这次要实现的效果如下图,在程序启动时首先显示:
此窗体(闪屏)相当简单,我只是用一副图作为窗体背景,在程序启动时调用,为了模拟加载,用线程延时演示了一下加载百分比。
窗体(SplashScreen.xaml)的XAML代码如下:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="WpfQQ.SplashScreen"
xmlns:local="clr-namespace:WpfQQ"
x:Name="Window"
Title="SplashScreen" Height="97" Width="380" WindowStartupLocation="CenterScreen" WindowStyle="None"
Background="BurlyWood" BorderBrush="BurlyWood" BorderThickness="0" ShowInTaskbar="False" ResizeMode="NoResize">
<Grid Margin="0,0,0,0" Height="97" VerticalAlignment="Top" Width="380">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="0*"/>
</Grid.ColumnDefinitions>
<Image Margin="0,1,0.888,0" Source="loading.png" Stretch="Fill"/>
<Label Margin="150,33,31.888,37" x:Name="label2"
Content="{Binding Message, Source={x:Static local:MessageListener.Instance}}" Foreground="Black"/>
</Grid>
</Window>
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="WpfQQ.SplashScreen"
xmlns:local="clr-namespace:WpfQQ"
x:Name="Window"
Title="SplashScreen" Height="97" Width="380" WindowStartupLocation="CenterScreen" WindowStyle="None"
Background="BurlyWood" BorderBrush="BurlyWood" BorderThickness="0" ShowInTaskbar="False" ResizeMode="NoResize">
<Grid Margin="0,0,0,0" Height="97" VerticalAlignment="Top" Width="380">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="0*"/>
</Grid.ColumnDefinitions>
<Image Margin="0,1,0.888,0" Source="loading.png" Stretch="Fill"/>
<Label Margin="150,33,31.888,37" x:Name="label2"
Content="{Binding Message, Source={x:Static local:MessageListener.Instance}}" Foreground="Black"/>
</Grid>
</Window>
其中的label2我们用于显示加载百分比等信息。
在App.xaml.cs中调用:
protected override void OnStartup(StartupEventArgs e)
{
Splasher.Splash = new SplashScreen();
Splasher.ShowSplash();
for (int i = 0; i < 100; i++)
{
MessageListener.Instance.ReceiveMessage(string.Format("Loading {0}%,Please waiting", i+1));
Thread.Sleep(20);//延时
}
base.OnStartup(e);
}
