我正在用c#编写项目，并在silverlight3中进行设计..

我有三个切换按钮:粗体"，斜体"，下划线"


我已经完成了粗体和斜体的编码


void _btnBold1_Click(对象发送者，RoutedEventArgs e)
{
试试

如果(_btnBold1.IsChecked.HasValue)
{

推荐答案

尝试使用-
txtMailBody1.TextDecorations=TextDecorations.Underline;

Try using something like -
txtMailBody1.TextDecorations=TextDecorations.Underline;

如果这是组件一个富文本框-请查看其文档

If this is the Component one rich text box - have a look at their documentation here.

They provide the following solution.
You need to do the same

private void _btnUnderline_Click(object sender, RoutedEventArgs e)
{
bool underline = _rtb.Selection.TextDecorations ==
TextDecorations.Underline;
_rtb.Selection.TextDecorations = underline
? null
: TextDecorations.Underline;
}

您的代码将如下所示-txtMailBody1.Selection.TextDecorations == TextDecoration.Underline;

Your code will be something like this - txtMailBody1.Selection.TextDecorations == TextDecoration.Underline;
