将工作表添加到 Excel 工作簿

我正在尝试创建一个WorkbookExcel 中有多个工作表，但我不知道如何创建多个工作表。我可以很好地创建一个，但是当我尝试创建第二个来写入时，我收到错误。

Dim app As Application = New Application
Dim xlApp As New Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim newXlApp As Excel.Application = New Microsoft.Office.Interop.Excel.Application
Dim newXlWorkbook As Excel.Workbook
Dim newXlSheet As Excel.Worksheet
Dim newXlSheet2 As Excel.Worksheet

Public Sub createWorkBook()
    newXlWorkbook = newXlApp.Workbooks.Add()

    newXlSheet = newXlWorkbook.Sheets("Sheet1")
    newXlSheet2 = newXlWorkbook.Sheets.Add("Sheet2")

    newXlSheet.Cells(1, 1) = "Task ID"
    newXlSheet.Cells(1, 2) = "Collective Tasks"
    newXlSheet.Cells(1, 3) = "Supported Task"

    newXlSheet2.Cells(1, 1) = "Parent Collective Task"
    newXlSheet2.Cells(1, 2) = "Individual Task"
End Sub

我不确定这是否重要，但我还有一个单独的 ExcelWorkbook打开我正在查询的内容。

据我所知，您的代码给出的错误将是：

“System.Runtime.InteropServices.COMException”类型的第一次机会异常

如果您想向 Excel 添加多个工作表Workbook这是执行此操作的代码：

Dim app As New Excel.Application
Dim wb As Excel.Workbook = app.Workbooks.Add()
Dim ws As Excel.Worksheet

ws = CType(wb.Sheets.Add(Count:=10), Excel.Worksheet)

默认情况下Workbook附带一个Sheet。如果您想添加多于一组Count:= parameter。正如你在我的例子中看到的，我使用了10。这将留给我 11 张工作表。

注意ws将是最后一张纸Workbook。在我的例子中，这将是Sheet11.

如果您想与每个人一起工作Worksheet那么你需要查看以下代码：

Dim ws1 As Excel.Worksheet = CType(wb.Sheets(1), Excel.Worksheet)
Dim ws2 As Excel.Worksheet = CType(wb.Sheets.Add(), Excel.Worksheet)

ws1.Cells(1, 1) = "Task ID"
ws1.Cells(1, 2) = "Collective Tasks"
ws1.Cells(1, 3) = "Supported Task"

ws2.Cells(1, 1) = "Parent Collective Task"
ws2.Cells(1, 2) = "Individual Task"

注意ws1参考第一张纸。正如上面所说的一个Workbook默认情况下附带一张。
