【问题标题】:How to write a Numbered List of Text in a specific location?如何在特定位置编写文本编号列表?
【发布时间】:2016-05-26 06:33:35
【问题描述】:

我需要将一个字符串数组写入编号列表,但位于文档的特定位置。

比如数组是:

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

那么它应该写在一个特定的位置,比如说在“A.候选人姓名”部分的标题下

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签,然后将其替换并由要写入编号列表的数组循环。假设唯一标签是######CANDIDATESNAME#####。我已经这样做了,但这不起作用。

我应该如何编写代码?

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

【问题讨论】:

  • 循环遍历元素并使用
  • 标签。还要把你的代码写成你正在写的东西......

【解决方案1】:

我建议您遵循解决方案。

1) 实现 IReplacingCallback 接口。 2) 使用 Range.Replace 方法查找唯一标签。 3)Move the cursor到文本(唯一标签)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签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;
    }
}
