多级列表编号允许您使用嵌套编号格式化和组织文本。多级列表最常见的形式是标题编号，它用大纲列表概括整篇文章，经常出现在技术、学术和商业文档中。在本文中，您将学习如何在 C#、VB.NET 中使用 Spire.Doc 生成多级列表编号。

详细步骤：

第 1 步 : 创建一个新的 Word 文档，添加一个部分。

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

第 2 步：定义新的多级列表样式。设置其名称为levelstyle，设置ListType 为Numbered，设置level 属性的参数。此列表级别独立于样式运行并控制数字格式。

ListStyle listStyle = new ListStyle(document, ListType.Numbered);
listStyle.Name = "levelstyle";
listStyle.Levels[0].PatternType = ListPatternType.Arabic;
listStyle.Levels[1].NumberPrefix = "\x0000.";
listStyle.Levels[1].PatternType = ListPatternType.Arabic;
listStyle.Levels[2].NumberPrefix = "\x0000.\x0001.";
listStyle.Levels[2].PatternType = ListPatternType.Arabic;
document.ListStyles.Add(listStyle);

第 3 步：创建一个段落，将文本附加到段落并使用 Heading1 应用段落样式。将定义的列表样式“levelstyle”应用于此段落。

Paragraph paragraph = section.AddParagraph();
paragraph.AppendText("The first item");
paragraph.ApplyStyle(BuiltinStyle.Heading1);
paragraph.ListFormat.ApplyStyle("levelstyle");

第 4 步：重复第 3 步以向该文档添加更多段落。在这里，您需要将不同的 ListLevelNumber 设置为 1 或 2，以确保将子段落和子段落分配给不同的列表模板。

paragraph = section.AddParagraph();
paragraph.AppendText("The second item");
paragraph.ApplyStyle(BuiltinStyle.Heading1);
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("The first sub-item");
paragraph.ApplyStyle(BuiltinStyle.Heading2);
paragraph.ListFormat.ListLevelNumber = 1;
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("The second sub-item");
paragraph.ApplyStyle(BuiltinStyle.Heading2);
paragraph.ListFormat.ContinueListNumbering();
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("A sub-sub-item");
paragraph.ApplyStyle(BuiltinStyle.Heading5);
paragraph.ListFormat.ListLevelNumber = 2;
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("The third item");
paragraph.ApplyStyle(BuiltinStyle.Heading1);
paragraph.ListFormat.ApplyStyle("levelstyle");

第 5 步：保存文件。

document.SaveToFile(@"result.docx", FileFormat.Docx);

结果：

listStyle.Levels[1].NumberPrefix = "\x0000.";
listStyle.Levels[1].PatternType = ListPatternType.Arabic;
listStyle.Levels[2].NumberPrefix = "\x0000.\x0001.";
listStyle.Levels[2].PatternType = ListPatternType.Arabic;
document.ListStyles.Add(listStyle);

Paragraph paragraph = section.AddParagraph();
paragraph.AppendText("The first item");
paragraph.ApplyStyle(BuiltinStyle.Heading1);
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("The second item");
paragraph.ApplyStyle(BuiltinStyle.Heading1);
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("The first sub-item");
paragraph.ApplyStyle(BuiltinStyle.Heading2);
paragraph.ListFormat.ListLevelNumber = 1;
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("The second sub-item");
paragraph.ApplyStyle(BuiltinStyle.Heading2);
paragraph.ListFormat.ContinueListNumbering();
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("A sub-sub-item");
paragraph.ApplyStyle(BuiltinStyle.Heading5);
paragraph.ListFormat.ListLevelNumber = 2;
paragraph.ListFormat.ApplyStyle("levelstyle");

paragraph = section.AddParagraph();
paragraph.AppendText("The third item");
paragraph.ApplyStyle(BuiltinStyle.Heading1);
paragraph.ListFormat.ApplyStyle("levelstyle");

document.SaveToFile(@"result.docx", FileFormat.Docx);

}
}
