Question

因此，经过大量研究和使用下面的代码后，我传递的项目（一个DataTable）在Excel中打开。我有大约5张需要在同一本书中打开的纸张。下面的代码是第一个2.问题是它们都在NEW WorkBook中打开 - 我需要它们全部在SAME WorkBook中打开。但是，它们会在每个新工作簿的正确工作表上打开。我认为一个简单的“if”语句可行，但是，它不是 - 关于如何将它们整合到一个WorkBook中的任何输入都将非常感谢并提前感谢！

你的代码有点太长而无法在没有评论的情况下理解，但是如果你想在当前工作簿中添加一个新工作表，那么就有myWorkbook.Sheets.Add（）方法（其中myWorkbook是你当前工作簿的参考书））。

将Excel.WorkSheets转换为相同的Excel.Workbook
