c# – 将数据导出到Excel通过Open XML启用宏

此答案中的代码将复制任何Excel文件并将其切换到启用宏的工作簿.我已经针对一个简单的Excel 2016工作簿和宏启用工作簿对其进行了测试,它在源文件所在的同一目录中创建了一个新文件SaveMEW.xlsm.确保将源文件的完整路径放入`_sourceFile变量中.

var _sourceFile = " PATH TO YOUR TEMPLATE FILE ";

    using (var templateFile = File.Open(_sourceFile,FileMode.Open,FileAccess.Read))
        {
            using (var stream = new MemoryStream())
            {
                templateFile.CopyTo(stream);
                using (var spreadsheetDocument = SpreadsheetDocument.Open(stream,true))
                {                
                    spreadsheetDocument.ChangeDocumentType(SpreadsheetDocumentType.MacroEnabledWorkbook);
                }
                byte[] buffer = stream.ToArray();
                MemoryStream ms = new MemoryStream(buffer);
                FileStream file = new FileStream(System.IO.Path.GetDirectoryName(_sourceFile) + "/SaveMEW.xlsm",FileMode.Create,FileAccess.Write);
                ms.WriteTo(file);
                file.Close();
            }
        }
