下列範例示範如何以程式設計方式設定 IsOptimalParagraphEnabled 屬性。

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));

// Enable automatic hyphenation.
flowDoc.IsHyphenationEnabled = true;
// Enable optimal paragraph layout.
flowDoc.IsOptimalParagraphEnabled = true;

Dim flowDoc As New FlowDocument(New Paragraph(New Run("A bit of text content...")))

' Enable automatic hyphenation.
flowDoc.IsHyphenationEnabled = True
' Enable optimal paragraph layout.
flowDoc.IsOptimalParagraphEnabled = True

備註

最佳段落配置是一項功能，可在 中 FlowDocument 配置段落，以便盡可能平均分散空白字元。 理論上，這會藉由消除可能會因為行對齊文字和其他版面配置常式而發生的分心空白字元，來提供優化的閱讀體驗。 最佳段落配置與屬性所代表 IsHyphenationEnabled 的自動斷字 (結合時特別有效) 。
