        //保存到本地的文件名称

        //文件要下载的路径

        //Ftp上面的文件名称相同

        private System.ComponentModel.IContainer components;
    
        //是否传输成功
        private bool I_Transfer;
        /**//// <summary>

        /// </summary>
        public bool b_Transfer
        {
            get
            {
                return I_Transfer;
            }
        }
        
        public frm_ReadAttach(string s1,string s2,string s3)
        {
            //
            // Windows 窗体设计器支持所必需的
            //
            
            InitializeComponent();

            //

        }
        protected override void Dispose( bool disposing )
        {

                if(components != null)
                {
