本文实例讲述了ASP.NET使用GridView导出Excel实现方法。分享给大家供大家参考。具体实现方法如下:
/// <summary> /// 将DataTable数据导出到EXCEL,调用该方法后自动返回可下载的文件流 /// </summary> /// <param name="dtData">要导出的数据源</param> public static void DataTable1Excel(System.Data.DataTable dtData) { System.Web.UI.WebControls.GridView gvExport = null; // 当前对话 System.Web.HttpContext curContext = System.Web.HttpContext.Current; // IO用于导出并返回excel文件 System.IO.StringWriter strWriter = null; System.Web.UI.HtmlTextWriter htmlWriter = null; if (dtData != null) { // 设置编码和附件格式 curContext.Response.ContentType = "application/vnd.ms-excel"; curContext.Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312"); curContext.Response.Charset = "utf-8"; // 导出excel文件 strWriter = new System.IO.StringWriter(); htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter); // 为了解决gvData中可能进行了分页的情况,需要重新定义一个无分页的GridView gvExport = new System.Web.UI.WebControls.GridView(); gvExport.DataSource = dtData.DefaultView; gvExport.AllowPaging = false; gvExport.DataBind(); // 返回客户端 gvExport.RenderControl(htmlWriter); curContext.Response.Write("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=gb2312\" />" + strWriter.ToString()); curContext.Response.End(); } } /// <summary> /// 直接输出Excel /// </summary> /// <param name="dtData"></param> public static void DataTable2Excel(System.Data.DataTable dtData) { System.Web.UI.WebControls.DataGrid dgExport = null; // 当前对话 System.Web.HttpContext curContext = System.Web.HttpContext.Current; // IO用于导出并返回excel文件 System.IO.StringWriter strWriter = null; System.Web.UI.HtmlTextWriter htmlWriter = null; if (dtData != null) { // 设置编码和附件格式 curContext.Response.ContentType = "application/vnd.ms-excel"; curContext.Response.ContentEncoding =System.Text.Encoding.UTF8; curContext.Response.Charset = ""; // 导出excel文件 strWriter = new System.IO.StringWriter(); htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter); // 为了解决dgData中可能进行了分页的情况,需要重新定义一个无分页的DataGrid dgExport = new System.Web.UI.WebControls.DataGrid(); dgExport.DataSource = dtData.DefaultView; dgExport.AllowPaging = false; dgExport.DataBind(); // 返回客户端 dgExport.RenderControl(htmlWriter); curContext.Response.Write(strWriter.ToString()); curContext.Response.End(); } }
希望本文所述对大家的asp.net程序设计有所帮助。
