C＃字节数组到图像

Question

I need to create an Image from a Byte Array but I don't know how to do this. I tried to do it like this:

using (var ms = new MemoryStream(byteArrayIn))
{
    return Image.FromStream(ms);
}

But there was always the message that the parameter ms is not valid. The exact Exception message is:

 An unhandled exception of type 'System.ArgumentException' occurred in System.Drawing.dll

With this I am reading the Array from the database

byte[] bytes = ObjectToByteArray(reader["profilepicture"]);

private byte[] ObjectToByteArray(Object obj)
    {
        if (obj == null)
            return null;
        BinaryFormatter bf = new BinaryFormatter();
        using (MemoryStream ms = new MemoryStream())
        {
            bf.Serialize(ms, obj);
            return ms.ToArray();
        }
    }

Can anybody please help me with this problem?

Try this:

public Image byteArrayToImage(byte[] byteArrayIn)
{
     MemoryStream ms = new MemoryStream(byteArrayIn);
     Image returnImage = Image.FromStream(ms);
     return returnImage;
}
