我們已經演示了如何在創建 word 文檔時添加一個全新的 TOC 。本文將向您展示如何將 TOC 插入到現有的帶有樣式的 Word 文檔中，并從 Word 文檔中刪除 TOC。

Spire.Doc for.NET 最新下載

交叉引用是指同一文檔中其他地方的相關信息。您可以創建對任何現有項目的交叉引用，例如標題、腳注、書簽、題注和編號段落。本文將向您展示如何使用 Spire.Doc 與 C# 和 VB.NET 創建對書簽的交叉引用。

第 1 步：創建一個 Document 實例。

Document doc = new Document();
Section section = doc.AddSection();

第 2 步：插入書簽。

Paragraph paragraph = section.AddParagraph();
paragraph.AppendBookmarkStart("MyBookmark");
paragraph.AppendText("Text inside a bookmark");
paragraph.AppendBookmarkEnd("MyBookmark");

第 3 步：創建一個交叉引用字段，并通過書簽名稱將其鏈接到書簽。

Field field = new Field(doc);
field.Type = FieldType.FieldRef;
field.Code = @"REF MyBookmark \p \h";

第 4 步：添加一個段落，并將字段插入該段落。

paragraph = section.AddParagraph();
paragraph.AppendText("For more information, see ");
paragraph.ChildObjects.Add(field);

第 5 步：在段落中插入一個 FieldSeparator 對象，作為字段中的分隔符。  

FieldMark fieldSeparator= new FieldMark(doc, FieldMarkType.FieldSeparator);
paragraph.ChildObjects.Add(fieldSeparator);

TextRange tr = new TextRange(doc);
tr.Text = "above";
paragraph.ChildObjects.Add(tr);

第 7 步：在段落中插入一個 FieldEnd 對象，用于標記字段的結束。

FieldMark fieldEnd = new FieldMark(doc, FieldMarkType.FieldEnd);
paragraph.ChildObjects.Add(fieldEnd);

第 8 步：保存到文件。

doc.SaveToFile("output.docx", FileFormat.Docx2013);

輸出：

交叉引用顯示為將讀者帶到引用項目的鏈接。

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
namespace CreatCR
{
class Program
{
static void Main(string[] args)
{
Document doc = new Document();
Section section = doc.AddSection();
//create a bookmark
Paragraph paragraph = section.AddParagraph();
paragraph.AppendBookmarkStart("MyBookmark");
paragraph.AppendText("Text inside a bookmark");
paragraph.AppendBookmarkEnd("MyBookmark");
//insert line breaks
for (int i = 0; i < 4; i++)
{
paragraph.AppendBreak(BreakType.LineBreak);
}
//create a cross-reference field, and link it to bookmark
Field field = new Field(doc);
field.Type = FieldType.FieldRef;
field.Code = @"REF MyBookmark \p \h";
//insert field to paragraph
paragraph = section.AddParagraph();
paragraph.AppendText("For more information, see ");
paragraph.ChildObjects.Add(field);
//insert FieldSeparator object
FieldMark fieldSeparator = new FieldMark(doc, FieldMarkType.FieldSeparator);
paragraph.ChildObjects.Add(fieldSeparator);
//set display text of the field
TextRange tr = new TextRange(doc);
tr.Text = "above";
paragraph.ChildObjects.Add(tr);
//insert FieldEnd object to mark the end of the field
FieldMark fieldEnd = new FieldMark(doc, FieldMarkType.FieldEnd);
paragraph.ChildObjects.Add(fieldEnd);
//save file
doc.SaveToFile("output.docx", FileFormat.Docx2013);

}
}
}
