Следующий пример заполняет ItemsControl список BackupDirectories, который я получаю из кода.
Как я могу изменить это, чтобы получить ту же информацию из файла app.config?
XAML:
<Window x:Class="TestReadMultipler2343.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Grid Margin="10">
<Grid.RowDefinitions>
<RowDefinition Height="30"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="120"/>
<ColumnDefinition Width="160"/>
</Grid.ColumnDefinitions>
<TextBlock
Grid.Row="0"
Grid.Column="0"
Text="Title:"/>
<TextBlock
Grid.Row="0"
Grid.Column="1"
Text="{Binding Title}"/>
<TextBlock
Grid.Row="1"
Grid.Column="0"
Text="Backup Directories:"/>
<ItemsControl
Grid.Row="1"
Grid.Column="1"
ItemsSource="{Binding BackupDirectories}"/>
</Grid>
</Window>
