一個將datagrid控件內容輸出到excel文件的demo.
生成EXCEL文件#region 生成EXCEL文件
public void setToExcel()
{
// Response.Clear();
// Response.Buffer= true;
// Response.Charset="utf-8";
if (eformsn.Text=="")
{
DataGrid1.Visible=false;
Label1.Text="要匯入EXCEL，請先輸入申請單號!";
Label1.Visible=true;
}
else
{
dl.DataSource=DB("query", "select * from msi_eol_list_line where eformsn="+eformsn.Text+" order by eformsn").Tables[0].DefaultView;
dl.DataBind();
//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=EOL_"+eformsn.Text+".xls");
Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");
//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";
dl.EnableViewState = false;
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
//this 表示輸出本頁，你也可以綁定datagrid,或其他支持obj.RenderControl()屬性的控件
dl.RenderControl(oHtmlTextWriter);
//this.DataBind.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
}
}
