Question

有人可以帮我解决如何在vb.net中打开excel表而不保存它吗？我想将DataGridView的数据导出到excel进行编辑，然后将其返回到DataGridView，在这种情况下，我不想将这个excel表保存到计算机，只是打开它进行编辑，然后在数据导入DataGridView后关闭

编辑 - 下面是dode

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles enter code hereButton2.Click

    Dim xlApp As Microsoft.Office.Interop.Excel.Application
    Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook
    Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
    Dim misValue As Object = System.Reflection.Missing.Value
    Dim i As Integer
    Dim j As Integer

    xlApp = New Microsoft.Office.Interop.Excel.Application
    xlWorkBook = xlApp.Workbooks.Add(misValue)
    xlWorkSheet = xlWorkBook.Sheets("Sheet1")


    For i = 0 To DataGridView1.RowCount - 2
        For j = 0 To DataGridView1.ColumnCount - 1
            For k As Integer = 1 To DataGridView1.Columns.Count
                xlWorkSheet.Cells(1, k) = DataGridView1.Columns(k - 1).HeaderText
                xlWorkSheet.Cells(i + 2, j + 1) = DataGridView1(j, i).Value
            Next
        Next
    Next

    Dim xlpath As String = Path.GetTempPath()

    xlWorkSheet.SaveAs(xlpath & "checkfile.xlsx")

    Process.Start(xlpath & "checkfile.xlsx")

Answer 1

您可以将文件保存在Path.GetTempPath文件夹中，然后使用Process.Start方法将其打开。

要在DataGridView中重新加载数据，您可以使用FileSystemWatcher课程。

打开microsoft excel表而不是保存到计算机
