如何將數據綁到gridview然後導成excel

 這篇文章主要介紹了如何將數據綁到gridview然後導成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);// 創建數據庫連接實例    myConnection.Open(); //打開數據庫    SqlCommand myCommand = new SqlCommand(sql, myConnection);//創建sql的實例，執行一個sql      SqlDataAdapter Adapter = new SqlDataAdapter();//創建一個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 || 或其他浏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);  }  }
