Question

让我说我有一个shell

"chdir * && whoami.exe >> $$$"

我有这个替换命令

Dim ReplaceCommand as String = sCommand.Replace("*", UserDirect)

我也希望用用户选择的文件路径替换$$$。我可以选择文件路径，但它永远不会将它放入shell中。

我试过了

Dim ReplaceCommand1, ReplaceCommand2 as String = sCommand.Replace("*" & "$$$", UserDirect & filepath)
Shell("cmd.exe" & ReplaceCommand1 & ReplaceCommand2)

Dim ReplaceCommand as String = sCommand.Replace("*", UserDirect) & ("$$$", filepath)
Shell("cmd.exe" & ReplaceCommand)

也

Dim ReplaceCommand1 as String = sCommand.Replace("*", UserDirect)
Dim ReplaceCommand2 as String = sCommand.Replace("$$$", filepath)
Shell("cmd.exe" & ReplaceCommand1 & ReplaceCommand2)

编辑：当我在shell而不是＆amp;

中使用逗号时，获得一条错误路径

Dim ReplaceCommand1 as String = sCommand.Replace("*", UserDirect)
Dim ReplaceCommand2 as String = sCommand.Replace("$$$", filepath)
Shell("cmd.exe", ReplaceCommand1 , ReplaceCommand2)

Answer 1

您的部分示例未编译语法错误的原因。

你没有像你想的那样使用Shell（）。

Public Function Shell(
    PathName As String,
    Optional Style As Microsoft.VisualBasic.AppWinStyle = MinimizedFocus,
    Optional Wait As Boolean = False,
    Optional Timeout As Integer = -1
) As Integer

从您给出的示例中，看起来您只是把东西放在一起。停下来思考一下：）

Answer 2

您可以将替换链接在一起：

Dim ReplaceCommand1 as String = sCommand.Replace("*", UserDirect).Replace("$$$", filepath)
Shell("cmd.exe" & ReplaceCommand1)

多个替换命令的格式
