Posted on by Community Member

Hi there

I have pictures in the data base (such as company logo) and I need to pass it to an external application which need the content as a System.Byte array.

How can I achieve such a thing?

Regards

Hey!

I tried to find answer on same question and found static method in ax 2012 SRSFrameworkServiceHelper::convertContainerToBytes() ( same code must be available on 2009 too).

private static System.Byte[] convertContainerToBytes(container _container) { System.IO.MemoryStream memStream; System.Byte[] bytes; Binary assemblyBinary; if (_container) { try { assemblyBinary = Binary::constructFromContainer(_container); memStream = assemblyBinary.getMemoryStream(); bytes = memStream.ToArray(); memStream.Close(); } catch (Exception::CLRError) { SRSProxy::handleClrException(Exception::Error); } return bytes; } return null; }

PS Ofc "_container" it is a blob data type.

I think that getMemoryStream() was added in AX 2012.

AX 2009 probably requires using the Binary class to write bytes one by one.

Yep, you are right, my solution only for ax 2012.

Good evening.

In order to resolve this issue in ax 2009 use BinData class.

System.Byte[] bytes; BinData binData; ; binData = new BinData(); binData.setData(<container>); bytes = System.Convert::FromBase64String(binData.base64Encode());

Hello, I just want post a solution for similar issue you mentioned.

My original problem was, that the mehod Binary::constructFromContainer(_container) returned this error “Microsoft.Dynamics.Ax.Xpp.InfoException: Error executing code: Binary (object), method constructFromContainer called with invalid parameters.”

I didn’t know, that this method expected a specific format of the given container.

I have solve this error with the code below:

public static System.Byte[] container2Byte(container value) { System.Byte[] byteArray = null; ContainerClass containerClass = new ContainerClass(value); container blobContainer = containerClass.toBlob(); Binary binary = Binary::constructFromContainer(blobContainer); using (System.IO.MemoryStream stream = binary.getMemoryStream()) { byteArray = stream.ToArray(); } return byteArray; }

And the vice versa way:

public static container byte2Container(System.Byte[] value) { container blobContainer; using (System.IO.MemoryStream stream = new System.IO.MemoryStream(value)) { Binary binary = Binary::constructFromMemoryStream(stream); blobContainer = binary.getContainer(); } return ContainerClass::blob2Container(blobContainer); }

Maybe this helps others with the same issue which I had.
