xps 문서를 병합하면 마지막 하나가 복제됩니다.

Question

여러 개의 XPS 문서를 하나로 병합 할 때 문제가 있습니다. 병합 할 때 결과 xps에는 복제 된 마지막 XPS 문서가 들어 있습니다.

public XpsDocument CreateXPSStream(List<XpsDocument> ListToMerge) 
    { 
     var memoryStream = new MemoryStream(); 
     Package container = Package.Open(memoryStream, FileMode.Create); 
     string pack = "pack://temp.xps"; 
     PackageStore.RemovePackage(new Uri(pack)); 
     PackageStore.AddPackage(new Uri(pack), container); 

     XpsDocument xpsDoc = new XpsDocument(container, CompressionOption.SuperFast, "pack://temp.xps"); 
     FixedDocumentSequence seqNew = new FixedDocumentSequence(); 
     foreach (var sourceDocument in ListToMerge) 
     { 
      FixedDocumentSequence seqOld = sourceDocument.GetFixedDocumentSequence(); 
      foreach (DocumentReference r in seqOld.References) 
      { 
       DocumentReference newRef = new DocumentReference(); 
       ((IUriContext)newRef).BaseUri = ((IUriContext)r).BaseUri; 
       newRef.Source = r.Source; 
       seqNew.References.Add(newRef); 
      } 
     } 
     XpsDocumentWriter xpsWriter = XpsDocument.CreateXpsDocumentWriter(xpsDoc); 
     xpsWriter.Write(seqNew); 
     //xpsDoc.Close(); 
     //container.Close(); 
     return xpsDoc; 
    } 

결과가 DocumentViewer로 이동하고 사용자에게 표시 : 여기에 병합 내 기능 (Modified version of this question)입니다.

나는 다음과 같은 함수를 만들었고 나를 위해 작동합니다.

public void MergeXpsDocument(string newFile, List<XpsDocument> sourceDocuments) 
    { 
     if (File.Exists(newFile)) 
     { 
      File.Delete(newFile); 
     } 

     XpsDocument xpsDocument = new XpsDocument(newFile, System.IO.FileAccess.ReadWrite); 
     XpsDocumentWriter xpsDocumentWriter = XpsDocument.CreateXpsDocumentWriter(xpsDocument); 
     FixedDocumentSequence fixedDocumentSequence = new FixedDocumentSequence(); 

     foreach(XpsDocument doc in sourceDocuments) 
     { 
      FixedDocumentSequence sourceSequence = doc.GetFixedDocumentSequence(); 
      foreach (DocumentReference dr in sourceSequence.References) 
      { 
       DocumentReference newDocumentReference = new DocumentReference(); 
       newDocumentReference.Source = dr.Source; 
       (newDocumentReference as IUriContext).BaseUri = (dr as IUriContext).BaseUri; 
       FixedDocument fd = newDocumentReference.GetDocument(true); 
       newDocumentReference.SetDocument(fd); 
       fixedDocumentSequence.References.Add(newDocumentReference); 
      } 
     } 
     xpsDocumentWriter.Write(fixedDocumentSequence); 
     xpsDocument.Close(); 
    }
