Converting byte to image and image to byte using C#

问题

currently i am working with ASP.NET and C# to store image into MySQL (using blob datatype). I'm storing it successfully into database, but now problem is, How can I retrieve that byte[] to image format ?

FUNCTION: code to convert byte[] to image

public Image byteArrayToImage(byte[] byteArrayIn)
    {
        MemoryStream ms = new MemoryStream(byteArrayIn);
        Image returnImage = Image.FromStream(ms); --> here gives me error as `parameter is not valid`
        return returnImage;

    }

retieved as datatable...

if (dt1.Rows.Count > 0)
        {
            byteArrayToImage((byte[]) dt1.Rows[0]["PortfolioSlideImages"]);
            //MemoryStream ms = new MemoryStream((byte[])dt1.Rows[0]["PortfolioSlideImages"]);
            //Image returnImage = Image.FromStream(ms);
            //return returnImage;
        }

回答1:

Try this function,

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