我们可以使用epplus库创build带有checkbox选项的下拉列表

初始化工作表：

public HttpResponseMessage ER_GenerateWBLWorksheet2() { ExcelPackage ExclPkg = new ExcelPackage(); ExcelWorksheet wsSheet1 = ExclPkg.Workbook.Worksheets.Add("Sheet1"); wsSheet1.Cells["A1"].Value = "ProductName"; wsSheet1.Cells["B1"].Value = "Price"; wsSheet1.Cells["C1"].Value = "ProductImageUrl"; wsSheet1.Cells["D1"].Value = "ProductUrl"; wsSheet1.Cells["E1"].Value = "StoreId"; wsSheet1.Cells["G1"].Value = "CategoryId"; wsSheet1.Cells["I1"].Value = "ColorId"; wsSheet1.Cells["K1"].Value = "FabricId"; wsSheet1.Cells["M1"].Value = "Gender"; 

创build类别列表：

 var categorylist = wsSheet1.DataValidations.AddListValidation(wsSheet1.Cells["G2:G500"].Address); var categories = _categoryServices.GetAllCategory(); var categoryEntities = (categories != null) ? categories.ToList() : new List<CategoryEntity>(); for (int i = 0; i < categoryEntities.Count; i++) { categorylist.Formula.Values.Add(categoryEntities[i].CategoryName.ToString()); } categorylist.ShowErrorMessage = true; categorylist.ErrorTitle = "Error"; categorylist.Error = "Please select the Category from Dropdown"; wsSheet1.Cells["G2:G500"].Style.Locked = false; 

创build颜色列表：

  var colorlist = wsSheet1.DataValidations.AddListValidation(wsSheet1.Cells["I2:I500"].Address); var colors = _colorServices.GetAllColor(); var colorsEntities = (colors != null) ? colors.ToList() : new List<ColorEntity>(); for (int i = 0; i < colorsEntities.Count; i++) { colorlist.Formula.Values.Add(colorsEntities[i].ColorName.ToString()); } colorlist.ShowErrorMessage = true; colorlist.ErrorTitle = "Error"; colorlist.Error = "Please select the Color from Dropdown"; wsSheet1.Cells["I2:I500"].Style.Locked = false; wsSheet1.Cells[wsSheet1.Dimension.Address].AutoFitColumns(); var filename = @"Inventory_" + DateTime.Now.ToString("M_dd_yyyy_H_M_s") + ".xlsx"; //string sPath = @"e:\" + filename; var sPath = System.Web.Hosting.HostingEnvironment.MapPath("~/exportedfiles/" + filename); Stream stream = File.Create(sPath); ExclPkg.SaveAs(stream); stream.Close(); string strServerPath = Convert.ToString(System.Configuration.ConfigurationManager.AppSettings["excelserverpath"]); var sPathURL = (strServerPath + "exportedfiles/" + filename); List<fileinfo> filelst = new List<fileinfo>(); fileinfo file = new fileinfo(); file.filename = filename; file.fileurl = sPathURL; //file.fileurl = sPath; filelst.Add(file); return new ResponseWrapper<fileinfo>(filelst, HttpStatusCode.OK, null, 0); } 

使用上面的代码，我创build了Excel的下拉列表，但我的要求是从下拉列表中select多个值。 是否有可能使用epplus库？
