本文實(shí)例講述了C#導(dǎo)出GridView數(shù)據(jù)到Excel文件類(lèi)。分享給大家供大家參考。具體如下：
這段C#代碼自定義了一個(gè)封裝類(lèi)，用于將GridView數(shù)據(jù)導(dǎo)出到Excel文件
using System;using System.Web;using System.Web.UI;using System.IO;using System.Web.UI.WebControls;namespace DotNet.Utilities{ public class ExportExcel { protected void ExportData(string strContent, string FileName) { FileName = FileName + DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + DateTime.Now.Millisecond.ToString(); HttpContext.Current.Response.Clear(); HttpContext.Current.Response.Charset = "gb2312"; HttpContext.Current.Response.ContentType = "application/ms-excel"; HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8; //this.Page.EnableViewState = false; // 添加頭信息，為"文件下載/另存為"對(duì)話框指定默認(rèn)文件名 HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ".xls"); // 把文件流發(fā)送到客戶(hù)端 HttpContext.Current.Response.Write("<html><head><meta http-equiv=Content-Type content=/"text/html; charset=utf-8/">"); HttpContext.Current.Response.Write(strContent); HttpContext.Current.Response.Write("</body></html>"); // 停止頁(yè)面的執(zhí)行 //Response.End(); } /// <summary> /// 導(dǎo)出Excel /// </summary> /// <param name="obj"></param> public void ExportData(GridView obj) { try { string style = ""; if (obj.Rows.Count > 0) { style = @"<style> .text { mso-number-format:/@; } </script> "; } else { style = "no data."; } HttpContext.Current.Response.ClearContent(); DateTime dt = DateTime.Now; string filename = dt.Year.ToString() + dt.Month.ToString() + dt.Day.ToString() + dt.Hour.ToString() + dt.Minute.ToString() + dt.Second.ToString(); HttpContext.Current.Response.AddHeader("content-disposition", "attachment; filename=ExportData" + filename + ".xls"); HttpContext.Current.Response.ContentType = "application/ms-excel"; HttpContext.Current.Response.Charset = "GB2312"; HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); obj.RenderControl(htw); HttpContext.Current.Response.Write(style); HttpContext.Current.Response.Write(sw.ToString()); HttpContext.Current.Response.End(); } catch { } } }}希望本文所述對(duì)大家的C#程序設(shè)計(jì)有所幫助。
