多級列表編號允許您使用嵌套編號格式化和組織文本。多級列表最常見的形式是標題編號，它用大綱列表概括整篇文章，經常出現在技術、學術和商業文檔中。在本文中，您將學習如何在 C#、VB.NET 中使用 Spire.Doc 生成多級列表編號。

詳細步驟：

第 1 步 ： 創建一個新的 Word 文檔，添加一個部分。

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

第 2 步：定義新的多級列表樣式。設置其名稱為levelstyle，設置ListType 為Numbered，設置level屬性的參數。此列表級別獨立于樣式運行并控制數字格式。

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：創建一個段落，將文本附加到段落并使用 Heading1 應用段落樣式。將定義的列表樣式“levelstyle”應用于此段落。

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

第 4 步：重復第 3 步以向該文檔添加更多段落。在這里，您需要將不同的 ListLevelNumber 設置為 1 或 2，以確保將子段落和子段落分配給不同的列表模板。

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。

公文。SaveToFile（@“result.docx”， FileFormat.Docx）;

結果：

完整代碼：

[C#]

using Spire.Doc;
using Spire.Doc.Documents;
namespace CreatList
{
class Program
{

static void Main(string[] args)
{
Document document = new Document();
Section section = document.AddSection();

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);

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);

}
}
}
