  在您的情况下，您需要实现IReplacingCallback接口来查找文本并将其替换为文档（rtf） . 使用以下代码示例来满足您的要求 .

  Document doc = new Document(MyDir + "input.rtf");
  
  FindandInsertDocument replacedoc = new FindandInsertDocument(MyDir + "document to be inserted.rtf");
  
  doc.Range.Replace(new Regex("text which needs to be replaced with document"), replacedoc, false); 
  
  doc.Save(MyDir + "Out.rtf");
  

  FindandInsertDocument类：

  private class FindandInsertDocument : IReplacingCallback
  {
      private String path;
  
      public FindandInsertDocument(String documentpath)
      {
          path = documentpath;
      }
  
      /// <summary>
      /// This method is called by the Aspose.Words find and replace engine for each match.
      /// </summary>
      ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
      {
          // This is a Run node that contains either the beginning or the complete match.
          Node currentNode = e.MatchNode;
  
          // The first (and may be the only) run can contain text before the match,
          // in this case it is necessary to split the run.
          if (e.MatchOffset > 0)
              currentNode = SplitRun((Run)currentNode, e.MatchOffset);
  
          // This array is used to store all nodes of the match for further removing.
          ArrayList runs = new ArrayList();
  
          // Find all runs that contain parts of the match string.
          int remainingLength = e.Match.Value.Length;
          while (
              (remainingLength > 0) &&
              (currentNode != null) &&
              (currentNode.GetText().Length <= remainingLength))
          {
              runs.Add(currentNode);
              remainingLength = remainingLength - currentNode.GetText().Length;
  
              // Select the next Run node.
              // Have to loop because there could be other nodes such as BookmarkStart etc.
              do
              {
                  currentNode = currentNode.NextSibling;
              }
              while ((currentNode != null) && (currentNode.NodeType != NodeType.Run));
          }
  
          // Split the last run that contains the match if there is any text left.
          if ((currentNode != null) && (remainingLength > 0))
          {
              SplitRun((Run)currentNode, remainingLength);
              runs.Add(currentNode);
          }
  
          // Create Document Builder and insert document
          DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Document);
          builder.MoveTo((Run)runs[runs.Count - 1]);
  
          Document doc = new Document(path);
          builder.InsertDocument(doc, ImportFormatMode.KeepSourceFormatting);
  
          // Now remove all runs in the sequence.
          foreach (Run run in runs)
              run.Remove();
  
          // Signal to the replace engine to do nothing because we have already done all what we wanted.
          return ReplaceAction.Skip;
      }
  
      private static Run SplitRun(Run run, int position)
      {
          Run afterRun = (Run)run.Clone(true);
          afterRun.Text = run.Text.Substring(position);
          run.Text = run.Text.Substring(0, position);
          run.ParentNode.InsertAfter(afterRun, run);
          return afterRun;
      }
  }

  Document docList=new Document("");//your file
  
  docList.appendDocument(tempDoc, ImportFormatMode.KEEP_SOURCE_FORMATTING);
