使用 VB.Net 将 Excel 转换为 HTML

Question

在 Windows 窗体中，我需要将数据（A 列到 C 列）从 Excel 导出到 HTML。我正在尝试如下，但在namedRanges中得到“未找到类型‘工作表’上的公共成员‘NamedaRanges’”。之后无法验证是否会成功保存 HTML。请帮忙解决这个问题。Private Sub Button_click()     xlSheet=xlWB.Worksheets("Sheet3")      xlSheet.NamedRanges.SetPrintArea          (xlSheet.Cells.GetSubrange                          ("A1",C1"))    xlSheet.SaveAs(FileName:="C:\Users\      Sample.html",FileFormat:=xlHtml)End Sub

对于非连续范围，您可能必须将其作为连续范围复制到临时工作表并将其导出

Private Sub Button6_Click(sender As Object, e As EventArgs) Handles Button6.Click

        Const folder = "C:\tmp\"

        Const xlFile = "test1.xlsx"

        Const htmlfile = "export.html"

        Dim xls As New Excel.Application

        Dim wb As Workbook

        Dim ws As Worksheet, wsHtml As Worksheet

        wb = xls.Workbooks.Open(folder & xlFile, False, True) ' no link update , radonly

        ws = wb.Worksheets("Sheet3")

        ' create temp sheet, copy range to it, export and then delete it

        wsHtml = wb.Sheets.Add()

        ws.Range("A:A,C:C").Copy(wsHtml.Range("A1"))

        wsHtml.PageSetup.PrintArea = wsHtml.Columns("A:B").Address

        wsHtml.SaveAs(Filename:=folder & htmlfile, FileFormat:=44) ' html

        xls.DisplayAlerts = False

        wsHtml.Delete()

        xls.DisplayAlerts = True

        wb.Close(False)

        xls.Quit()

        MsgBox("Exported to " & folder & htmlfile)

    End Sub
