Paragraph (16)
In Word documents, indentation is a paragraph format used to adjust the distance between paragraph body and page margin. It includes left indent, right indent, first line indent and hanging indent. Left indent and right indent can be applied to all lines of a paragraph, while first line indent can only be applied to first line of a paragraph. As for the hanging indent, it can be applied to every line of the paragraph except the first one. This article introduces how to programmatically set paragraph indents in a Word document using Spire.Doc for .NET.

using Spire.Doc.Documents;
namespace WordIndent
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document doc = new Document();
//Load a sample Word document
doc.LoadFromFile("sample.docx");
//Get the first paragraph and set left indent
Paragraph para1 = doc.Sections[0].Paragraphs[0];
para1.Format.LeftIndent = 30;
//Get the second paragraph and set right indent
Paragraph para2 = doc.Sections[0].Paragraphs[1];
para2.Format.RightIndent = 30;
//Get the third paragraph and set first line indent
Paragraph para3 = doc.Sections[0].Paragraphs[2];
para3.Format.FirstLineIndent = 30;
//Get the fourth paragraph and set hanging indent
Paragraph para4 = doc.Sections[0].Paragraphs[3];
para4.Format.FirstLineIndent = -30;
