[绝对路径与相对路径修改],该怎么解决

                if (type == "jpg" || type == "JPG" || type == "gif" || type == "GIF" || type == "BMP" || type == "bmp" || type == "png") //判断是否为图片类型                {                    if (this.FileUpload1.PostedFile.ContentLength > 200 * 1024)                    {                        Response.Write("<script>alert('上传图片必须小于50k！');</script>");                        return "";                    }                    else                    {                        string path = "D:\\wwwroot\\CCMTV\\HuoDong\\angel\\".ToString(); //本地上传路径                        //string path = "E:\\kaoshi\\".ToString(); //获取上传文件的外网站发布                        fileName1 = "AmyShow/" + DateTime.Now.ToString("yyyyMMddhhmmss") + fileName.ToString();                        if (File.Exists("D:\\wwwroot\\CCMTV\\HuoDong\\angel\\AmyShow\\" + fileName1))//(这个地方做判断是不是 有这 张图片如果已经有图片 则不能上传 )                        {                            return "";                        }                        else                        {                            fileName1 = "AmyShow/" + DateTime.Now.ToString("yyyyMMddhhmmss") + fileName.ToString();                            this.FileUpload1.SaveAs(path + fileName1);//存储文件到磁盘                            // this.newPreview.InnerText. = "~/admin/img/" + fileName;//显示图片                            // this.newPreview.InnerHtml = "~/admin/img/" + fileName;//显示图片                        }                    }
