ParagraphFormat.LineUnitBefore property

获取或设置段落之前的间距(以网格线为单位)。

public double LineUnitBefore { get; set; }

例子

演示如何更改段落间距和缩进。

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
ParagraphFormat format = doc.FirstSection.Body.FirstParagraph.ParagraphFormat;

// 下面是五个不同的间距选项,以及它们的配置间接影响的属性。
// 1 - 左缩进:
Assert.AreEqual(format.LeftIndent, 0.0d);

format.CharacterUnitLeftIndent = 10.0;

Assert.AreEqual(format.LeftIndent, 120.0d);

// 2 - 右缩进:
Assert.AreEqual(format.RightIndent, 0.0d); 

format.CharacterUnitRightIndent = -5.5;

Assert.AreEqual(format.RightIndent, -66.0d);

// 3 - 悬挂缩进:
Assert.AreEqual(format.FirstLineIndent, 0.0d);

format.CharacterUnitFirstLineIndent = 20.3;

Assert.AreEqual(format.FirstLineIndent, 243.59d, 0.1d);

// 4 - 段落前的行间距:
Assert.AreEqual(format.SpaceBefore, 0.0d);

format.LineUnitBefore = 5.1;

Assert.AreEqual(format.SpaceBefore, 61.1d, 0.1d);

// 5 - 段落后的行间距:
Assert.AreEqual(format.SpaceAfter, 0.0d);

format.LineUnitAfter = 10.9;

Assert.AreEqual(format.SpaceAfter, 130.8d, 0.1d);

builder.Writeln("Lorem ipsum dolor sit amet, consectetur adipiscing elit, " +
                "sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.");
builder.Write("测试文档测试文档测试文档测试文档测试文档测试文档测试文档测试文档测试" +
              "文档测试文档测试文档测试文档测试文档测试文档测试文档测试文档测试文档测试文档");
