Question

现在标题可能会误解已经问过的问题，但我想根据我在vb.net中的代码找到一个具体的答案

Private Sub Button1_Click_1(sender As Object, e As EventArgs) Handles Button1.Click
Dim headers = (From header As DataGridViewColumn In DGVData.Columns.Cast(Of DataGridViewColumn)() _
          Select header.HeaderText).ToArray
        Dim rows = From row As DataGridViewRow In DGVData.Rows.Cast(Of DataGridViewRow)() _
                   Where Not row.IsNewRow _
                   Select Array.ConvertAll(row.Cells.Cast(Of DataGridViewCell).ToArray, Function(c) If(c.Value IsNot Nothing, c.Value.ToString, ""))

        Using sw As New IO.StreamWriter("csv.csv")
            sw.WriteLine(String.Join(",", headers))
            For Each r In rows
                sw.WriteLine(String.Join(",", r))
            Next
        End Using
        Process.Start("csv.csv")
    End If
End Sub

我的上一栏是格式为yyyy-mm-dd HH：mm：ss的日期，但是当导出到.csv时，日期格式不同，我需要更改以制作所述的日期格式？感谢您的时间和精力

Answer 1

在您写入Excel之前，请将列的格式设为文本。这应该纠正它

Cell.number.format =“@”

从datagridview导出到csv时更改日期格式
