C# 在Word中绘制横线

1、在VS程序中引用dll文件，如下图：

2、在程序中键入如下代码内容：C#using Spire.Doc;using Spire.Doc.Documents;namespace AddHorizontalLine{ class Program { static void Main(string[] args) { //加载Word测试文档 Document doc = new Document(); doc.LoadFromFile("test.docx"); //获取节和段落 Section section = doc.Sections[0]; Paragraph paragraph = section.Paragraphs[4]; //添加横线 paragraph.AppendHorizonalLine(); //保存文档 doc.SaveToFile("output.docx"); System.Diagnostics.Process.Start("output.docx"); } }}VB.NETImports Spire.DocImports Spire.Doc.DocumentsNamespace AddHorizontalLine Class Program Private Shared Sub Main(args As String()) '加载Word测试文档 Dim doc As New Document() doc.LoadFromFile("test.docx") '获取节和段落 Dim section As Section = doc.Sections(0) Dim paragraph As Paragraph = section.Paragraphs(4) '添加横线 paragraph.AppendHorizonalLine() '保存文档 doc.SaveToFile("output.docx") System.Diagnostics.Process.Start("output.docx") End Sub End ClassEnd Namespace

3、执行程序，生成文档。在生成的结果文档中可查看已添加的横线效果，如图：
