[英]Adding ImagePart to docx in ASP.Net C# Open Office XML
我不是Open Office XML的佼佼者,並且一直在努力嘗試將圖像添加到我正在C#/ ASP.Net中以編程方式生成的docx文件中。 我正在嘗試將徽標放在簡歷文本塊頂部。 當我只使用主要文本部分(resumeText)時,我的程序運行良好,但是當我添加代碼以嘗試添加圖像時,出現錯誤“文件'..'。docx無法打開,因為內容有問題,然后細節說“未聲明的前綴”,我以為我已經從另一個示例中正確復制了xml,但似乎無法正常工作,誰能看到我要去哪里了嗎?感謝您提供任何幫助,以下是相關代碼:
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)
{
string docXml =
@"<?xml version=""1.0"" encoding=""UTF-8"" standalone=""yes""?>
<w:document xmlns:w=""http://schemas.openxmlformats.org/wordprocessingml/2006/main"">

</w:document>";
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/>");
}
RelationshipId應該在那里,而不是imagesPath @ <a:blip r:embed=""" + imagesPath + @""" />
,您可以將其作為string relationshipId = mainPart.GetIdOfPart(imagePart)
進行獲取string relationshipId = mainPart.GetIdOfPart(imagePart)
您可以找到示例代碼@ msdn鏈接如何將圖片插入文字處理文檔
更新:您需要在兩個地方進行更改1)傳遞圖像部分的ID,如下所示: SetMainDocumentContent(mainPart, resumeText, mainPart.GetIdOfPart(newImage));
2)添加名稱空間,如下所示
