最近项目结束了，其中用到了Ext.Net的GridPanel导出Excel，简单的过程如下：
导出按钮的事件：
1 protected void btnExport_DirectClick(object sender, DirectEventArgs e)
2 {
3 if (Session["BorrowRecord"] != null)
4 {
5 DataTable tbBorrowRecord = (DataTable)Session["BorrowRecord"];
6 if (tbBorrowRecord.Rows.Count > 0)
7 {
8 string content = m_BorrowBLL.GetExportHtml(tbBorrowRecord); // 把DataTable表格转成HTML
9 string title = "工具借用记录导出" + DateTime.Now.ToString("yyyyMMddHHmmss");
10 Session["Content"] = content;
11 UIHelper.LogInfo("导出超修记录Exce", OperatorType.导出);
12 X.Redirect("/Ashx/LoadExcel.ashx?title=" + title);
13 }
14 else
15 {
16 // 没有数据，提示没有数据无法导出
17 Notification.Show(
18 new NotificationConfig
19 {
20 Title = "提示",
21 Icon = Icon.Information,
22 Html = "没有数据，无法导出！"
23 });
24 }
25 }
26 }
根据DataTable拼凑出Html table结构：
1 /// <summary>
2 /// 根据借用记录数据表格获取导出的HTML
3 /// </summary>
4 /// <param name="tbBorrowRecord"></param>
5 /// <returns></returns>
6 public string GetExportHtml(DataTable tbBorrowRecord)
7 {
8 tbBorrowRecord = tbBorrowRecord.DefaultView.ToTable(false, new string[] { "SectionName", "Category", "Model", "Code", "BorrowMan", "BorrowTime", "ReturnMan", "ReturnTime", "State" });
9 string html = string.Empty;
10 string datarow = string.Empty;
11 foreach (DataRow drBorrow in tbBorrowRecord.Rows)
12 {
13 string content = string.Empty; // 数据内容
14 datarow += "<tr>";
15 for (int i = 0; i < tbBorrowRecord.Columns.Count; i++)
16 {
17 if (tbBorrowRecord.Columns[i].ColumnName == "State")
18 {
19 switch (drBorrow[i].ToString())
20 {
21 case "1":
22 content = "未归还";
23 break;
24 case "2":
25 content = "已归还";
26 break;
27 }
28 }
29 else
30 {
31 content = drBorrow[i].ToString();
32
33 }
34 datarow += "<td>" + content + "</td>";
35 }
36 datarow += "</tr>";
37 }
38 html = string.Format(@"<html>
39 <meta http-equiv=‘Content-Type‘ content=‘text/html;charset=‘utf-8‘ />
40 <head></head>
41 <body>
42 <table style=‘border-collapse:collapse‘ bordercolor=‘#111111‘ cellSpacing=‘0‘ cellPadding=‘2‘ border=‘1‘>
43 <thead>
44 <th>工区</th>
45 <th>工具类型</th>
46 <th>规格型号</th>
47 <th>条形码</th>
48 <th>借用人</th>
49 <th>借用日期</th>
50 <th>归还人</th>
51 <th>归还日期</th>
52 <th>状态</th>
53 </thead>
54 {0}
55 </table>
56 </body>
57 </html>", datarow);
58
59 return html;
60 }
在一般处理程序中导出Excel
1 using System.Web;
2
3 namespace HuaweiSoftware.EMMS_JCW.UI.Ashx
4 {
5 /// <summary>
6 /// 导出记录到Excel
7 /// </summary>
8 public class LoadExcel : IHttpHandler, System.Web.SessionState.IRequiresSessionState
9 {
10 public void ProcessRequest(HttpContext context)
11 {
12 string content = context.Session["content"].ToString();
13 string title = context.Request["title"];
14 context.Session.Remove("content");
15
16 // 设置http流格式，写入拼接Excel内容
17 context.Response.Clear();
18 context.Response.Buffer = true;
19 context.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(title) + ".xls");
20 context.Response.ContentEncoding = System.Text.Encoding.UTF8;
21 context.Response.ContentType = "application/vnd.ms-excel";
22 context.Response.Write(content);
23 context.Response.End();
24 }
25
26 public bool IsReusable
27 {
28 get
29 {
30 return false;
31 }
32 }
33 }
34 }
