一个将datagrid控件内容输出到excel文件的demo.

生成EXCEL文件

复制代码 代码如下:

public void setToExcel()

{

// Response.Clear();

// Response.Buffer= true;

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

if (eformsn.Text=="")

{

DataGrid1.Visible=false;

Label1.Text="要汇入EXCEL，请先输入申请单号!";

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=EOL_"+eformsn.Text+".xls");

Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");

//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";

dl.EnableViewState = false;

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

//this 表示输出本页，你也可以绑定datagrid,或其他支持obj.RenderControl()属性的控件

dl.RenderControl(oHtmlTextWriter);

//this.DataBind.RenderControl(oHtmlTextWriter);

Response.Write(oStringWriter.ToString());

Response.End();

}

}
