其实，利用ASP.NET输出指定内容的WORD、EXCEL、TXT、HTM等类型的文档很容易的。主要分为三步来完成。
一、定义文档类型、字符编码
Response.Clear(); Response.Buffer= true; Response.Charset="utf-8";
//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=FileFlow.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"; this.EnableViewState = false;
二、定义一个输入流
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
三、将目标数据绑定到输入流输出
this.RenderControl(oHtmlTextWriter);
//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
Response.Write(oStringWriter.ToString()); Response.End();
示例:
/// <summary> /// 导出数据到Excel表的方法 /// <param name="dt">DataTable数据源</param> /// <param name="title">生成的Excel文件名</param> /// </summary> public static void Export(System.Data.DataTable dt, string title) { StringWriter sw = new StringWriter();
foreach (System.Data.DataColumn col in dt.Columns) { sw.Write(col.Caption + "\t"); } sw.WriteLine();
foreach (System.Data.DataRow row in dt.Rows) { for (int i = 0; i < dt.Columns.Count; i++) { sw.Write(row[i].ToString() + "\t"); } sw.WriteLine(); }
sw.Close(); string filename = System.Web.HttpUtility.UrlPathEncode(title) + DateTime.Now.ToString("yyyyMMdd") + ".xls"; HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=" + filename); HttpContext.Current.Response.ContentType = "application/ms-excel"; HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); HttpContext.Current.Response.Write(sw); HttpContext.Current.Response.End(); }
