xpdf可以在Powershell中接受变量作为路径参数吗？

Question

我收到错误：

.\pdftotext.exe : pdftotext version 4.00
At C:\Users\eakinsa\Desktop\Style Guide Report\styleGuideReport.ps1:62 char:88
+ ... Style Guide Report\Includes\bin32\"; .\pdftotext.exe $selectedFile })
+                                          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (pdftotext version 4.00:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

使用以下代码行：

$okButton.Add_Click({cd "C:\Users\eakinsa\Desktop\Style Guide Report\Includes\bin32\"; .\pdftotext.exe $selectedFile })

我怀疑这是一个错误，因为我正在运行的可执行文件不接受Powershell变量作为参数，但我不确定。如果是这种情况，是否有解决方法？

背景资料：

我正在编写一个接受用户输入的pdf文件位置的脚本（通过文件打开对话框），并将结果存储在一个变量中，希望将其用作xpdf＆＃39;的路径参数。 s pdftotext.exe。
