上传图片文件（支持远程存储）

在项目是，需要将图片保存到另外一台服务器上，很痛苦！

最后通过FileInfo实现！

　　　　　/// <summary>
        /// 保存文件到远程服务器
        /// </summary>
        /// <param name="filepath1">文件路径，通常通过FileUpLoad.PostedFile.FileName得到</param>
        public void CopyPic(string filepath1)
        {
            string filepath = filepath1;
            if (filepath == string.Empty)
            {
                //MessageBox.Show("图片路径不能为空!");
                return;
            }
            FileInfo info = new FileInfo(filepath);
            string imgpath = "PCPersonnel/";
            string dirpath = "//192.168.0.250/U_HomeImage/" + imgpath;
            try
            {
                if (!Directory.Exists(dirpath))
                {
                    Directory.CreateDirectory(dirpath);
                }
                info.CopyTo(dirpath + info.Name, true);
                //txtSingle.Text = imgpath + info.Name;
                //MessageBox.Show("图片上传成功!");

            }
            catch (Exception ex)
            {
                //lblShow.Show();
                //this.lblShow.Text = "图片上传失败,失败原因:" + ex.Message;
            }
        }

　　如果保存图片在本地更简单了

///fileLoad为FileUpLoad文件
if (this.fileLoad.FileName.Length > 0)
                {
                    if (!Directory.Exists(Server.MapPath("picture/PCPersonnel")))
                        Directory.CreateDirectory(Server.MapPath("picture/PCPersonnel"));
                    //this.DeletePicture();
                    HttpPostedFile hpf = this.fileLoad.PostedFile;
                    string strext = new FileInfo(hpf.FileName).Extension;
                    Random rad = new Random(5);
                    string strpath = string.Format("{0}-{1:X4}-{2:X8}{3}", "" + DateTime.Now.ToString("yyyyMMddHHmmss"), DateTime.Now.Millisecond, rad.GetHashCode(), strext);
                    
                    hpf.SaveAs(Server.MapPath("picture/PCPersonnel/" + strpath));
                    //this.Picture.InnerText = strpath;
                    picPath = "PCPersonnel/" + strpath;
                }
