silverlight中的textblock和textbox 使用之tips

关于 TextBlock 中文本的换行：

1、使用前台XAML控制。

2、使用后台代码控制。

<TextBlock x:Name="text" Height="124" Margin="99,35,235,0" VerticalAlignment="Top" TextWrapping="Wrap">

<Run Foreground="#FF246300" Text="-  Hello World! "/><LineBreak/>

<Run Text=" "/><Run Foreground="#FF000777" Text=" -  Here is Lewis! "/><LineBreak/>

<Run Text=" "/><Run Foreground="#FF000777" Text=" -  How "/>

<Run Foreground="#FF000777" Text="a"/>

<Run Foreground="#FF000777" Text="re "/>

<Run Foreground="#FF000777" Text="y"/>

<Run Foreground="#FF000777" Text="ou? "/><LineBreak/>

<Run Text=" "/>

<Run Foreground="#FF000777" Text=" -  I'm "/>

<Run Foreground="#FF000777" Text="f"/>

<Run Foreground="#FF000777" Text="ine!"/></TextBlock>

tips: 1、可以看到，换行是通过 <LineBreak/>来控制的。

接着上面的示例，如何在后台设置，代码如下：

Run run = new Run();
run.Foreground = new SolidColorBrush(Colors.Orange);
run.Text = ("\nI'm a sentence added in c# code inside Inlines property!\nCan I be seen?");

// Choose one of three below to run:
// 1.No Text Property Setting Recover
// this.text.Inlines.Add(run);
//第一种情况：在原有的text后面追加内容

// 2.Text Property Setting Cover Setting in XAML
//this.text.Text = "\nI'm a sentence added in c# code inside Text property!\nCan I be seen?";
//this.text.Inlines.Add(run);
//第二种情况：替换掉原有的text ,后再追加内容

// 3.Text Property Setting Cover all Settings once
this.text.Inlines.Add(run);
this.text.Text = "\nI'm a sentence added in c# code inside Text property!\nCan I be seen?";

//第三种情况：Text属性覆盖了Run

这里展示了三种情况：
