最近项目上需要实现一个询问提示消息框，但猛的发现人家Silverlight类库提供的MessageBox类只有简单的两个重载方法，百思不得其解，不知为什么不提供，没有办法只有自己做一个，其实不是很难办，因为Silverlight3以后提供了ChildWindow，下面是实现代码，希望对大家有用。
<controls:ChildWindow x:Class="SilverlightMsgBox.MsgBoxWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls" Width="400" Height="160" Title="MsgBox">

<ColumnDefinition />

<TextBlock x:Name="msgBlock" HorizontalAlignment="Left" VerticalAlignment="Center" Grid.Column="1"></TextBlock>
<Image x:Name="imgIcon" Width="32" Height="32" HorizontalAlignment="Center" VerticalAlignment="Center" Source="png/Message.png" />
