求助，从本机获取文件上传到服务器上取不到正确路径问题
 protected void FileUpload()
        {
            string webPathFile = Server.MapPath(Request.Url.AbsolutePath);//该处始终取得不到服务器的正确路径，求解？？？

            webPath = webPathFile.Substring(0, webPathFile.LastIndexOf("\\") + 1) + "EXCEL" + "\\";

            
            for (int x = 0; x <ListExcelName.Items.Count;x++ )
            {
                FileUpload(ListExcelName.Items[x].Text.ToString(), webPath);
            }       

        }
        public void FileUpload(string localPathFile, string webPhysicalPathFile)//localPathFile是本地物理文//件 webPhysicalPathFile是服务器物理路径 
        {

            FileStream inStream = null;

            FileStream outStream = null;

            try
            {

                string fileName = localPathFile.Substring(localPathFile.LastIndexOf("\\") + 1);

                //读取本地文件流
 
                    inStream = File.OpenRead(localPathFile);

                    string file = webPhysicalPathFile + fileName;//得到网络服务器的文件路径名；

                    outStream = new FileStream(file, FileMode.OpenOrCreate, FileAccess.Write);

                    byte[] bytes = new byte[4096];

                    int start = 0;

                    int length;

                    while ((length = inStream.Read(bytes, 0, 4096)) > 0)
                    {
                        outStream.Write(bytes, 0, length);
