私が試したこと：
VB
Using sw As New StreamWriter(OutPutFile) <pre> For I As Integer = 0 To dt.Rows.Count - 1 sw.WriteLine("------------------------------------------------------------") sw.WriteLine(dt.Rows(I).Item(0).ToString.PadRight(15) & vbTab & dt.Rows(I).Item(1).ToString().PadRight(25) & vbTab & dt.Rows(I).Item(2).ToString().PadRight(10) & vbTab & dt.Rows(I).Item(3).ToString()) Next Process.Start(OutPutFile)
使用終了
解決策 1
出力ファイルを使用する前にストリームを閉じてください。そうしないと、どの p でも開くことができません。[rocess – including ones in your own application.
In other words, the End Using needs to be before the Process.Start
