NPOI-WebForm_Excel导入与导出

本文面对的是第一次 接触NPOI的童鞋

不必为了一些琐碎的事情搞的心情烦躁

废话不多说先上 Demo 的全家福

接下来直接上代码

  public partial class _Default : System.Web.UI.Page
     {
         protected void Page_Load(object sender, EventArgs e)
         {
             if (IsPostBack)
             {
                 //导出Excel
                 ExportByWeb("ExportDemo.xlsx");
             }
             RepeaterTable.DataSource = GetDtTable();
             RepeaterTable.DataBind();
         }

         public static MemoryStream ExcelStream()
         {
             DataTable dtTable = GetDtTable();
             return ExcelHelper.ExportDT(dtTable, "HeaderText");

         }

         private static DataTable GetDtTable()
         {
             string path = HttpContext.Current.Request.MapPath("~/App_Data/excel2007.xlsx");
             //调用ZK的ExcelHelper
             DataTable dtTable = ExcelHelper.ImportExceltoDt(path);
             return dtTable;
         }

         public static void ExportByWeb(string strFileName)
         {
             HttpContext curContext = HttpContext.Current;

             // 设置编码和附件格式
             curContext.Response.ContentType = "application/vnd.ms-excel";
             curContext.Response.ContentEncoding = Encoding.UTF8;
             curContext.Response.Charset = "";
             curContext.Response.AppendHeader("Content-Disposition",
                 "attachment;filename=" + HttpUtility.UrlEncode(strFileName, Encoding.UTF8));

             curContext.Response.BinaryWrite(ExcelStream().GetBuffer());
             curContext.Response.End();
         }
     }

代码很简单，很容易看懂O(∩_∩)O~

前台绑定数据的代码

 <h2>
         欢迎使用 NPOI
     </h2>
     <asp:Repeater ID="RepeaterTable" runat="server">
         <HeaderTemplate>
             <table border="" cellpadding="" cellspacing="">
                 <tr>
                     <td>
                         ID
                     </td>
                     <td>
                         品牌
                     </td>
                     <td>
                         型号
                     </td>
                 </tr>
         </HeaderTemplate>
         <ItemTemplate>
             <tr>
                 <td>
                     <%# DataBinder.Eval(Container.DataItem,"ID") %>
                 </td>
                 <td>
                     <%# DataBinder.Eval(Container.DataItem,"品牌") %>
                 </td>
                 <td>
                     <%# DataBinder.Eval(Container.DataItem,"型号") %>
                 </td>
             </tr>
         </ItemTemplate>
         <FooterTemplate>
             </table>
         </FooterTemplate>
     </asp:Repeater>
     <p>
         <form action="/" method="post">
         <input type="submit" name="name" value="导出" />
         </form>
     </p>
