【问题描述】：

我有这个xaml 文件：

<UserControl x:Class="SpectroCoin.Controls.AccountInfo"
    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"
    mc:Ignorable="d"
    xmlns:effects="clr-namespace:SpectroCoin.Effects"
    FontFamily="StaticResource PhoneFontFamilyNormal"
    FontSize="StaticResource PhoneFontSizeNormal"
    Foreground="StaticResource PhoneForegroundBrush"
    d:DesignHeight="130" d:DesignWidth="480">
    <UserControl.Resources>
        <Style x:Key="MainInfoStyle" TargetType="TextBlock">
            <Setter Property="FontSize" Value="32"/>
            <Setter Property="VerticalAlignment" Value="Bottom"/>
        </Style>
        <Style x:Key="ReservedInfoStyle" TargetType="TextBlock">
            <Setter Property="FontSize" Value="20"/>
            <Setter Property="VerticalAlignment" Value="Bottom"/>
        </Style>
    </UserControl.Resources>
    <Grid x:Name="LayoutRoot" Margin="0,0,0,0" >
        <StackPanel Orientation="Vertical" Grid.Column="0" Margin="0,0,0,0">
            <TextBlock FontSize="24" Text="Label" x:Name="txtLabel" Margin="0"/>
            <TextBlock FontSize="50" Text="Binding Account.AvailableStr" Margin="50,-10,0,0" Foreground="#FFF9AF28"/>
            <TextBlock FontSize="24" Margin="50,-15,0,0" Visibility="Binding ReservedVisibility">
                <Run Foreground="Gainsboro" Text="Binding LocalizedResources.reserved, Source=StaticResource LocalizedStrings, StringFormat='\0\ '"/>
                <Run Foreground="Gainsboro" Text="Binding Account.ReservedStr"/>
            </TextBlock>
        </StackPanel>
        <!-- 
             <Border BorderThickness="0"  Grid.Column="0" VerticalAlignment="Center" Height="50" Padding="0,0,0,5">
             <StackPanel Orientation="Horizontal" Grid.Column="0" Margin="5,0,0,0">
             <TextBlock FontSize="32" VerticalAlignment="Bottom" Text="Label" x:Name="txtLabel" Margin="0,0,20,0"/>
             <TextBlock FontSize="32" VerticalAlignment="Bottom" >
             <Run FontSize="32" Text="Binding Account.Available"></Run>
             <Run FontSize="20"  Foreground="Gainsboro" Text="Binding Account.Reserved, StringFormat=' (+0'"/>
             <Run FontSize="20"  Foreground="Gainsboro" Text="Binding LocalizedResources.reserved, Source=StaticResource LocalizedStrings, StringFormat='\0\)'"/>
             </TextBlock>
 -->
        <!--
                <TextBlock Text="Binding Account.Available" Style="StaticResource MainInfoStyle"/>
        <TextBlock Text="test" Style="StaticResource MainInfoStyle">
            <Run Text="Binding Account.Available"></Run>
        </TextBlock>
    </StackPanel>
</Border>-->
</Grid>
</UserControl>

我在另一个xaml 文件中使用AccountInfo 属性：(ScreenShot)

<phone:PanoramaItem Header="Binding LocalizedResources.balance, Source=StaticResource LocalizedString">
    <StackPanel Margin="15,0,0,0">
        <StackPanel Name="AccountsInfo">
            <local:AccountInfo x:Name="accountInfoo" Label="Binding LocalizedResources.Euro, Source=StaticRessource LocalizedStrings" Margin="0,0,0,12" Tap="accountInfo_Tap" />
        </StackPanel>
        <local:RateChart x:Name="rateChart" Height="324" Margin="-12,25,0,0" Width="417" />
    </StackPanel>
</phone:PanoramaItem>

但是，现在我需要在我的代码中添加AccountInfos，因为它们的数量每次都不同。如何将它们添加到我的代码中，而不是 xaml？

【参考方案1】：

有两种方法可以做到这一点：

创建一个用户控件并将其添加到堆栈面板中，如下面的 .xaml.cs 中

var myAccountInfoControl = new AccountInfo();
AccountsInfo.Children.Add(myAccountInfoControl);

或

有一个 itemcsontrol 而不是 stackpanel，其中 itemscontrol 的 itemspanel 包含您的 usercontrol 和 itemscontrol 的 itemssource 绑定到某个 LISTOFACCOUNTS 集合。
