c# – 打开XML – 如何向docx文档添加水印

我试图拿一个现有的文档,如果一个标题不存在,创建一个,然后添加一个水印到标题“DRAFT”对角线.我已经按照 here发布了一个例子,我已经得到了代码,如果头已经存在,它将添加水印.

当前的问题是当我添加一个新的标题,添加对文档的引用,然后将水印添加到标题时,该文档将被破坏,不能再在Word 2010中打开.

要测试,我一直在做以下操作:在页面的主要部分使用文本“TestDoc”从单词本身创建一个新的单词文档.保存到我的桌面为“TestDoc.docx”并关闭该文件.然后我从Visual Studio运行该应用程序.以下代码将始终使其损坏.如果我在文件中添加了一个标题,没有文本,然后点击保存,水印将被正确显示.

这是我到目前为止

更新:

现在通过改变打开文件的方式来解决这个问题.当我们将Main功能改为:

static void Main(string[] args) { //var doc = WordprocessingDocument.Open(@”C:\Users\loggedinuser\Desktop\TestDoc.docx”,true); //AddWatermark(doc); //doc.MainDocumentPart.Document.Save(); byte[] sourceBytes = File.ReadAllBytes(@”C:\Users\loggedinuser\Desktop\TestDoc.docx”); MemoryStream inMemoryStream = new MemoryStream(); inMemoryStream.Write(sourceBytes,(int)sourceBytes.Length); var doc = WordprocessingDocument.Open(inMemoryStream,true); AddWatermark(doc); doc.MainDocumentPart.Document.Save(); doc.Close(); doc.Dispose(); doc = null; using (FileStream fileStream = new FileStream(@”C:\Users\loggedinuser\Desktop\TestDoc.docx”,System.IO.FileMode.Create)) { inMemoryStream.WriteTo(fileStream); } inMemoryStream.Close(); inMemoryStream.Dispose(); inMemoryStream = null; }

该文件现在正确打开.谢谢布拉德!
