Set Text Alignment-Left, Right, Center and Justify, in Word with C#/VB.NET

Text alignment is one kind of paragraph settings in Word. It includes four types, right, left, center and justify. Generally speaking, left is the default alignment style. However, the most frequently used style is justify alignment. In this post, I will introduce a simple method to set text alignment in Word with C#/VB.NET.

Actually, in order to make the layout will be more wonderful and contents to be clearer, people often set text alignment for their Word document. In a Word document, there will be several alignment styles used. For example, if there is a reference paragraph in document, we may set different alignment style for it from others.

In my example, I will show all the four alignment styles. The following steps show details. And a .NET Word component, Spire.Doc for .NET is used, so I have added its dll file as reference in project. 


  1. Create a Word document. Add section and add paragraph in this section.
  2. Add cue words to show others what I will do and append style heading 1 for it.
  3. Set alignment.  Firstly, add one paragraph and add text “Horizontal Alignment”. Then set style as heading 2 for this paragraph. Secondly, use foreach sentence to set four alignment styles for text. A, in order to make text be more obvious, I set one style, including font name, size and color. B, add paragraph and append text. Then, set alignment format. C, apply style for text.
  4. Save and launch file.

Main Coding:


using System;
using System.Drawing;
using Spire.Doc;
using Spire.Doc.Documents;

namespace TextAlignment
    class Align
        static void Main(string[] args)
            //Create Document
            Document document = new Document();

            //Add Section and Paragraph
            Section section = document.AddSection();
            Paragraph paragraph = section.AddParagraph();

            //Append Text
            paragraph.AppendText(“Text Alignment Setting”);

            //Append Alignment

            //Save and Launch

        static void AppendAligmentText(Section section, Document document)
            Paragraph paragraph = null;
            paragraph = section.AddParagraph();

            //Append Text
            paragraph.AppendText(“Horizontal Aligenment”);
            foreach (Spire.Doc.Documents.HorizontalAlignment align in Enum.GetValues(typeof(Spire.Doc.Documents.HorizontalAlignment)))

                //Set Style
                ParagraphStyle style = new ParagraphStyle(document);
                style.CharacterFormat.FontName = “Calibri”;
                style.CharacterFormat.FontSize = 13;
                style.CharacterFormat.TextColor = Color.DarkCyan;

                //Set Alignment
                Paragraph paragraph1 = section.AddParagraph();
                paragraph1.AppendText(“This text is “ + align.ToString());
                paragraph1.Format.HorizontalAlignment = align;

                //Apply Style
