Spire.Doc 教程：用C＃，VB.NET在Word中创建对书签的交叉引用

Step 1: 创建一个文档实例。

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

Step 2: 插入一个书签。

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

Step 3: 创建交叉引用字段，并通过书签名称将其链接到书签。

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

Step 4: 添加一个段落，并将该字段插入段落。

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

Step 5: 将FieldSeparator对象插入到段落中，该段落在字段中用作分隔符。

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

Step 6: 设置交叉引用字段的显示文本。

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

Step 7: 将FieldEnd对象插入段落，该段落用于标记字段的末尾。

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

Step 8: 保存到文件。

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

导出：交叉引用显示为将读者引用到引用项目的链接。
