Question

此程序从今天已修改的文件夹中提取文件，在将文件放入另一个文件夹后，批处理文件将删除该源文件夹中的其余未修改文件。

我的程序应该做的最后一件事是从单独的文件夹中复制文件，然后将它们放回到该源文件夹中。

但我的程序只提取修改过的文件，删除该文件夹中的其余文件，但是当我运行程序同时复制并将新文件放入源文件夹时，它就不会这样做。有谁知道为什么？

Imports System.IO

Public Class frmExtractionator

    '  Dim txtFiles1 As Control
    Dim sourceDirectory As String = "F:\CopierFolderforTestDriveCapstone"
    Dim archiveDirectory As String = "F:\FilesExtracted"
    Dim originalDirectory As String = "F:\OriginalTestFiles"

    Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click

        Try

            Dim txtFiles = Directory.EnumerateFiles(sourceDirectory)

            If (Not System.IO.Directory.Exists(archiveDirectory)) Then
                System.IO.Directory.CreateDirectory(archiveDirectory)
            End If


            For Each currentFileLoc As String In txtFiles

                Dim fileName = currentFileLoc.Substring(sourceDirectory.Length + 1)



                If (IO.File.GetLastWriteTime(currentFileLoc).ToString("MM/dd/yyyy") = DateTime.Now.ToString("MM/dd/yyyy")) Then
                    MessageBox.Show(currentFileLoc & " moved", "Moved Succesfully")
                    File.Move(currentFileLoc, Path.Combine(archiveDirectory, fileName))

                End If

            Next
        Catch eT As Exception
            Console.WriteLine(eT.Message)
        End Try

        System.Diagnostics.Process.Start("F:\poop.bat")


        Try
            Dim txtFiles2 = Directory.EnumerateFiles(originalDirectory)

            For Each currentFileLoc2 As String In txtFiles2

                Dim fileName = currentFileLoc2.Substring(originalDirectory.Length + 1)

                File.Move(currentFileLoc2, Path.Combine(sourceDirectory, fileName))

            Next
        Catch eT As Exception
            Console.WriteLine(eT.Message)
        End Try
    End Sub

End Class

Answer 1

更改

Dim fileName = currentFileLoc2.Substring(originalDirectory.Length + 1)

到

Dim FileName = IO.Path.GetFileName(currentFileLoc2)

将文件复制回特定文件夹
