上传服务器的数字名称的附件下载时还原原来的名称

首先定义一个新的页面a.aspx，来获得附件的实际名称和原来的名称

获得的附件信息为：“20131201020222.doc|通知.doc”，然后调用下面的方法，即可实现。

<a href='../a.aspx?fileServerName=" + s[1] + "&fileName=" + s[0] + "'>" + s[0] + "</a> <br/>"

 

 

  ///<summary>
    /// Response.AddHeader实现下载
    ///</summary>
    ///<param name="filePath">完整的文件路径</param>
    ///<param name="fileName">文件名</param>
    privatevoid DownFile(string filePath, string fileName)
    {
        FileInfo fileInfo =new FileInfo(filePath);
        Response.Clear();
        Response.ClearContent();
        Response.ClearHeaders();
        Response.AddHeader("Content-Disposition", "attachment;filename="+ fileName);
        Response.AddHeader("Content-Length", fileInfo.Length.ToString());
        Response.AddHeader("Content-Transfer-Encoding", "binary");
        Response.ContentType ="application/octet-stream";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
        Response.WriteFile(fileInfo.FullName);
        Response.Flush();
        Response.End();
    }
