "([^\s]+[^""])")
MsgBox(match.Value)
Next match

修改
在这里，你去一个解析C / C ++命令行参数的正则表达式。每个论点都必须是
进一步子处理以解决参数级别上的转义和双引号。
此外，这不会解析特殊的管道/重定向符号，因为它首先由命令解释程序（cmd.exe）解析。相反，它将传递给语言的CreateProcess（）的字符串分开（解析）。这个是C / C ++，可能会有不同的解析，具体取决于命令调用的语言。

尝试这样的事情。
Dim DebugArguments As String =
"HotkeyMaker.exe /Hotkey=""Escape"" /run=""c:\folder with spaces\notepad.exe"""
Dim myMatches As MatchCollection
Dim MyRegEx As New Regex("([^\/]+""|[^/\s]+)")
myMatches = MyRegEx.Matches(DebugArguments)
For Each match In myMatches
MsgBox(match.Value)
Next
