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.NET

Imports Spire.Doc

Imports Spire.Doc.Documents

Namespace 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 Class

End 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：
