1 引用的命名空间

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

2 处理不同类型的文件

    private void ShowPDF()
    {
        Response.ContentType = "Application/pdf";
        string filePath = MapPath("Acrobat.pdf");
        Response.WriteFile(filePath);
        Response.End();
    }
    private void ShowWord()
    {
        Response.ContentType = "Application/msword";
        string filePath = MapPath("Temp.doc");
        Response.WriteFile(filePath);
        Response.End();
    }

    private void ShowExcel()
    {
        Response.ContentType = "Application/x-msexcel";
        string filePath = MapPath("最新通讯录(2008.12月版).xls");
        Response.WriteFile(filePath);
        Response.End();
    }

    private void ShowHtml()
    {
        Response.ContentType = "text/HTML";
        string filePath = MapPath("GlideView.html");
        Response.WriteFile(filePath);
        Response.End();
    }

3 以上方法2也可以用以下方法来处理，方法3的灵活性更高

  protected void btnOpenWord_Click(object sender, EventArgs e)
    {
      //  string tmpFileName = "C:\\Users\\hardenchen\\Desktop\\jyzx_20091229180011-0.doc";
        string tmpFileName = "C:\\Users\\hardenchen\\Desktop\\GlideView.html";
        FileInfo tmpFI = new FileInfo(tmpFileName);
        Response.Clear();
        Response.ClearHeaders();
        Response.Buffer = false;

        Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(Path.GetFileName(tmpFileName), System.Text.Encoding.UTF8));
        Response.AppendHeader("Content-Length", tmpFI.Length.ToString());
        Response.ContentType = "application/octet-stream";
        Response.WriteFile(tmpFileName);
        Response.Flush();
        Response.End();
    }
