Question

我知道有同样的问题here，但答案有点模糊，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 header = new Header();
        var paragraph = new Paragraph();
        var run = new Run();

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

也许有人处理了打击？

很抱歉，如果我之前的回答不清楚（链接问题）。我会尽量使这个不那么模糊。

要在标题中插入图片，您必须将ImagePart添加到 HeaderPart ，而不是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();
        }
    }
}

如果像我这样的小份额，您的标头上只有一张图片可以替换为适当的徽标

Dim HeaderPart As HeaderPart = (From run In wordDoc.MainDocumentPart.HeaderParts Where run.ImageParts.Count = 1 Select run).FirstOrDefault
If HeaderPart IsNot Nothing Then
Dim ImagePart As ImagePart = HeaderPart.ImageParts(0)
    Dim imageBytes() As Byte = File.ReadAllBytes(PathNewImge)
    Dim writer As BinaryWriter = New BinaryWriter(ImagePart.GetStream())
    writer.Write(imageBytes)
    writer.Close()
End If

使用OpenXML将图片插入Word文档的标题
