 这篇文章主要介绍了如何将数据绑到gridview然后导成excel,需要的朋友可以参考下

 代码如下: using System;  using System.Collections.Generic;  using System.Linq;  using System.Web;  using System.Web.UI;  using System.Web.UI.WebControls;  using System.Data .SqlClient ;  using System.Data ;    public partial class _Default : System.Web.UI.Page  {  protected void Page_Load(object sender, EventArgs e)  {  String sqlconn = "Server=.; DataBase=db; Integrated Security=SSPI ";  string sql = "select top 10 * from table";    SqlConnection myConnection = new SqlConnection(sqlconn);// 创建数据库连接实例    myConnection.Open(); //打开数据库    SqlCommand myCommand = new SqlCommand(sql, myConnection);//创建sql的实例,执行一个sql      SqlDataAdapter Adapter = new SqlDataAdapter();//创建一个sql数据适配器  Adapter.SelectCommand = myCommand;//属性设置为 从数据源中检索记录      DataSet myDs = new DataSet(); //创建数据集实例  Adapter.Fill(myDs);//填充数据集    GridView1.DataSource = myDs.Tables[0].DefaultView;//  GridView1.DataBind();    // DataToExcel("测试的cxcel", GridView1);  myConnection.Close();//关闭数据库连接  }  public void DataToExcel(string fileName, GridView myGridView)  {  //定义文档类型、字符编码  Response.Clear();  Response.Buffer = false;  //Response.Charset = "utf-8";  Response.Charset = "GB2312";  //下面这行很重要, attachment 参数表示作为附件下载,您可以改成 online在线打开  //filename=FileFlow.xls 指定输出文件的名称,注意其扩展名和指定文件类型相符,可以为:.doc || .xls || .txt ||.htm  Response.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8) + ".xls");  Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");  //Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");  //Response.ContentType指定文件类型 可以为application/ms-excel || application/ms-word || application/ms-txt || application/ms-html || 或其他浏览器可直接支持文档  Response.ContentType = "application/ms-excel";  this.EnableViewState = false;  //System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);  //定义一个输入流  System.IO.StringWriter oStringWriter = new System.IO.StringWriter();  System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);  //将目标数据绑定到输入流输出  myGridView.RenderControl(oHtmlTextWriter);  Response.Write(oStringWriter.ToString());  Response.End();  }    //下面这个空语句一定要加,否则会出现“必须放在具有 runat=server 的窗体标记内。”的错误  public override void VerifyRenderingInServerForm(Control control)  {  }    //点击事件,生成excel  protected void Button1_Click(object sender, EventArgs e)  {  DataToExcel("测试的cxcel", GridView1);  }  }
