如何创建Excel工作表并将其添加到Excel InterOp中的多个工作簿

我一直在按照以下模式使用Excel InterOp创建多个工作表和多个工作簿 . 现在，我需要创建一个let调用一个主工作簿，它将包含我在原始工作簿中创建的工作表中的一些工作表 . 举一个例子，假设WorkBook1有Sheet1和Sheet2，而Workbook2有sheet3和sheet4 . 我希望Master工作簿有Sheet1和Sheet3 . 我正在寻找一种方法来创建我为WorkBook1和WorkBook2创建的工作表（sheet1，sheet2，sheet3，sheet4），但是只需要少量的代码重复，就可以将sheet1和sheet3添加到Master工作簿中 . 任何帮助将不胜感激 .

For i = 1 To 10
   Dim xlApp As Application = New Application
   Dim xlWorkBook As Workbook
   xlWorkBook = xlApp.Workbooks.Add
   Dim xlWorkSheet As Worksheet
   Dim xlSheets As Sheets = xlWorkBook.Sheets
   Dim xlNewSheet As Worksheet
   Dim sheetCount As Integer = 1

   ' So I repeat the following block to add multiple sheets with different content to a WorkBook
   xlNewSheet = xlSheets.Add(xlSheets(sheetCount), Type.Missing, Type.Missing, Type.Missing)
   sheetCount += 1
   xlNewSheet.Name = SomeName
   xlWorkSheet = xlWorkBook.Sheets(SomeName)
   AddContentToSheet(xlNewSheet) ' A Sub that adds real content to the sheet
   .
   .
   .
   .

   xlWorkBook.SaveAs(...)
   xlWorkBook.Close()
   xlApp.Quit()
Next i

所以现在，我的问题是，如果我有我的主工作簿：

Dim MasterWorkBook As Workbook
MasterWorkBook = xlApp.Workbooks.Add

在循环之前定义，重复10次以创建10个不同的WorkBook . 如何以最少的代码重复次数将选择的表格添加到MasterWorkBook .

    Dim xlApp As Application = New Application
    Dim masterWb As Workbook
    masterWb = xlApp.Workbooks.Add

    For i = 1 To 3
        Dim xlWorkBook As Workbook
        xlWorkBook = xlApp.Workbooks.Add
        Dim ws As Worksheet
        'Dim xlSheets As Sheets = xlWorkBook.Sheets
        'Dim xlNewSheet As Worksheet
        For j = 1 To 2
            Try
                ws = xlWorkBook.Sheets.Add(, xlWorkBook.Sheets(xlWorkBook.Sheets.Count))
                ws.Name = i + j
                AddContentToSheet(ws)
                If j = 1 Then
                    ws.Copy(, masterWb.Sheets(masterWb.Sheets.Count))
                End If
            Catch
                ws = Nothing
                xlWorkBook.Close()
                xlWorkBook = Nothing
                xlApp.Quit()
                xlApp = Nothing
                Console.WriteLine("error")
                Exit Sub
            End Try
        Next j

        'AddContentToSheet(xlNewSheet) ' A Sub that adds real content to the sheet
        ws = Nothing
        xlWorkBook.SaveAs("C:\Users\Documents\Visual Studio 2008\Project\" + Str(i) + ".xlsx")
        xlWorkBook.Close()
        xlWorkBook = Nothing
    Next i

    masterWb.Sheets("Sheet1").Delete()
    masterWb.Sheets("Sheet2").Delete()
    masterWb.Sheets("Sheet3").Delete()
    masterWb.SaveAs("C:\Users\Documents\Visual Studio 2008\Project\master.xlsx")
    masterWb.Close()
    masterWb = Nothing
    xlApp.Quit()
    xlApp = Nothing
End Sub

Sub AddContentToSheet(ByVal a As Worksheet)
    a.Cells(1, 1) = "abc"
    a.Cells(1, 2) = "abc"
End Sub

    该代码创建了3个工作簿，并在每个工作簿的末尾添加了2个工作表 . 它将第一个添加的工作表从每个工作簿复制到主工作簿 . 并记得在使用后释放对象引用 . 希望能帮助到你：）
