無法將類型為system.string的對象轉換為類型為system.io.fileinfo的對象

Question

您好，我正在嘗試使用列表框內的路徑，但出現錯誤

Dim items As New ListBox

'Getting the path of the selected file on opendialog'
For Each filename As String In OpenFileDialog1.FileNames
    items.Items.Add(filename)
Next

For Each sourcepath As FileInfo In items.Items()
    sourcepath.CopyTo(path)
Next

Answer 1

您已經在列表框中放置了字符串，因此當您循環這些項目時，您將獲得字符串。 如果要使用FileInfo對象，則必須從字符串創建它們：

For Each sourcepath As String In items.Items
    Dim fileInfo = New FileInfo(sourcepath).CopyTo(path)
Next
