        public byte[] GetFileToDocumentum(string documentumId)
        {
            DataPackage dataPackage = null;

dataObject = dataPackage.DataObjects[0];

                contentObj = dataObject.Contents[0];
            }
            catch (Exception ex) { throw ex; }

return contentObj.GetAsByteArray();
}

        private DataPackage GetDataPackage(string documentumId)
        {
            ObjectIdentity objectIdentity = new ObjectIdentity(new ObjectId(documentumId), _repository);

ObjectIdentitySet objectIdentitySet = new ObjectIdentitySet();
objectIdentitySet.AddIdentity(objectIdentity);

DataPackage dataPackage = null;

            try
            {
                PropertyProfile propertyProfile = new PropertyProfile(PropertyFilterMode.ALL);

Hello,

we have used the same approach (DFS-Client with Java).The problem is here that your program will run into out of memory exceptions if the file is very big because it loads it completely into the memory as bytearray...

If you will have ACS configured on the content server, you can stream your content from the methodserver to your client (see example) and you are able to stream it into a file.

Example:

content = objectContentSet.getContents().get(0);
        InputStream contentStream = null;
        if (content instanceof UrlContent) {
            UrlContent urlContent = (UrlContent) content;
            try {
                URL acsContentUrl = new URL(urlContent.getUrl());
                contentStream = acsContentUrl.openStream();

// do whatever with the stream...

...

We use that approach to stream the content directly to the browser so that the user can download the file without saving the content on the web application server...

I hope, this helps you.

Thanks,

Jens
