為了強調和美化一組字符或句子，在字符或句子周圍應用邊框是一個不錯的選擇。Spire.Doc 使開發人員能夠在 C# 中實現此功能。并且有很多內置的邊框樣式可用，例如：Wave、Hairline、DotDash、DashSmallGap、DashLargeGap、DoubleWave、DashDotStroker、Emboss3D、Engrave3D、TwistedLines1 等等。下面的代碼展示了如何使用上面提到的一些邊框樣式來實現字符邊框： 

Spire.Doc for.NET 最新下載

注意：開始之前，請確保 Visual Studio 和 Spire.Doc 已正確安裝。我們將使用 Spire.Doc .dll 作為參考。

第一步：加載word文檔

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

第 2 步：添加應用邊框所需的字符并設置邊框樣式

//DashSmallGap Border
Paragraph para = section.AddParagraph();
para.Format.HorizontalAlignment = HorizontalAlignment.Left;
TextRange tr = para.AppendText("Spire.Doc for .Net");
tr.CharacterFormat.Border.BorderType = Spire.Doc.Documents.BorderStyle.DashSmallGap;
tr.CharacterFormat.Border.Color = Color.Green;
tr.CharacterFormat.FontSize = 24;
tr.CharacterFormat.TextColor = Color.DarkKhaki;
para.AppendBreak(BreakType.LineBreak);

//Wave Border
para = section.AddParagraph();
para.Format.HorizontalAlignment = HorizontalAlignment.Left;
tr = para.AppendText("Spire.PDF for .Net");
tr.CharacterFormat.Border.BorderType = Spire.Doc.Documents.BorderStyle.Wave;
tr.CharacterFormat.Border.Color = Color.Aqua;
tr.CharacterFormat.FontSize = 24;
tr.CharacterFormat.TextColor = Color.BurlyWood;
para.AppendBreak(BreakType.LineBreak);

//Emboss3D Border
para = section.AddParagraph();
para.Format.HorizontalAlignment = HorizontalAlignment.Left;
tr = para.AppendText("Spire.XLS for .Net");
tr.CharacterFormat.Border.BorderType = Spire.Doc.Documents.BorderStyle.Emboss3D;
tr.CharacterFormat.FontSize = 24;
para.AppendBreak(BreakType.LineBreak);

//DashDotStroker Border
para = section.AddParagraph();
para.Format.HorizontalAlignment = HorizontalAlignment.Left;
tr = para.AppendText("Spire.Office for .Net");
tr.CharacterFormat.Border.BorderType = Spire.Doc.Documents.BorderStyle.DashDotStroker;
tr.CharacterFormat.Border.Color = Color.Olive;
tr.CharacterFormat.FontSize = 24;
tr.CharacterFormat.TextColor = Color.Olive;
para.AppendBreak(BreakType.LineBreak);

//DoubleWave Border
para = section.AddParagraph();
para.Format.HorizontalAlignment = HorizontalAlignment.Left;
tr = para.AppendText("Spire.Presentation for .Net");
tr.CharacterFormat.Border.BorderType = Spire.Doc.Documents.BorderStyle.DoubleWave;
tr.CharacterFormat.Border.Color = Color.Blue;
tr.CharacterFormat.FontSize = 24;
tr.CharacterFormat.TextColor = Color.Blue;
para.AppendBreak(BreakType.LineBreak);

第 3 步：保存并啟動 word 文檔

doc.SaveToFile("S1.docx", FileFormat.Docx);
System.Diagnostics.Process.Start("S1.docx");
