我们网站上有介绍如何设置对齐、缩进和项目符号的文档。这篇文章向您介绍了如何在word文档中设置段落间距。

第一步：创建word文档。

Document document = new Document();
Section section = document.AddSection();

第 2 步：将第一段添加到文档中。

Paragraph paragraph = section.AddParagraph();
paragraph.AppendText("Thank you for requesting a trial version of Spire.Doc. The component will work normally except for an evaluation warning message. Once you purchase a license file, the evaluation warning will disappeare.");

第 3 步：设置第一段的行距。

paragraph.Format.LineSpacing = 20;

第4步：设置第一段的间距。

paragraph.Format.BeforeSpacing = 30;

第 5 步：设置第一段之后的间距

paragraph.Format.AfterSpacing = 15;

第 6 步：保存文档。

document.SaveToFile("result.doc", FileFormat.Doc);

完整代码：

using Spire.Doc;
using Spire.Doc.Documents;
namespace Spacing
{
class Program
{

static void Main(string[] args)
{
Document document = new Document();
Section section = document.AddSection();

//add the first paragraph
Paragraph paragraph = section.AddParagraph();
paragraph.AppendText("Thank you for requesting a trial version of Spire.Doc. The component will work normally except for an evaluation warning message. Once you purchase a license file, the evaluation warning will disappeare.");
paragraph.Format.FirstLineIndent = 20;

//set the Line spacing
paragraph.Format.LineSpacing = 20;

//set the Spacing Before
paragraph.Format.BeforeSpacing = 30;

//set the Spacing After
paragraph.Format.AfterSpacing = 15;

//add the second paragraph
Paragraph paragraph2 = section.AddParagraph();
paragraph2.AppendText("Spire.Doc (Pack) is a compilation of Spire.Doc for .NET, Spire.Doc for Silverlight and Spire.Doc for WPF. It is a professional and powerful Word component which enables you to generate, load, write, edit and save Word document on .NET, Silverlight and WPF.
