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); } }
