OpenXmlHelper，其于OpenXml SDK2.0写的帮助类，主要实现Excel的导出、导入的功能及具体的源码Demo
OpenXmlHelper代码如下：

导出Excel的代码如下：
/// <summary> /// 导出Excel /// </summary> /// <param name="filePath"> /// The file path. /// </param> /// <param name="fileTemplatePath"> /// The file template path. /// </param> /// <exception cref="Exception"> /// </exception> private void ExcelOut(string filePath, string fileTemplatePath) { try { System.IO.File.Copy(fileTemplatePath, filePath); } catch (Exception ex) { throw new Exception("复制Excel文件出错" + ex.Message); } using (SpreadsheetDocument document = SpreadsheetDocument.Open(filePath, true)) { var sheetData = document.GetFirstSheetData(); OpenXmlHelper.CellStyleIndex = 1; ////写标题相关信息 this.UpdateTitleText(sheetData); const string ENo = "C", EName = "D", EB = "E", EW = "F", DNo = "A", DName = "B", R = "G"; const int StartRowIndex = 4, Len = 10; for (var i = 0; i < Len; i++) { var rowIndex = StartRowIndex + i; // 员工信息 sheetData.SetCellValue(ENo + rowIndex, "Eno" + rowIndex); sheetData.SetCellValue(EB + rowIndex, DateTime.Now.AddYears(-30).AddYears(new Random().Next(1, 30))); sheetData.SetCellValue(EName + rowIndex, "员工姓名" + rowIndex); sheetData.SetCellValue(EW + rowIndex, "入职时间为：" + DateTime.Now.AddYears(-3).AddDays(new Random().Next(1, 1000))); // 部门信息 sheetData.SetCellValue(DNo + rowIndex, "DNo" + rowIndex); sheetData.SetCellValue(DName + rowIndex, "部门名称" + rowIndex); // 备注 sheetData.SetCellValue(R + rowIndex, "Remark:" + rowIndex); } // var str = OpenXmlHelper.ValidateDocument(document);验证生成的Excel } }
导出Excel的效果图：
