交叉引用是指同一文档中其他地方的相关信息。您可以创建对任何现有项目的交叉引用，例如标题、脚注、书签、题注和编号段落。本文将向您展示如何使用 Spire.Doc 与 C# 和 VB.NET 创建对书签的交叉引用。

第 1 步：创建一个 Document 实例。

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

第 2 步：插入书签。

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

第 3 步：创建一个交叉引用字段，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";

第 4 步：添加一个段落，并将字段插入该段落。

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

第 5 步：在段落中插入一个 FieldSeparator 对象，作为字段中的分隔符。  

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

第 6 步：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);

第 7 步：在段落中插入一个 FieldEnd 对象，用于标记字段的结束。

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);

输出：

交叉引用显示为将读者带到引用项目的链接。

{

//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);

}
}
