【教程】Spire.Doc系列教程(6):C# 在Word中插入上下标
上下标常见于数学公式、化学表达式等科学公式中。使用Spire.Doc时,用户可以通过CharacterFormat类中SubSuperScript属性来将字符(串)设置为上标或下标。
//初始化Document对象,添加section和段落 Document doc = new Document(); Section sec = doc.AddSection(); Paragraph para = sec.AddParagraph(); //写入钠与水反应的化学反应方程式 para.AppendText("2Na+2H"); para.AppendText("2").CharacterFormat.SubSuperScript = SubSuperScript.SubScript;//2作为下标 para.AppendText("=2NaOH+H"); para.AppendText("2").CharacterFormat.SubSuperScript = SubSuperScript.SubScript;//2作为下标 para.AppendBreak(BreakType.LineBreak);//换行 //写入公式a^2+b^2=c^2 para.AppendText("a"); para.AppendText("2").CharacterFormat.SubSuperScript = SubSuperScript.SuperScript;//2作为上标 para.AppendText("+b"); para.AppendText("2").CharacterFormat.SubSuperScript = SubSuperScript.SuperScript;//2作为上标 para.AppendText("=c"); para.AppendText("2").CharacterFormat.SubSuperScript = SubSuperScript.SuperScript;//2作为上标 para.AppendBreak(BreakType.LineBreak);//换行 //写入公式an=Sn-Sn-1 para.AppendText("an"); para.AppendText("=S"); para.AppendText("n").CharacterFormat.SubSuperScript = SubSuperScript.SubScript;//n作为下标 para.AppendText("-S"); para.AppendText("n-1").CharacterFormat.SubSuperScript = SubSuperScript.SubScript;//n-1作为下标 //设置字体大小 foreach (var i in para.Items) { if (i is TextRange) { (i as TextRange).CharacterFormat.FontSize = 20; } } //保存文档 doc.SaveToFile("output.docx");
效果图如下:
