本地弄了一个上传方法/// 将本地文件上传到指定的服务器(HttpWebRequest方法)
        /// </summary>
        /// <param name="address">文件上传到的服务器</param> address：接收文件的URL地址：http://192.168.16.135:80/AnGeoDatas/UC_upload.aspx
        /// <param name="fileNamePath">要上传的本地文件（全路径）</param> fileNamePath：要上传的本地文件，如：D:\\\\\\\test.rar
        /// <param name="saveName">文件上传后的名称</param> saveName：文件上传到服务器后的名称，如：200901011234.rar
        /// <param name="progressBar">上传进度条</param>
        /// <returns>成功返回1，失败返回0</returns>
