使用open xml將嵌入式圖表添加到word文檔中

Question

Word文檔包含嵌入式圖表，我想使用打開的xml將其他文檔複製並粘貼到相同的圖表中。我已經使用下面的代碼，但粘貼圖表後文件正在損壞。你會發現我的錯誤嗎？

這裏doc是我的原始文件WordprocessingDocument對象。

using (WordprocessingDocument wordprocessingDocument = 
      WordprocessingDocument.Create("C:\\Sample.docx", WordprocessingDocumentType.Document)) 
     { 
      MainDocumentPart mainPart = wordprocessingDocument.MainDocumentPart; 
      if (mainPart == null) 
      { 
       mainPart = wordprocessingDocument.AddMainDocumentPart(); 
       new Document(new Body()).Save(mainPart); 
      } 

      var chart = mainPart.AddNewPart<ChartPart>(); 
      chart.FeedData(doc.MainDocumentPart.ChartParts.First().GetStream()); 

      string type = doc.MainDocumentPart.ChartParts.ElementAt(0).EmbeddedPackagePart.ContentType; 
      var embdedPkgPart = mainPart.AddEmbeddedPackagePart(type); 
      embdedPkgPart.FeedData(doc.MainDocumentPart.ChartParts.ElementAt(0).EmbeddedPackagePart.GetStream()); 

      string rellId = mainPart.GetIdOfPart(chart); 
      string uyo = chart.CreateRelationshipToPart(embdedPkgPart); 
      uyo.ToString(); 

      AddChart(wordprocessingDocument, rellId); 
      wordprocessingDocument.MainDocumentPart.Document.Save();    
     } 
public static void AddChart(WordprocessingDocument wordDoc, string relId) 
    { 
     DocumentFormat.OpenXml.Wordprocessing.Drawing element = 
      new Drawing(
       new Inline(
       new Extent() 
       { 
        Cx = 5486400, 
        Cy = 3200400 
       }, 

       new DW.EffectExtent() 
       { 
        LeftEdge = 19050L, 
        TopEdge = 0L, 
        RightEdge = 19050L, 
        BottomEdge = 0L 
       }, 

       new DocProperties() 
       { 
        Id = (UInt32Value)5U, 
        Name = "Chart 5" 
       }, 

       new DocumentFormat.OpenXml.Drawing.Wordprocessing.NonVisualGraphicFrameDrawingProperties(
        new GraphicFrameLocks() { NoChangeAspect = true }), 

       new Graphic(
        new GraphicData(
         new DocumentFormat.OpenXml.Drawing.Charts.ChartReference() { Id = relId } 
       ) { Uri = "http://schemas.openxmlformats.org/drawingml/2006/chart" }) 
      ) 
       { 
        DistanceFromTop = (UInt32Value)0U, 
        DistanceFromBottom = (UInt32Value)0U, 
        DistanceFromLeft = (UInt32Value)0U, 
        DistanceFromRight = (UInt32Value)0U 
       } 

     ); 

     wordDoc.MainDocumentPart.Document.Body.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Paragraph(new DocumentFormat.OpenXml.Wordprocessing.Run(element))); 
    }

public static void WriteChartParts(MainDocumentPart sourcePart, MainDocumentPart destnPart) 
    { 
     var paras = sourcePart.Document.Descendants<DocumentFormat.OpenXml.Wordprocessing.Run>(); 
     var drawingElements = from run in paras 
           where run.Descendants<Drawing>().Count() != 0 
           select run.Descendants<Drawing>().First(); 

     sourcePart.ChartParts.ForAll(chartPart => 
     { 
      destnPart.AddPart<ChartPart>(chartPart, sourcePart.GetIdOfPart(chartPart)); 
     }); 

     drawingElements.ForAll(drw => 
     { 
      destnPart.Document.Body.Append((drw as OpenXmlElement).Clone() as OpenXmlElement); 
     }); 
     destnPart.Document.Save(); 
    }
