這篇文章主要介紹了如何將數據綁到gridview然后導成excel,需要的朋友可以參考下

代碼如下:

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);// 創(chuàng)建數據庫連接實例

myConnection.Open(); //打開數據庫

SqlCommand myCommand = new SqlCommand(sql, myConnection);//創(chuàng)建sql的實例，執(zhí)行一個sql

SqlDataAdapter Adapter = new SqlDataAdapter();//創(chuàng)建一個sql數據適配器

Adapter.SelectCommand = myCommand;//屬性設置為 從數據源中檢索記錄

DataSet myDs = new DataSet(); //創(chuàng)建數據集實例

Adapter.Fill(myDs);//填充數據集

GridView1.DataSource = myDs.Tables[0].DefaultView;//

GridView1.DataBind();

// DataToExcel("測試的cxcel", GridView1);

myConnection.Close();//關閉數據庫連接

}

public void DataToExcel(string fileName, GridView myGridView)

{

//定義文檔類型、字符編碼

Response.Clear();

Response.Buffer = false;

//Response.Charset = "utf-8";

Response.Charset = "GB2312";

//下面這行很重要， attachment 參數表示作為附件下載，您可以改成 online在線打開

//filename=FileFlow.xls 指定輸出文件的名稱，注意其擴展名和指定文件類型相符，可以為：.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指定文件類型 可以為application/ms-excel || application/ms-word || application/ms-txt || application/ms-html || 或其他瀏覽器可直接支持文檔

Response.ContentType = "application/ms-excel";

this.EnableViewState = false;

//System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);

//定義一個輸入流

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

//將目標數據綁定到輸入流輸出

myGridView.RenderControl(oHtmlTextWriter);

Response.Write(oStringWriter.ToString());

Response.End();

}

//下面這個空語句一定要加，否則會出現“必須放在具有 runat=server 的窗體標記內。”的錯誤

public override void VerifyRenderingInServerForm(Control control)

{

}

//點擊事件，生成excel

protected void Button1_Click(object sender, EventArgs e)

{

DataToExcel("測試的cxcel", GridView1);

}

}
