WPF中是否有标准的消息框,例如WinForms' System.Windows.Forms.MessageBox.Show()
,还是应该使用WinForms消息框?

Answers:
WPF等效于System.Windows.MessageBox
。它具有非常相似的接口,但是对参数和返回值使用其他枚举。
您可以使用此:
MessageBoxResult result = MessageBox.Show("Do you want to close this window?",
"Confirmation",
MessageBoxButton.YesNo,
MessageBoxImage.Question);
if (result == MessageBoxResult.Yes)
{
Application.Current.Shutdown();
}

MessageBox
在WPF中,WinForms的等效项称为System.Windows.MessageBox
。
就像其他人所说的MessageBox
那样,WPF名称空间(System.Windows
)中有一个。
问题在于,它是带有OK,Cancel等的相同旧消息框。Windows Vista和Windows 7已改为使用“任务对话框”。
不幸的是,任务对话框没有简单的标准界面。我使用CodeProject KB中的实现。
也许下面的代码有帮助:
using Windows.UI.Popups;
namespace something.MyViewModels
{
public class TestViewModel
{
public void aRandonMethode()
{
MyMessageBox("aRandomMessage");
}
public async void MyMessageBox(string mytext)
{
var dialog = new MessageDialog(mytext);
await dialog.ShowAsync();
}
}
}
Windows.UI.Popups
呢
如果您想拥有自己的漂亮wpf消息框:创建新的Wpf Windows
这是xaml:
<Window x:Class="popup.MessageboxNew"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:popup"
mc:Ignorable="d"
Title="" SizeToContent="WidthAndHeight" WindowStartupLocation="CenterScreen" WindowStyle="None" ResizeMode="NoResize" AllowsTransparency="True" Background="Transparent" Opacity="1"
>
<Window.Resources>
</Window.Resources>
<Border x:Name="MainBorder" Margin="10" CornerRadius="8" BorderThickness="0" BorderBrush="Black" Padding="0" >
<Border.Effect>
<DropShadowEffect x:Name="DSE" Color="Black" Direction="270" BlurRadius="20" ShadowDepth="3" Opacity="0.6" />
</Border.Effect>
<Border.Triggers>
<EventTrigger RoutedEvent="Window.Loaded">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="DSE" Storyboard.TargetProperty="ShadowDepth" From="0" To="3" Duration="0:0:1" AutoReverse="False" />
<DoubleAnimation Storyboard.TargetName="DSE" Storyboard.TargetProperty="BlurRadius" From="0" To="20" Duration="0:0:1" AutoReverse="False" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Border.Triggers>
<Grid Loaded="FrameworkElement_OnLoaded">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Border Name="Mask" CornerRadius="8" Background="White" />
<Grid x:Name="Grid" Background="White">
<Grid.OpacityMask>
<VisualBrush Visual="{Binding ElementName=Mask}"/>
</Grid.OpacityMask>
<StackPanel Name="StackPanel" >
<TextBox Style="{DynamicResource MaterialDesignTextBox}" Name="TitleBar" IsReadOnly="True" IsHitTestVisible="False" Padding="10" FontFamily="Segui" FontSize="14"
Foreground="Black" FontWeight="Normal"
Background="Yellow" HorizontalAlignment="Stretch" VerticalAlignment="Center" Width="Auto" HorizontalContentAlignment="Center" BorderThickness="0"/>
<DockPanel Name="ContentHost" Margin="0,10,0,10" >
<TextBlock Margin="10" Name="Textbar"></TextBlock>
</DockPanel>
<DockPanel Name="ButtonHost" LastChildFill="False" HorizontalAlignment="Center" >
<Button Margin="10" Click="ButtonBase_OnClick" Width="70">Yes</Button>
<Button Name="noBtn" Margin="10" Click="cancel_Click" Width="70">No</Button>
</DockPanel>
</StackPanel>
</Grid>
</Grid>
</Border>
</Window>
对于此文件的cs:
public partial class MessageboxNew : Window
{
public MessageboxNew()
{
InitializeComponent();
//second time show error solved
if (Application.Current == null) new Application();
Application.Current.ShutdownMode = ShutdownMode.OnExplicitShutdown;
}
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
DialogResult = true;
}
private void cancel_Click(object sender, RoutedEventArgs e)
{
DialogResult = false;
}
private void FrameworkElement_OnLoaded(object sender, RoutedEventArgs e)
{
this.MouseDown += delegate { DragMove(); };
}
}
然后创建一个使用该类的类:
public class Mk_MessageBox
{
public static bool? Show(string title, string text)
{
MessageboxNew msg = new MessageboxNew
{
TitleBar = {Text = title},
Textbar = {Text = text}
};
msg.noBtn.Focus();
return msg.ShowDialog();
}
}
现在您可以像下面这样创建您的消息框:
var result = Mk_MessageBox.Show("Remove Alert", "This is gonna remove directory from host! Are you sure?");
if (result == true)
{
// whatever
}
