$Form.Controls.AddRange(@($ChooseML, $Prefix, $ChooseML_L, $Apply, $Cancel, $SelectML, $NB, $DPC))
[void] $Form.ShowDialog()

使用此代码，我可以转到任何文件夹.我希望我可以转到我需要的特定文件夹并选择文件.

With this code I can go to any folder. My expectation I can go to a specific folder that I need and choose the file.

这是有效的

Function Sel_File
 {
 $OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog
 $OpenFileDialog.InitialDirectory = "C:\Users\XX"
 $OpenFileDialog.Title = "Please Select File"
 $OpenFileDialog.filter = "All files (*.*)| *.*"
 If ($OpenFileDialog.ShowDialog() -eq "Cancel") 
 {
  [System.Windows.Forms.MessageBox]::Show("No File Selected. Please select a file !", "Error", 0, 
  [System.Windows.Forms.MessageBoxIcon]::Exclamation)
  }   $Global:SelectedFile = $OpenFileDialog.SafeFileName
    
}

推荐答案

如果你想保留最后一个文件夹，你可以这样做:

If you want keep the last folder you can do it:

 $OpenFileDialog.RestoreDirectory = $True

如果您只想指定初始目录，请像这样修改您的代码:

If you want just specify your initial directory modify your code like this:

Sel_File "c:\temp"
