Getting content as Null in DFS C#

I have checked all other posts related to content download. I have also gone through DFS 6.5 development guide. My problem is while using Get method of Object service, I am getting the properties, but not the content. DataObject.Contents is null. There are no exception bieng thrown.I changed all possible combination of ContentProfile. I have checked it in FirstDoc, There is a PDF available. Please find the code below. Also find the complete contentprofile object is bieng passed. The content is PDF.

try

DataObject objData = null;

ObjectIdentitySet objectIdentitySet = CreateObjectIdentityFromObjectId(sObjectID);

OperationOptions operationOptions = new OperationOptions {

new Profile[]{

new ContentProfile { formatFilter = FormatFilter.ANY,

PageFilter.ANY,

PageModifierFilter.ANY,

RenditionTypeFilter.ANY,

RenditionOption.SERVER

new ContentTransferProfile { transferMode = ContentTransferMode.MTOM }};

DataPackage dataPackage = null;

using (OperationContextScope scope = new OperationContextScope(objectService.InnerChannel))

OperationContext.Current.OutgoingMessageHeaders.Add(new ServiceContextHeader());

//Call the DFS object service with input ObjectID, If result is not null, return the retreived object ID

if (dataPackage != null && dataPackage.DataObjects.Count() > 0)

return objData;

catch (FaultException<QueryServiceReference.SerializableException> ex)

throw new DFSException("Exception occured while getting object:" + sObjectID, ex);

catch (Exception exx)

throw new DFSException("Exception occured while getting object:" + sObjectID, exx);

Solved it, found the answer.

DFS by default avoids the content, loads only the property. All the code examples says about setting the formatFilter of conteny profile to "ANY" to make the documentum to download the content. But this alone will not work, It might work for DFC client but wont work for DFS

After setting the format filter to any, there is another property called formatfilterspecified. you need to set that feature to true as well. I think it is a boolean property which is given precedence irrespective of if you set the formatfilter property or not

this wont work

formatFilter = FormatFilter.ANY

But this will work

formatFilter = FormatFilter.ANY

formatFilterSpecified =true,

Out of curiosity have you tried using the DFS SDK .NET samples as the base lines as per

	public DataObject GetWithContent(ObjectIdentity objectIdentity, String geoLoc, ContentTransferMode transferMode)
	{
	ContentTransferProfile transferProfile = new ContentTransferProfile();
	transferProfile.Geolocation = geoLoc;
	transferProfile.TransferMode = transferMode;
	DemoServiceContext.SetProfile(transferProfile);

	ContentProfile contentProfile = new ContentProfile();
	contentProfile.FormatFilter = FormatFilter.ANY;
	contentProfile.UrlReturnPolicy = UrlReturnPolicy.PREFER;

	OperationOptions operationOptions = new OperationOptions();
	operationOptions.ContentProfile = contentProfile;
	operationOptions.SetProfile(contentProfile);

	ObjectIdentitySet objectIdSet = new ObjectIdentitySet();
	List<ObjectIdentity> objIdList = objectIdSet.Identities;
	objIdList.Add(objectIdentity);

	DataPackage dataPackage = objectService.Get(objectIdSet, operationOptions);
	DataObject dataObject = dataPackage.DataObjects[0];

	Content resultContent = dataObject.Contents[0];
	String contentClassName = resultContent.GetType().FullName;
	Console.WriteLine("Returned content as type " + contentClassName);
	if (contentClassName.Equals("Emc.Documentum.FS.DataModel.Core.Content.UrlContent"))
	{
	UrlContent urlContent = (UrlContent)resultContent;
	Console.WriteLine("Content ACS URL is: " + (urlContent.Url));
	}
	if (resultContent.CanGetAsFile())
	{
	FileInfo fileInfo = resultContent.GetAsFile();
	Console.WriteLine("Got content as file " + fileInfo.FullName);
	}
	else if (contentClassName.Equals("Emc.Documentum.FS.DataModel.Core.Content.UcfContent"))
	{
	UcfContent ucfContent = (UcfContent)resultContent;
	Console.WriteLine("Got content as file " + ucfContent.LocalFilePath);
	}
	return dataObject;
	}

from ObjectServiceDemo.cs
