{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document doc = new Document();

//Load a sample Word document
doc.LoadFromFile(@"D:\Files\sample.docx");

//Get the first section
Section section = doc.Sections[0];

//Get the first paragraph and make it center-aligned
Paragraph p = section.Paragraphs[0];
p.Format.HorizontalAlignment = HorizontalAlignment.Center;

//Get the second paragraph and make it left-aligned
Paragraph p1 = section.Paragraphs[1];
p1.Format.HorizontalAlignment = HorizontalAlignment.Left;

//Get the third paragraph and make it right-aligned
Paragraph p2 = section.Paragraphs[2];
p2.Format.HorizontalAlignment = HorizontalAlignment.Right;

//Get the fourth paragraph and make it justified
Paragraph p3 = section.Paragraphs[3];
p3.Format.HorizontalAlignment = HorizontalAlignment.Justify;

//Save the document
doc.SaveToFile("WordAlignment.docx", FileFormat.Docx);
}
