在ASP.Net C＃Open Office XML中将ImagePart添加到docx

Question

我不是Open Office XML的佼佼者，并且一直在努力尝试将图像添加到我正在C＃/ ASP.Net中以编程方式生成的docx文件中。 我正在尝试将徽标放在简历文本块顶部。 当我只使用主要文本部分（resumeText）时，我的程序运行良好，但是当我添加代码以尝试添加图像时，出现错误“文件'..'。docx无法打开，因为内容有问题，然后细节说“未声明的前缀”，我以为我已经从另一个示例中正确复制了xml，但似乎无法正常工作，谁能看到我要去哪里了吗？感谢您提供任何帮助，以下是相关代码：

protected void ibtDownload_Click(object sender, ImageClickEventArgs e)
{
    string attachmentDir = "~/tempDwnlds/";
    string fileName = m_candidateUser.firstName + "_" + m_candidateUser.lastName + "_" + m_candidateUser.userID.ToString().Substring(0, 6);
    string imagesPath = Server.MapPath("Images/Logo1.jpg");
    CreateNewWordDocument(Server.MapPath(attachmentDir) + fileName + ".docx", Server.HtmlEncode(m_candidate.resume), imagesPath);       
}


public static void CreateNewWordDocument(string document, string resumeText, string imagesPath)
{
    using (WordprocessingDocument wordDoc = WordprocessingDocument.Create(document, WordprocessingDocumentType.Document))
    {
        // Set the content of the document so that Word can open it.
        MainDocumentPart mainPart = wordDoc.AddMainDocumentPart();
        ImagePart newImage = wordDoc.MainDocumentPart.AddImagePart("images/jpeg");
        using (Stream image = new FileStream(imagesPath, FileMode.Open, FileAccess.Read, FileShare.Read))
        {
            newImage.FeedData(image);
        }
        SetMainDocumentContent(mainPart, resumeText, imagesPath);
    }
}

// Set the content of MainDocumentPart.
public static void SetMainDocumentContent(MainDocumentPart part, string resumeText, string imagesPath)
{

    using (Stream stream = part.GetStream())
    {
        byte[] buf = (new UTF8Encoding()).GetBytes(docXml);
        stream.Write(buf, 0, buf.Length);
    }
}

public static string WrappableDocXText(string source)
{
    string nwln = Environment.NewLine;
    return source.Replace(nwln, "<w:br/>");
}

Answer 1

RelationshipId应该在那里，而不是imagesPath @ <a:blip r:embed=""" + imagesPath + @""" /> ，您可以将其作为string relationshipId = mainPart.GetIdOfPart(imagePart)进行获取string relationshipId = mainPart.GetIdOfPart(imagePart)

您可以找到示例代码@ msdn链接如何将图片插入文字处理文档

更新：您需要在两个地方进行更改1）传递图像部分的ID，如下所示： SetMainDocumentContent(mainPart, resumeText, mainPart.GetIdOfPart(newImage));

2）添加名称空间，如下所示
