将内容控件添加到现有段落

Question

我有一个方法，除了单词段落，段落内容和任何评论内容（如果有的话）。作为跟踪文档中哪些段落已被处理的手段，我试图在openxml注入段落中添加内容控件。它爆炸了，我不确定从哪里开始，因为我对openxml相当陌生。我的代码示例如下：

public void Handle(Paragraph paragraph, string docPartXml, string commentsPartXml) 
    { 

     var docXml = docPartXml; 
     var commentsXml = commentsPartXml; 

     using (var res = paragraph.Range.WithComCleanup()) 
     { 
      var range = res.Resource; 
      using (var packageStream = range.GetPackageStreamFromRange()) 
      using (var document = WordprocessingDocument.Open(packageStream, true)) 
      { 
       var pbody = document.MainDocumentPart.Document.Body; 
       pbody.InnerXml = docXml + "<w:p></w:p>"; // paragraphs are merged/combined w/o this 
       document.MainDocumentPart.Document.Save(); 

       WordprocessingCommentsPart commentsPart = null; 
       if (document.MainDocumentPart.WordprocessingCommentsPart == null) 
       { 
        commentsPart = document.MainDocumentPart.AddNewPart<WordprocessingCommentsPart>(); 
        document.MainDocumentPart.AddPart(commentsPart); 
        document.MainDocumentPart.Document.Save(); 
        commentsPart = document.MainDocumentPart.WordprocessingCommentsPart; 
        commentsPart.Comments = new Comments(); 
       } 
       if (commentsPart == null) 
        commentsPart = document.MainDocumentPart.WordprocessingCommentsPart; 

       commentsPart.Comments.InnerXml += commentsXml; 
       commentsPart.Comments.Save(); 

       document.MainDocumentPart.Document.Save(); 

       document.Package.Flush(); 
       XDocument xdoc = OpenXmlExtensions.OpcToFlatOpc(document.Package); 
       var openxml = xdoc.ToString(); 

       var validator = new OpenXmlValidator(); 
       var errors = validator.Validate(document); 

       // todo - provide more detailed info for the log 
       foreach (var err in errors) 
        _logger.Warn(err.Description, "OpenXml Injection"); 

       try 
       { 
        range.InsertXML(openxml); 
       } 
       catch (COMException e) 
       { 
        _logger.Error("Unable to insert xml into paragraph"); 
       } 
      } 
     } 
    }

用以下代码替换pbody.InnerXml = ...代码行，它工作正常。

pbody.RemoveAllChildren<Paragraph>(); 
pbody.RemoveAllChildren<SdtBlock>(); 
pbody.RemoveAllChildren<SdtProperties>(); 
var sdtBlock1 = new SdtBlock(); 
var sdtPr = new SdtProperties(
    new SdtAlias {Val = string.Format("{0}-{1}", "CC", hash)}, 
    new Tag {Val = string.Format("{0}-{1}", hash, "CC")}); 
         //new Lock(){ Val = LockingValues.ContentLocked}); 
sdtBlock1.AppendChild(sdtPr); 
var sdtContentBlock1 = new SdtContentBlock { 

InnerXml = docXml}; 
sdtBlock1.AppendChild(sdtContentBlock1); 

pbody.AppendChild(sdtBlock1);
