将工作表添加到Excel工作簿 [英] Adding a Sheet to an Excel Workbook

问题描述

我正在尝试在Excel中创建具有多个工作表的Workbook，但是我不知道如何创建多个工作表.我可以创建一个就好了，但是当我尝试创建第二个要写的文件时，却出现了错误.

I'm trying to create a Workbook with multiple sheets in Excel but I can't figure out how to create the multiple sheets. I can create one just fine, but when I try to create a second one to write to I get an error.

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，但我还有一个要查询的单独的Excel Workbook打开.

I'm not sure if it matters or not, but I also have a separate Excel Workbook open that I'm querying.

推荐答案

从我可以看到您的代码给出的错误将是:

From what I can see the error your code is giving will be:

类型为'System.Runtime.InteropServices.COMException'的第一次机会异常

A first chance exception of type 'System.Runtime.InteropServices.COMException'

如果要将多个工作表添加到Excel Workbook，请执行以下操作:

If you want to add multiple Sheets to your Excel Workbook this is the code to do that:

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带有一个Sheet.如果要添加多个，请设置Count:= parameter.如您在我的示例中看到的，我使用了 10 .这将给我11张工作表.

By default a Workbook comes with one Sheet. If you want to add more than one set the Count:= parameter. As you can see in my example I have used 10. This will leave me with 11 Sheets to work with.

请注意，ws将是Workbook中的最后一张纸.在我的示例中，该名称为 Sheet11 .

Note that ws will be the last sheet in the Workbook. In my example this would be Sheet11.

如果要使用每个Worksheet，则需要查看以下代码:

If you want to work with each Worksheet then you would need to look at the following code:

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"

请注意，ws1是指第一张纸.如上所述，默认情况下，Workbook随附一张纸.

Note that ws1 references to the first sheet. As said above a Workbook by default comes with one sheet.
