1、在编辑代码前，需要在vs程序中引入Excel库。可直接通过Nuget搜索安装。可参考如下步骤：
2、程序中完成安装效果如图：
3、C#：using Spire.Xls;namespace ExcelToOFD{ class Program { static void Main(string[] args) { Workbook workbook = new Workbook(); workbook.LoadFromFile("test.xlsx"); workbook.SaveToFile("ToOFD.ofd", FileFormat.OFD); System.Diagnostics.Process.Start("ToOFD.ofd"); } }}
4、vb.net :Imports Spire.XlsNamespace ExcelToOFD Class Program Private Shared Sub Main(args As String()) Dim workbook As New Workbook() workbook.LoadFromFile("test.xlsx") workbook.SaveToFile("ToOFD.ofd", FileFormat.OFD) System.Diagnostics.Process.Start("ToOFD.ofd") End Sub End ClassEnd Namespace
