将文件从一个位置复制到另一个位置并在放置时间戳后重命名 [ ^ ]

在我的观点中，您不能：您网站运行的用户的默认权限几乎肯定不会允许您访问服务器的根目录，您的网站无法在客户端上指定文件的存储位置（甚至如果它是存储的 - 这取决于用户）



为此我们有间接方式以下代码是从DB检索文件修改代码基于你的要求

In My point of view, you can't: The default permissions for the user your website is running under will almost certainly not allow you to access files in the root directory of your server, and your website cannot specify the storage location of a file on the client (or even if it is stored at all - that is up to the user)

For this we have indirect way the below code is retrieve file from DB Modify the Code based on your requirement

<![CDATA[<%  
    // Send a download file to the client given the filename.    
    string guid = Request.QueryString["file"];
    string fileName = "ERROR";
    byte[] data = new byte[] { 0, 0, 0, 0 };
    string strCon = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["DownloadDatabase"].ConnectionString;
    using (System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(strCon))
        {
        con.Open();
        string strcmd = "SELECT [iD] ,cn.[fileName],[description] ,[dataContent] ,[version] " +
                        "FROM dlContent cn " +
                        "WHERE cn.iD=@ID";
        using (System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand(strcmd, con))
            {
            cmd.Parameters.AddWithValue("@ID", guid);
            using (System.Data.SqlClient.SqlDataReader r = cmd.ExecuteReader())
                {
                if (r.Read())
                    {
                    fileName = (string) r["filename"];
                    data = (byte[]) r["dataContent"];
                    }
                }
            }
        }
    Response.Clear();
    Response.AddHeader("Cache-Control", "no-cache, must-revalidate, post-check=0, pre-check=0");
    Response.AddHeader("Pragma", "no-cache");
    Response.AddHeader("Content-Description", "File Download");
    Response.AddHeader("Content-Type", "application/force-download");
    Response.AddHeader("Content-Transfer-Encoding", "binary\n");
    Response.AddHeader("content-disposition", "attachment;filename=" + fileName);
    Response.BinaryWrite(data);
    Response.End();
