C#新手求助
这里有一个dat格式的文件，如何编程使其在pictureBox里面显示出图像来。谢谢~~


OpenFileDialog file = new OpenFileDialog();
if (file.ShowDialog() == DialogResult.OK)
{
//将图片读成文件流
FileStream fs = new FileStream(file.FileName, FileMode.Open);
byte[] b = new byte[int.Parse(fs.Length.ToString())];
//将文件流字节码放进数组
fs.Read(b,0,int.Parse(fs.Length.ToString()));
MemoryStream ms = new MemoryStream(b);
//转为图片
Image i = Bitmap.FromStream(ms, true);
pictureBox1.Image = i;
}


这个运行到Image i = Bitmap.FromStream(ms, true);这总是说参数无效。求解答！麻烦讲清楚点，谢谢！


[解决办法]

C# code

public static Image BytesToImage(byte[] bytes)        {            try            {                using (MemoryStream stream = new MemoryStream())                {                    stream.Write(bytes, 0, bytes.Length);                    Image image = Image.FromStream(stream);                    return image;                }            }            catch            {                return null;            }        }
