Here i am trying to convert the .docx document bytearraay in to the form of a stream with the help of teh function(BinaryToStraemConverter) and then try to save the stream as DOc object.

It was working fine.. suddently it stopped working.. i am wondering why..

Please help me to do this.

Now it throwing an Error saying : Unknown file format. and showing the source as Aspose.dll

MemoryStream DocumentumStream = new MemoryStream();

DocumentumStream = this.BinaryToStraemConverter(DocumentumTemplateByteArray);

OutDoc = new Document(DocumentumStream); // Here it throwing the Error

Definition for BinaryToStraemConverter method:

public MemoryStream BinaryToStraemConverter(byte[] binaryArray)


MemoryStream stream_object_doc = new MemoryStream(binaryArray);
