Question

我试图让我的应用程序无法关闭，直到特定目录中的所有文件都有一定的前缀。我的主目录中有5个子目录，但是我必须让它只搜索3个特定的子目录吗？我希望应用程序无法关闭，除非这3个子目录中的所有文件都具有前缀...

这是我到目前为止的代码

 Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing

e.Cancel = True

    Dim directory As New IO.DirectoryInfo(dir)

    For Each file In directory.EnumerateFiles("*.txt", IO.SearchOption.TopDirectoryOnly)

        If file.Name.Contains("prefix.") Then
            e.Cancel = False
        Else e.Cancel = True

        End If


    Next

如果你只需要搜索5个子目录中的3个，我假设他们的名字/路径是静态的。如果是这样，这将有效。

Dim directoriesToSearch() As String = {"C:\TopDirectory\SubDir1", "C:\TopDirectory\SubDir2", "C:\TopDirectory\SubDir3"}
Dim sb As New StringBuilder()

For Each d In directoriesToSearch
  Dim directory As New IO.DirectoryInfo(d)

  For Each f As FileInfo In directory.EnumerateFiles()
    If f.Name.IndexOf("myPrefix") <> 0 Then
      Dim message As String = String.Format("The directory {0} does not have the valid prefix.", d)
      sb.AppendLine(message)
    End If
  Next
Next

If sb.Length > 0 Then
  MessageBox.Show(sb.ToString)
End If

是否可以搜索目录中的特定目录？
