                   //获取指定元素
                     var imgElemet = driver.FindElement(By.ClassName("vcode-spin-img"));
                    // getImgFile(driver, imgElemet.Location.X - 8, imgElemet.Location.Y);
                    //截图
                    Screenshot screenshot = ((ITakesScreenshot)imgElemet).GetScreenshot();

                    var dirpath = @"C:\B2BImge";
                    if (!Directory.Exists(dirpath))
                    {
                        Directory.CreateDirectory(dirpath);
