使用OpenXML插入图片到Word文档的标题

Question

我知道有同样的问题here，但答案有点含糊，并没有显示完整的源代码。我有一个生成标题的方法，但它不起作用（在图像位置显示x）。

public static void AddPicHeader(string docxFileName) { 
     using(WordprocessingDocument doc = WordprocessingDocument.Open(docxFileName, true)) { 
      var mainDocPart = doc.MainDocumentPart; 
      var imgPart = mainDocPart.AddImagePart(ImagePartType.Png, "rId999"); 
      var image = GetImageFromFile(logoFileName); 
      var imagePartID = mainDocPart.GetIdOfPart(imgPart); 
      GenerateImagePartContent(imgPart, image); 

      if(!mainDocPart.HeaderParts.Any()) { 
       mainDocPart.DeleteParts(mainDocPart.HeaderParts); 
       var newHeaderPart = mainDocPart.AddNewPart<HeaderPart>(); 
       var rId = mainDocPart.GetIdOfPart(newHeaderPart); 
       var headerRef = new HeaderReference { Id = rId }; 
       var sectionProps = doc.MainDocumentPart.Document.Body.Elements<SectionProperties>().LastOrDefault(); 
       if(sectionProps == null) { 
        sectionProps = new SectionProperties(); 
        doc.MainDocumentPart.Document.Body.Append(sectionProps); 
       } 
       sectionProps.RemoveAllChildren<HeaderReference>(); 
       sectionProps.Append(headerRef); 
       newHeaderPart.Header = GeneratePicHeader(imagePartID); 
       newHeaderPart.Header.Save(); 
      } 
     } 
    } 

    private static Header GeneratePicHeader(string relationshipId) { 
     var element = 
      new Drawing(
       new DW.Inline(
        new DW.Extent() { Cx = 990000L, Cy = 792000L }, 
        new DW.EffectExtent() { 
         LeftEdge = 0L, 
         TopEdge = 0L, 
         RightEdge = 0L, 
         BottomEdge = 0L 
        }, 
        new DW.DocProperties() { 
         Id = (UInt32Value)1U, 
         Name = "NIS Logo" 
        }, 
        new DW.NonVisualGraphicFrameDrawingProperties(
         new A.GraphicFrameLocks() { NoChangeAspect = true }), 
        new A.Graphic(
         new A.GraphicData(
          new PIC.Picture(
           new PIC.NonVisualPictureProperties(
            new PIC.NonVisualDrawingProperties() { 
             Id = (UInt32Value)0U, 
             Name = "nis.png" 
            }, 
            new PIC.NonVisualPictureDrawingProperties()), 
           new PIC.BlipFill(
            new A.Blip(
             new A.BlipExtensionList(
              new A.BlipExtension() { 
               Uri = 
                "{28A0092B-C50C-407E-A947-70E740481C1C}" 
              }) 
            ) { 
             Embed = relationshipId, 
             CompressionState = 
              A.BlipCompressionValues.Print 
            }, 
            new A.Stretch(
             new A.FillRectangle())), 
           new PIC.ShapeProperties(
            new A.Transform2D(
             new A.Offset() { X = 0L, Y = 0L }, 
             new A.Extents() { Cx = 990000L, Cy = 792000L }), 
            new A.PresetGeometry(
             new A.AdjustValueList() 
            ) { Preset = A.ShapeTypeValues.Rectangle })) 
         ) { Uri = "http://schemas.openxmlformats.org/drawingml/2006/picture" }) 
       ) { 
        DistanceFromTop = (UInt32Value)0U, 
        DistanceFromBottom = (UInt32Value)0U, 
        DistanceFromLeft = (UInt32Value)0U, 
        DistanceFromRight = (UInt32Value)0U, 
        EditId = "50D07946" 
       }); 

     var header = new Header(); 
     var paragraph = new Paragraph(); 
     var run = new Run(); 

     run.Append(element); 
     paragraph.Append(run); 
     header.Append(paragraph); 
     return header; 
    } 

也许有人处理打？

对不起，如果它不清楚我以前的答案（在链接的问题）。我会尽量让这个不太模糊。

要在标题中插入图像，必须添加一个ImagePart到HeaderPart，不以mainDocumentPart。

public static void AddPicHeader(string docxFileName) { 
    using(WordprocessingDocument doc = WordprocessingDocument.Open(docxFileName, true)) { 

     //var mainDocPart = doc.MainDocumentPart; 
     //var imgPart = mainDocPart.AddImagePart(ImagePartType.Png, "rId999"); 
     //var image = GetImageFromFile(logoFileName); 
     //var imagePartID = mainDocPart.GetIdOfPart(imgPart); 
     //GenerateImagePartContent(imgPart, image); 

     if(!mainDocPart.HeaderParts.Any()) { 
      mainDocPart.DeleteParts(mainDocPart.HeaderParts); 
      var newHeaderPart = mainDocPart.AddNewPart<HeaderPart>(); 

      // try this instead 
      var imgPart = newHeaderPart.AddImagePart(ImagePartType.Png, "rId999"); 
          ^^^^^^^^^^^^^ 
      var image = GetImageFromFile(logoFileName); 
      var imagePartID = newHeaderPart.GetIdOfPart(imgPart); 
           ^^^^^^^^^^^^^ 
      GenerateImagePartContent(imgPart, image); 


      var rId = mainDocPart.GetIdOfPart(newHeaderPart); 
      var headerRef = new HeaderReference { Id = rId }; 
      var sectionProps = doc.MainDocumentPart.Document.Body.Elements<SectionProperties>().LastOrDefault(); 
      if(sectionProps == null) { 
       sectionProps = new SectionProperties(); 
       doc.MainDocumentPart.Document.Body.Append(sectionProps); 
      } 
      sectionProps.RemoveAllChildren<HeaderReference>(); 
      sectionProps.Append(headerRef); 
      newHeaderPart.Header = GeneratePicHeader(imagePartID); 
      newHeaderPart.Header.Save(); 
     } 
    } 
}
