ASP.NET 在线下载Word,excel,txt文件，在线浏览html文件

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();
}
