如何在WPF中爲消息框設置不同樣式的字體

Question

如何獲得以下樣式的消息框非常好？該MessageBox function似乎不能做的伎倆

Answer 1

您可以使用窗口

這裏讓自己的通知對話框是一個簡單的例子我剛掀起一起

用法：

NotificationDialog.ShowNotification("Backup and Restor center" 
       , "You need to be an Administrator to run backup" 
       , "Use Fast User Switching to switch to an account with administrator privileges, or log off and log on as an administrator" 
       , NotifyIcon.Exclamation); 

代碼：

using System; 
using System.ComponentModel; 
using System.Drawing; 
using System.Reflection; 
using System.Runtime.CompilerServices; 
using System.Runtime.InteropServices; 
using System.Windows; 
using System.Windows.Interop; 
using System.Windows.Media.Imaging; 

namespace WpfApplication8 
{ 
    /// <summary> 
    /// Interaction logic for NotificationDialog.xaml 
    /// </summary> 
    public partial class NotificationDialog : Window, INotifyPropertyChanged 
    { 
     public static void ShowNotification(string title, string caption, string message, NotifyIcon icon) 
     { 
      NotificationDialog dialog = new NotificationDialog(); 
      dialog.Title = title; 
      dialog.Caption = caption; 
      dialog.Message = message; 
      dialog.Image = dialog.GetIcon(icon); 
      dialog.ShowDialog(); 
     } 

     private string _caption; 
     private string _message; 
     private BitmapSource _image; 

     private const int GWL_STYLE = -16; 
     private const int WS_SYSMENU = 0x80000; 
     [DllImport("user32.dll", SetLastError = true)] 
     private static extern int GetWindowLong(IntPtr hWnd, int nIndex); 
     [DllImport("user32.dll")] 
     private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); 

     public NotificationDialog() 
     { 
      DataContext = this; 
      InitializeComponent(); 
      Loaded += (s, e) => 
       { 
        var hwnd = new WindowInteropHelper(this).Handle; 
        SetWindowLong(hwnd, GWL_STYLE, GetWindowLong(hwnd, GWL_STYLE) & ~WS_SYSMENU); 
       }; 
     } 

     public string Caption 
     { 
      get { return _caption; } 
      set { _caption = value; NotifyPropertyChanged(); } 
     } 

     public string Message 
     { 
      get { return _message; } 
      set { _message = value; NotifyPropertyChanged(); } 
     } 


     public BitmapSource Image 
     { 
      get { return _image; } 
      set { _image = value; NotifyPropertyChanged(); } 
     } 

     private BitmapSource GetIcon(NotifyIcon iconType) 
     { 
      Icon icon = (Icon)typeof(SystemIcons).GetProperty(iconType.ToString(), BindingFlags.Public | BindingFlags.Static).GetValue(null, null); 
      return Imaging.CreateBitmapSourceFromHIcon(icon.Handle, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); 
     } 

     private void Button_Close_Click(object sender, RoutedEventArgs e) 
     { 
      DialogResult = true; 
     } 

     public event PropertyChangedEventHandler PropertyChanged; 
     public void NotifyPropertyChanged([CallerMemberName]string propertyName = null) 
     { 
      if (PropertyChanged != null) 
      { 
       PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); 
      } 
     } 
    } 

    public enum NotifyIcon 
    { 
     Application, 
     Asterisk, 
     Error, 
     Exclamation, 
     Hand, 
     Information, 
     Question, 
     Shield, 
     Warning, 
     WinLogo 
    } 

} 

的XAML：

<Window x:Class="WpfApplication8.NotificationDialog" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Height="239" Width="417" Title="{Binding Title}" ResizeMode="NoResize" > 
    <Grid> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="223*"/> 
      <RowDefinition Height="50"/> 
     </Grid.RowDefinitions> 
     <Button Content="Close" HorizontalAlignment="Right" Margin="0,0,10,7" Grid.Row="1" VerticalAlignment="Bottom" Width="75" Click="Button_Close_Click"/> 
     <StackPanel Margin="70,10,10,0"> 
      <TextBlock Text="{Binding Caption}" FontSize="20" Foreground="DarkBlue" TextWrapping="Wrap"/> 
      <TextBlock Margin="0,10,0,0" Text="{Binding Message}" TextWrapping="Wrap"/> 
     </StackPanel> 
     <Image Source="{Binding Image}" Stretch="None" HorizontalAlignment="Left" Height="52" Margin="6,10,0,0" VerticalAlignment="Top" Width="55"/> 
    </Grid> 
</Window> 

結果：

我不認爲這是對這種風格正式框架的支持，但對於建築的消息框狀的準則（包括該截圖中使用的特定字體）在這裏：User Interface Text。

另請參見此CodeProject文章：WPF TaskDialog Wrapper and Emulator。顯然，它使用本地Windows 7調用來生成正確的樣式。
