本文实例讲述了Asp.net获取服务器指定文件夹目录文件并提供下载的方法。分享给大家供大家参考。具体实现方法如下：

       //临时数据表
       DataTable dt = new DataTable();
       dt.Columns.Add(\"FileName\");
      
       foreach (FileInfo fileInfo in files)
       {
    DataRow dr = dt.NewRow();
    dr[\"FileName\"] = fileInfo.Name;
    dt.Rows.Add(dr);

       }
       Repeater1.DataSource = dt;
       Repeater1.DataBind();
}

if (e.CommandName == \"down\")
{
    try
    {
     string DownloadFileName = \"~/uploads/\" + e.CommandArgument.ToString();//文件路径
     string filepath = Server.MapPath(DownloadFileName);
     string filename = Path.GetFileName(filepath);
     FileInfo file = new FileInfo(filepath);
     Response.Clear();
     Response.ContentType = \"application/octet-stream\";
     Response.AddHeader(\"Content-Disposition\", \"attachment; filename=\" + HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8));
     Response.AddHeader(\"Content-length\", file.Length.ToString());
     Response.Flush();
     Response.WriteFile(filepath);
    }
    catch
    {
 Response.Write(\"<script>alert(\'没有找到下载的源文件\')</script>\");
    }
}
