Hi,

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p> </o:p>

From your description, it seems that you want to convert the bytes[] to image, right?

<o:p> </o:p>

If so, you may try the following code snippet:

<o:p> </o:p>

public static byte[]

ConvertImageToByteArray(System.Drawing.Image imageToConvert,

ImageFormat formatOfImage)

{

byte[] Ret;

try

{

using (MemoryStream ms = new MemoryStream())

{

imageToConvert.Save(ms, formatOfImage);

Ret = ms.ToArray();

}

}

catch (Exception) { throw; }

return Ret;

}

<o:p> </o:p>

public static Image ConvertByteArrayToImage(byte[] byteArray)

{

if (byteArray != null)

{

MemoryStream ms = new MemoryStream(byteArray, 0,

byteArray.Length);

ms.Write(byteArray, 0, byteArray.Length);

return Image.FromStream(ms, true);

}

return null;

}

<o:p> </o:p>

Thanks.
