程序实现下载文件或者打开文件

FileInfo DownloadFile = new FileInfo("c:\\a.doc");

// 下面到就是读取文件，通过数据流的方式下载了。

Response.Clear();

Response.ClearHeaders();

Response.Buffer = false;

Response.ContentType = "application/octet-stream";

Response.AppendHeader("Content-Disposition", "inline;filename=" + HttpUtility.UrlEncode("c:\\a.doc", System.Text.Encoding.UTF8));

Response.AppendHeader("Content-Length", DownloadFile.Length.ToString());

Response.WriteFile(DownloadFile.FullName);

Response.Flush();

Response.End();

 

Content-Disposition：inline是直接打开，attachment是保存。
