Question

我需要将一个字符串数组写入编号列表，但是在文档的特定位置。

例如，数组是：

sentence[0] : Jonathan Spielberg
sentence[1] : Stephanie Black
sentence[2] : Marcus Smith
sentence[3] : Kylie Ashton
...

然后它应该写在特定的位置，让我们在标题＆＃34; A部分说。候选人姓名＆＃34;

A. Candidate's Name
     1.  Jonathan Spielberg
     2.  Stephanie Black
     3.  Marcus Smith
     4.  Kylie Ashton

到目前为止，我的逻辑是使用唯一标记，然后它将被数组替换和循环以写入编号列表。我们说唯一标记是######CANDIDATESNAME#####。我已经这样做了，但那不起作用。

我该怎么做才能对此进行编码？

P.S。：我有一个模板文档.doc / .docx用于唯一的章节标题，然后我只需要用编号列表填充它。

Answer 1

我建议你按照解决方案。

1）实现IReplacingCallback接口。 2）使用Range.Replace方法查找唯一标记。 3）Move the cursor到文本（唯一标记）并插入编号列表。

请阅读以下文档链接，并使用以下代码在唯一标记的位置插入编号列表。

Find and Replace

string[] list = new string[] { "Jonathan Spielberg", "Stephanie Black", "Marcus Smith", "Kylie Ashton" };

Document mainDoc = new Document(MyDir + "in.docx");
mainDoc.Range.Replace(new Regex("######CANDIDATESNAME#####"), new FindandInsertList(list), false);
mainDoc.Save(MyDir + " Out.docx");
//--------------------------------------
public class FindandInsertList : IReplacingCallback
{
    private string[] listitems;

    public FindandInsertList(string[] list)
    {
        listitems = list;
    }

    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 Buidler
        DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Document);

        builder.MoveTo((Run)runs[runs.Count - 1]);

        builder.ListFormat.List = e.MatchNode.Document.Lists.Add(ListTemplate.NumberDefault);


        foreach (string item in listitems)
        {
            builder.Writeln(item);
        }

        // End the bulleted list.
        builder.ListFormat.RemoveNumbers();

        // 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;
    }
}
