采用WPFCRichTextBox的方式?
原标题:Paragraph formatting in a WPF RichTextBox?

我需要将段落格式应用于在内容丰富的方框中进行选择。 我的RTB将采取与StackOverflow的丰富文本箱相同的方式,用户可将案文打入RTB,但也可进入密码区。 考试和测验科将采用非常简单的格式处理编码组别,从而改变名词,并对整个组群适用一个背景图,类似于下文编码组中你看到的情况。

改变字体非常简单:

var textRange = new TextRange(rtb.Selection.Start, rtb.Selection.End);
textRange.ApplyPropertyValue(TextElement.FontFamilyProperty, "Consolas");
textRange.ApplyPropertyValue(TextElement.FontSizeProperty, 10D );

现在,我需要采用一些段落级格式。 我需要将这一段的比值定为0,因此,我没有在代码行之间找到一个空白线,我需要将这一段的背景说明。 我的问题是: 我可以说明如何从甄选中获取段落内容,以便我能够采用格式。

任何建议? 如何使用马林和背景特性的实例将令人难以置信。 感谢!

最佳回答

奥赫,这是容易的。 在答复中,稍加研究:

var textRange = new TextRange(TextBox.Selection.Start, TextBox.Selection.End);
textRange.ApplyPropertyValue(TextElement.FontFamilyProperty, "Consolas");
textRange.ApplyPropertyValue(TextElement.FontSizeProperty, 10D );
textRange.ApplyPropertyValue(Paragraph.MarginProperty, new Thickness(0));
textRange.ApplyPropertyValue(Paragraph.BackgroundProperty, "LightSteelBlue");

唯一的限制是,重点仍然只延伸到案文,而不是控制的适当方面。 我将这个问题搁置了几天;如果有人能够告诉我如何把背景扩大到控制的适当方面,我接受你对这个问题的答复。
