我正在创建一个应用程序,它涉及读取现有文件的块并将它们写入一个新文件...现在,问题是我当前使用的代码不会创建子文件夹然后提交文件,如果完整路径是给定...
如果我给它一个这样的路径:C:\ folder1 \ folder2 \ file.mp3它给出一个错误,因为文件夹folder1和2不存在,但是,我希望它创建这些子文件夹,如果他们不在创建文件时存在...谢谢......这是我的代码:
Dim bytesRead As Integer
Dim buffer(40096) As Byte
Using inFile As New System.IO.FileStream(arch, IO.FileMode.Open, IO.FileAccess.Read)
Using outFile As New System.IO.FileStream(path & "\" & f, IO.FileMode.Create, IO.FileAccess.Write)
inFile.Seek(StartAt, IO.SeekOrigin.Begin)
Do
If astop.Text = 1 = False Then
If CurrentFsize - currtotal < buffer.Length Then
ReDim buffer(CurrentFsize - currtotal)
End If
bytesRead = inFile.Read(buffer, 0, buffer.Length)
If bytesRead > 0 Then
outFile.Write(buffer, 0, bytesRead)
currtotal += bytesRead
End If
Else
Exit Do
Exit Do
End If
Application.DoEvents()
Loop While bytesRead > 0 AndAlso currtotal < CurrentFsize
End Using
End Using
答案 0 :(得分:2)
Yout应该在创建输出文件之前创建path
的目录和子目录:
If(Not System.IO.Directory.Exists(path)) Then
System.IO.Directory.CreateDirectory(path)
