Question

我能够使用Microsoft.Office.Interop.Excel.Worksheet在C＃/ VB.net中创建Excel工作表并将其添加到工作簿中，并最终如下所示打开Excel：

 Private Sub MainWindow_Loaded(sender As Object, e As RoutedEventArgs)
    Dim excel As Object = New Microsoft.Office.Interop.Excel.Application()
    Dim wb As Object = excel.Workbooks.Add()
    Dim wk1 As Object = CType(wb.Sheets.Add(), Microsoft.Office.Interop.Excel.Worksheet)
    Dim wk2 As Object = CType(wb.Sheets.Add(), Microsoft.Office.Interop.Excel.Worksheet)
    Dim wk3 As Object = CType(wb.Sheets.Add(), Microsoft.Office.Interop.Excel.Worksheet)

    wk3.Name = "Work Sheet Three"
    wk2.Name = "Work Sheet Two"
    wk1.Name = "Work Sheet One"

    OpenWorkSheetOne()
    OpenWorkSheetTwo()
    OpenWorkSheetThree()

    excel.Visible = True
    wb.Activate()

End Sub

C＃

 Private void MainWindow_Loaded(object sender, RoutedEventArgs e)
 { 
  object excel = new Microsoft.Office.Interop.Excel.Application();
  object wb = excel.Workbooks.Add();
  object wk1 = (Microsoft.Office.Interop.Excel.Worksheet)wb.Sheets.Add();
  object wk2 = (Microsoft.Office.Interop.Excel.Worksheet)wb.Sheets.Add();
  object wk3 = (Microsoft.Office.Interop.Excel.Worksheet)wb.Sheets.Add();
  wk3.Name = "Work Sheet Three";
  wk2.Name = "Work Sheet Two";
  wk1.Name = "Work Sheet One";

  OpenWorkSheetOne();
  OpenWorkSheetTwo();
  OpenWorkSheetThree();

  excel.Visible = true;
  wb.Activate();

   }

我有几个工作表，处理时间太长。我想（也许）在不同的线程上同时处理工作表（我想）并将它们同时添加到工作簿中。

我该怎么做并减少处理时间？

我已经用Google搜索，找不到合适的答案。

尝试使用此库：
https://github.com/ClosedXML/ClosedXML

使用非常简单：

using (var workbook = new XLWorkbook()){
var worksheet = workbook.Worksheets.Add("Sample Sheet");
worksheet.Cell("A1").Value = "Hello World!";
worksheet.Cell("A2").FormulaA1 = "=MID(A1, 7, 5)";
workbook.SaveAs("HelloWorld.xlsx");

}

同时创建多个excel工作表
