DocX – Add horizontal lines to Microsoft Word document programmatically

Following code provides basic example usage on adding horitzonal lines to your Word Documents programatically with C#.

static void HelloWorldInsertHorizontalLine()
{
    Console.WriteLine("\tHelloWorldInsertHorizontalLine()");

    // Create a new document.
    using (DocX document = DocX.Create(@"docs\HelloWorldInsertHorizontalLine.docx"))
    {
        // Insert a Paragraph into this document.
        Paragraph p = document.InsertParagraph();

        // Append some text and add formatting.
        p.Append("Hello World!^011Hello World!")
        .Font(new FontFamily("Times New Roman"))
        .FontSize(32)
        .Color(Color.Blue)
        .Bold();
        p.InsertHorizontalLine("double", 6, 1, "auto");

        Paragraph p1 = document.InsertParagraph();
        p1.InsertHorizontalLine("double", 6, 1, "red");
        Paragraph p2 = document.InsertParagraph();
        p2.InsertHorizontalLine("single", 6, 1, "red");
        Paragraph p3 = document.InsertParagraph();
        p3.InsertHorizontalLine("triple", 6, 1, "blue");
        Paragraph p4 = document.InsertParagraph();
        p4.InsertHorizontalLine("double", 3, 10, "red");


        // Save this document to disk.
        document.Save();
        Console.WriteLine("\tCreated: docs\\HelloWorldInsertHorizontalLine.docx\n");
    }
}

Above example is part of DocX Examples and can be found in DocX source package under Examples \ Program.cs. This example uses RelativeDirectory.cs class. It's required for the code sample to work and are included in the sources of DocX.

Keep that in mind when working with the code to either download the DocX package or change the code appropriately. Below you can find Relative Directory class just in case you have no access to sources.
