原创文档-Winform开发框架提供通用导入Excel功能界面|C/S框架网

C# Code:

private void btnExcelImport_Click(object sender, EventArgs e)
{
   //导入产品三层结构Excel数据
   Import3LevelProductXLS target = new Import3LevelProductXLS();
   
   //打开通用导入界面
   frmImportExcel.ExecuteImporter(target, target.GetMapping());
   
   if (!String.IsNullOrWhiteSpace(target.ErrorInfo))
   {
      Msg.Warning(target.ErrorInfo);//导入失败提示

      //导入成功则刷新数据
      if (target.LastImportCounter > 0)
