例子

演示如何将页面设置设置应用和恢复到文档中的各个部分。

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// 修改构建器当前部分的页面设置属性并添加文本。
builder.PageSetup.Orientation = Orientation.Landscape;
builder.PageSetup.VerticalAlignment = PageVerticalAlignment.Center;
builder.Writeln("This is the first section, which landscape oriented with vertically centered text.");

// 如果我们使用文档生成器开始一个新部分，
// 它将继承构建器的当前页面设置属性。
builder.InsertBreak(BreakType.SectionBreakNewPage);

Assert.AreEqual(Orientation.Landscape, doc.Sections[1].PageSetup.Orientation);
Assert.AreEqual(PageVerticalAlignment.Center, doc.Sections[1].PageSetup.VerticalAlignment);

// 我们可以使用“ClearFormatting”方法将其页面设置属性恢复为其默认值。
builder.PageSetup.ClearFormatting();

Assert.AreEqual(Orientation.Portrait, doc.Sections[1].PageSetup.Orientation);
Assert.AreEqual(PageVerticalAlignment.Top, doc.Sections[1].PageSetup.VerticalAlignment);

builder.Writeln("This is the second section, which is in default Letter paper size, portrait orientation and top alignment.");

doc.Save(ArtifactsDir + "PageSetup.ClearFormatting.docx");
