所以我正在尝试将用户放入ListBox的文件复制,我似乎遇到了问题,因为在我尝试复制文件的行上,我收到了这个错误:
An unhandled exception of type 'System.NotSupportedException' occurred in mscorlib.dll Additional information: The given path's format is not supported.
经过一番研究后,我认为这是因为我合并了字符串和东西,但我不确定所以我想我也可以问这里。
如果有帮助,我确认列表框项目是有效的文件路径。
这是我的代码:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim result As DialogResult = MessageBox.Show("Are you sure you want to finish the playlist?", "Finish Playlist- WikiFinder", MessageBoxButtons.YesNo)
If (result = DialogResult.Yes) Then
For Each Item In ListBox1.Items
My.Computer.FileSystem.CopyFile(Item.ToString(), MusicMenu.FolderBrowserDialog2.SelectedPath.ToString() & Item.ToString())
Next
Else
End If
End Sub
请记住,我从未真正使用过listboxes,这是我第一次尝试使用CopyFile方法。有人能帮助我吗?

Path.Combine方法解决了我的问题。
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim result As DialogResult = MessageBox.Show("Are you sure you want to finish the playlist?", "Finish Playlist- WikiFinder", MessageBoxButtons.YesNo)
If (result = DialogResult.Yes) Then
For Each Item In ListBox1.Items
Dim str As String = IO.Path.Combine(MusicMenu.FolderBrowserDialog2.SelectedPath.ToString(), Item.ToString())
My.Computer.FileSystem.CopyFile(Item.ToString(), str)
Next
Else
End If
End Sub
我相信当你写下路径时你不能合并字符串,这就是我做错了。
