概要
书签的设置可以帮助我们快速的定位某段文字,使用起来很方便,也很节省时间。在前一篇文章“C# 如何添加/删除Word书签”中介绍了插入、删除书签的方法,本篇文章将对C# 操作Word书签的功能做进一步介绍。示例内容将包含以下要点:
- 在现有书签位置插入图片
- 在现有书签位置插入表格
- 读取书签位置的文档内容
- 替换现有书签位置内容
使用工具
- Spire.Doc for .NET 6.1
- Visual Studio
ps:下载安装该类库后,注意添加引用Spire.Doc.dl到项目程序,dll文件可在安装路径的Bin文件夹中获取。
示例代码(供参考)
测试文档如下:
【示例1】 在现有书签位置插入图片
步骤 1: 添加using指令
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;
步骤 2 :主要代码段
//创建实例,加载文档
Document document = new Document();
document.LoadFromFile("test.docx"); //实例化BookmarksNavigator类,指定需要添加图片的书签“Bookmark1”
BookmarksNavigator bn = new BookmarksNavigator(document);
bn.MoveToBookmark("Bookmark1", true, true); //添加段落,加载图片并插入到段落
Section section0 = document.AddSection();
Paragraph paragraph = section0.AddParagraph();
Image image = Image.FromFile("img.png");
DocPicture picture = paragraph.AppendPicture(image);
bn.InsertParagraph(paragraph);
document.Sections.Remove(section0); //保存文档并打开
string output = "result.docx";
document.SaveToFile(output, FileFormat.Docx);
System.Diagnostics.Process.Start(output);
图片插入效果:
全部代码:
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing; namespace InsertImgToBookmark_Doc
{
class Program
{
static void Main(string[] args)
{
//创建实例,加载文档
Document document = new Document();
document.LoadFromFile("test.docx"); //实例化BookmarksNavigator类,指定需要添加图片的书签“Bookmark1”
BookmarksNavigator bn = new BookmarksNavigator(document);
bn.MoveToBookmark("Bookmark1", true, true); //添加段落,加载图片并插入到段落
Section section0 = document.AddSection();
Paragraph paragraph = section0.AddParagraph();
Image image = Image.FromFile("img.png");
DocPicture picture = paragraph.AppendPicture(image);
bn.InsertParagraph(paragraph);
document.Sections.Remove(section0); //保存文档并打开
string output = "result.docx";
document.SaveToFile(output, FileFormat.Docx);
System.Diagnostics.Process.Start(output);
}
}
}
【示例 2】在现有书签位置插入表格
步骤 1:添加using指令
using Spire.Doc;
using Spire.Doc.Documents;
using System.Data;
步骤 2 :创建文档,加载文件
Document doc = new Document();
doc.LoadFromFile("test.docx");
步骤 3 :创建表格
//创建Table对象
Table table = new Table(doc, true); //创建模拟数据
DataTable dt = new DataTable();
dt.Columns.Add("PI", typeof(string));
dt.Columns.Add("Type", typeof(string));
dt.Columns.Add("Nov.", typeof(string));
dt.Columns.Add("YTD", typeof(string));
dt.Rows.Add(new string[] { "PI","Type", "Nov.", "YTD" });
dt.Rows.Add(new string[] { "", "BAIC EC-Series", "15.719", "64.910" });
dt.Rows.Add(new string[] { "", "Tesla Model S", "3.889", "46.951" });
dt.Rows.Add(new string[] { "", "Nissan Leaf", "2.817", "46.423" }); //将数据填充至表格
table.ResetCells(dt.Rows.Count, dt.Columns.Count);
for (int i = ; i < dt.Rows.Count; i++)
{
for (int j = ; j < dt.Columns.Count; j++)
{
table.Rows[i].Cells[j].AddParagraph().AppendText(dt.Rows[i][j].ToString());
}
}
步骤 4 :插入表格到书签位置
//获取指定书签位置
BookmarksNavigator navigator = new BookmarksNavigator(doc);
navigator.MoveToBookmark("origin2"); //将表格添加至TextBodyPart
TextBodyPart part = navigator.GetBookmarkContent();
part.BodyItems.Add(table);
//替换原有书签内容
navigator.ReplaceBookmarkContent(part);
步骤 5 :保存文件
//保存并打开文件
doc.SaveToFile("output.docx", FileFormat.Docx2013);
System.Diagnostics.Process.Start("output.docx");
表格插入效果:
全部代码:
using Spire.Doc;
using Spire.Doc.Documents;
using System.Data; namespace InsertTableToBookmark_Doc
{
class Program
{
static void Main(string[] args)
{
//创建文档,加载文件
Document doc = new Document();
doc.LoadFromFile("test.docx"); //创建Table对象
Table table = new Table(doc, true); //创建模拟数据
DataTable dt = new DataTable();
dt.Columns.Add("PI", typeof(string));
dt.Columns.Add("Type", typeof(string));
dt.Columns.Add("Nov.", typeof(string));
dt.Columns.Add("YTD", typeof(string));
dt.Rows.Add(new string[] { "PI","Type", "Nov.", "YTD" });
dt.Rows.Add(new string[] { "", "BAIC EC-Series", "15.719", "64.910" });
dt.Rows.Add(new string[] { "", "Tesla Model S", "3.889", "46.951" });
dt.Rows.Add(new string[] { "", "Nissan Leaf", "2.817", "46.423" }); //将数据填充至表格
table.ResetCells(dt.Rows.Count, dt.Columns.Count);
for (int i = ; i < dt.Rows.Count; i++)
{
for (int j = ; j < dt.Columns.Count; j++)
{
table.Rows[i].Cells[j].AddParagraph().AppendText(dt.Rows[i][j].ToString());
}
} //获取指定书签位置
BookmarksNavigator navigator = new BookmarksNavigator(doc);
navigator.MoveToBookmark("origin2"); //将表格添加至TextBodyPart
TextBodyPart part = navigator.GetBookmarkContent();
part.BodyItems.Add(table); //替换书签内容
navigator.ReplaceBookmarkContent(part); //保存并打开文件
doc.SaveToFile("output.docx", FileFormat.Docx2013);
System.Diagnostics.Process.Start("output.docx");
}
}
}
【示例3】读取书签位置的内容
步骤 1 :添加using指令
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System;
步骤 2 :获取书签位置的内容
//初始化BookmarkNavigator类对象
BookmarksNavigator navigator = new BookmarksNavigator(doc);
//定位到指定书签位置,获取书签位置的文档内容
navigator.MoveToBookmark("bookmark1");
TextBodyPart textBodyPart = navigator.GetBookmarkContent();
步骤 3 :读取书签内容
//遍历书签内容中的子项目,并将文本信息提取至string类型变量中
string text = null;
foreach (var item in textBodyPart.BodyItems)
{
if (item is Paragraph)
{
foreach (var childObject in (item as Paragraph).ChildObjects)
{
if (childObject is TextRange)
{
text += (childObject as TextRange).Text;
}
}
}
}
//控制台输出文本
Console.WriteLine(text);
Console.ReadLine();
读取结果:
全部代码:
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System; namespace GetTextOfBookmark_Doc
{
class Program
{
static void Main(string[] args)
{
//实例化Document类,加载测试文档
Document doc = new Document();
doc.LoadFromFile("test.docx"); //初始化BookmarkNavigator类对象
BookmarksNavigator navigator = new BookmarksNavigator(doc);
//定位到指定书签位置,获取书签位置的文档内容
navigator.MoveToBookmark("bookmark1");
TextBodyPart textBodyPart = navigator.GetBookmarkContent(); //遍历书签内容中的子项目,并将文本信息提取至string类型变量中
string text = null;
foreach (var item in textBodyPart.BodyItems)
{
if (item is Paragraph)
{
foreach (var childObject in (item as Paragraph).ChildObjects)
{
if (childObject is TextRange)
{
text += (childObject as TextRange).Text;
}
}
}
}
//控制台输出文本
Console.WriteLine(text);
Console.ReadLine();
}
}
}
【示例4】替换现有书签内容
步骤 1 :添加using指令
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
步骤 2 :加载文档
Document document = new Document();
document.LoadFromFile("test.docx");
步骤 3 :添加段落及文字
Section sec = document.AddSection();//添加section
sec.AddParagraph().AppendText("Welcome Back, \n My Friend!"); //添加段落到section,并添加字符串内容
步骤 4 :获取段落
//获取段落内容
ParagraphBase firstReplacementParagraph = sec.Paragraphs[].Items.FirstItem as ParagraphBase;
ParagraphBase lastReplacementParagraph = sec.Paragraphs[sec.Paragraphs.Count - ].Items.LastItem as ParagraphBase;
//实例化类TextBodySelection和TextBodyPart
TextBodySelection selection = new TextBodySelection(firstReplacementParagraph, lastReplacementParagraph);
TextBodyPart part = new TextBodyPart(selection);
步骤 5 :替换书签内容
BookmarksNavigator bookmarkNavigator = new BookmarksNavigator(document);//实例化BookmarksNavigator类
bookmarkNavigator.MoveToBookmark("bookmark1", true, true);//定位到书签“bookmark1”所在段落的位置
bookmarkNavigator.DeleteBookmarkContent(true);//删除原有书签位置的内容
bookmarkNavigator.ReplaceBookmarkContent(part, true, true);//用新添加段落的内容替换掉原书签的内容并保留格式
document.Sections.Remove(sec); //移除section
步骤 6 :保存文档
//保存文档并打开
document.SaveToFile("替换书签.docx");
System.Diagnostics.Process.Start("替换书签.docx");
替换效果:
全部代码:
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields; namespace EditOrReplaceBookmark_Doc
{
class Program
{
static void Main(string[] args)
{
//创建Document类实例,加载文档
Document document = new Document();
document.LoadFromFile("test.docx"); Section sec = document.AddSection();//添加section
sec.AddParagraph().AppendText("Welcome Back, \n My Friend!"); //添加段落到section,并添加字符串内容 //获取段落内容
ParagraphBase firstReplacementParagraph = sec.Paragraphs[].Items.FirstItem as ParagraphBase;
ParagraphBase lastReplacementParagraph = sec.Paragraphs[sec.Paragraphs.Count - ].Items.LastItem as ParagraphBase;
//实例化类TextBodySelection和TextBodyPart
TextBodySelection selection = new TextBodySelection(firstReplacementParagraph, lastReplacementParagraph);
TextBodyPart part = new TextBodyPart(selection); BookmarksNavigator bookmarkNavigator = new BookmarksNavigator(document);//实例化BookmarksNavigator类
bookmarkNavigator.MoveToBookmark("bookmark1", true, true);//定位到书签“bookmark1”所在段落的位置
bookmarkNavigator.DeleteBookmarkContent(true);//删除原有书签位置的内容
bookmarkNavigator.ReplaceBookmarkContent(part, true, true);//用新添加段落的内容替换掉原书签的内容并保留格式
document.Sections.Remove(sec); //移除section //保存文档并打开
document.SaveToFile("替换书签.docx");
System.Diagnostics.Process.Start("替换书签.docx");
}
}
}
