文本对齐是一个段落格式属性，它决定了整个段落中文本的外观。Microsoft Word 中有四种可用的文本对齐方式：左对齐、居中对齐、右对齐和两端对齐。在本文中，您将学习如何使用Spire.Doc for .NET以编程方式为 Word 文档中的段落设置不同的文本对齐方式。

在 Word 中对齐文本

• 创建一个文档实例。
• 使用Document.LoadFromFile()方法加载示例 Word 文档。
• 使用Document.Sections[]属性获取指定部分。
• 使用Section.Paragraphs[]属性获取指定段落。
• 使用Paragraph.Format属性获取段落格式
• 使用ParagraphFormat.HorizontalAlignment属性设置指定段落的文本对齐方式。
• 使用Document.SaveToFile()方法将文档保存到另一个文件。

[C＃]

using Spire.Doc;
using Spire.Doc.Documents;

namespace AlignText
{
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);
}
}
}
