WPF的MessageBox太丑了，自己定义了一个。

这是效果：

XAML:

< Window x:Class ="AgileToDo.UMessageBox"
        xmlns ="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x ="http://schemas.microsoft.com/winfx/2006/xaml"
        Title ="UMessageBox" Height ="130" Width ="280" WindowStyle ="None"    Background =" {x:Null} "
        ResizeMode ="NoResize"   x:Name ="main"
        AllowsTransparency ="True" WindowStartupLocation ="CenterScreen" >
     < Window.Triggers >
         < EventTrigger RoutedEvent ="Window.Loaded" >
             < BeginStoryboard >
                 < Storyboard Name ="sbOpShow" >
                     < DoubleAnimation
                     Storyboard.TargetName ="main"
                    Storyboard.TargetProperty ="Opacity"
                    From ="0" To ="0.8" Duration ="0:0:0.15" />
                 </ Storyboard >
             </ BeginStoryboard >
         </ EventTrigger >
     </ Window.Triggers >
     < Window.Resources >
     </ Window.Resources >

     < Border Background ="#F03A3A3A" Opacity ="1" CornerRadius ="3" >
             < Canvas >

             < Border Canvas.Top ="0" Height ="25" Width =" {Binding ElementName=main, Path=Width,UpdateSourceTrigger=PropertyChanged} "
                    BorderThickness ="0,0,0,1" BorderBrush ="#FFEFE2E2" >
                 < TextBlock x:Name ="lblTitle" Text ="test" HorizontalAlignment ="Left"
                           Foreground ="#FFCBBEBE" FontSize ="14"
                           VerticalAlignment ="Center" Margin ="5" />
             </ Border >
             < TextBlock x:Name ="lblMsg"
                       Foreground ="White" FontSize ="14"
                       TextWrapping ="Wrap" Text ="test"
                       HorizontalAlignment ="Center" Canvas.Left ="20"
                       Canvas.Top ="50"
                        />
             < Border BorderBrush ="#FF60C1C1" BorderThickness ="0.5" Height ="22"
                    Canvas.Bottom ="10" Canvas.Right ="85" MouseLeftButtonDown ="Yes_MouseLeftButtonDown"
                 Name ="border1" Width ="49" Background ="#FFC7C7C7" CornerRadius ="2" >
                 < TextBlock Text ="YES"   HorizontalAlignment ="Center" VerticalAlignment ="Center" />
             </ Border >
             < Border BorderBrush ="#FF60C1C1" BorderThickness ="0.5" Height ="22"
                    Canvas.Bottom ="10" Canvas.Right ="30" MouseLeftButtonDown ="No_MouseLeftButtonDown"
                Name ="border2" Width ="49" CornerRadius ="2" Background ="#FFC7C7D1" >
                 < TextBlock Text ="NO"   HorizontalAlignment ="Center" VerticalAlignment ="Center" />
             </ Border >
         </ Canvas >
     </ Border >
</ Window >
