将图片文件显示到界面

       //显示图片方法一，当另一个地方也需要读取此图片时会报文件被占用的错
       //FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read);
       //pbCapture.Image = Image.FromStream(fileStream); //pbCapture是System.Windows.Forms.PictureBox
       //pbCapture.Tag = fileName;
       //fileStream.Close();
       //fileStream.Dispose();

　　//显示图片方法二，推荐使用

       pbCapture.Image = ExtendHelper.FileToImg(fileName); //pbCapture是System.Windows.Forms.PictureBox

        public static Image FileToImg(string imageName)
        {
            try
            {
                FileStream s = new FileStream(imageName, FileMode.Open);
                var img = new Bitmap(s);
                s.Close();
                return img;
            }
            catch (Exception ex)
            {
                LogHelper.logger.Error($"FileToImg({imageName})", ex);
                return null;
            }
        }
