网格生成(c# UWP)

我是UWP编程新手。还有一些问题。

我有JSON与数据(订单)。有一些订单计数。

我需要生成带有文本字段的网格。

现在我有了这样的xaml:

 <StackPanel Height="1020" Width="350" BorderBrush="#FFFDFCFC" BorderThickness="0,0,1,0">
            <Grid Height="204" BorderBrush="#FFFBF8F8" BorderThickness="0,0,0,1">
                <TextBlock x:Name="date1" HorizontalAlignment="Left" TextAlignment="Center" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="350" Height="50" FontFamily="SF UI Display" FontSize="30" FontWeight="Light" Foreground="White" />
                <TextBlock x:Name="adress1" TextAlignment="Center"  HorizontalAlignment="Left" Margin="0,146,-1,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Height="58" Width="350" FontFamily="SF UI Display" FontSize="20" FontWeight="Light" Foreground="White" />
                <TextBlock x:Name="name1" HorizontalAlignment="Left" TextAlignment="Center" Margin="0,86,-1,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Height="60" Width="350" FontFamily="SF UI Display" FontSize="30" FontWeight="Light" Foreground="White" Padding="0,0,0,0"/>
            </Grid>
            <Grid Height="204" BorderBrush="#FFFBF8F8" BorderThickness="0,0,0,1">
                <TextBlock x:Name="date2" TextAlignment="Center" HorizontalAlignment="Left" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="350" Height="50" Foreground="White" FontFamily="SF UI Display" FontSize="30" FontWeight="Light" />
                <TextBlock x:Name="adress2" TextAlignment="Center" HorizontalAlignment="Left" Margin="0,145,-1,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Height="59" Width="350" FontFamily="SF UI Display" FontSize="20" FontWeight="Light" Foreground="White" />
                <TextBlock x:Name="name2" HorizontalAlignment="Left" Margin="0,87,-1,0" TextAlignment="Center"  TextWrapping="Wrap" Text="" VerticalAlignment="Top" Height="64" Width="350" FontFamily="SF UI Display" FontSize="30" FontWeight="Light" Foreground="White" Padding="0,0,0,50"/>
            </Grid>
            <Grid Height="204" BorderBrush="#FFFBF8F8" BorderThickness="0,0,0,1">
                <TextBlock x:Name="date3" HorizontalAlignment="Left" TextAlignment="Center" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="350" Height="50" Foreground="White" FontFamily="SF UI Display" FontSize="30" FontWeight="Light" />
                <TextBlock x:Name="adress3" HorizontalAlignment="Left" TextAlignment="Center" Margin="0,143,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="350" Height="61" FontFamily="SF UI Display" FontSize="20" FontWeight="Light" Foreground="White" />
                <TextBlock x:Name="name3" HorizontalAlignment="Left" TextAlignment="Center" Margin="0,86,-1,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Height="60" Width="350" FontFamily="SF UI Display" FontSize="30" FontWeight="Light" Foreground="White" Padding="0,0,0,50"/>
            </Grid>
            <Grid Height="204" BorderBrush="#FFFBF8F8" BorderThickness="0,0,0,1">
                <TextBlock x:Name="date4" HorizontalAlignment="Left" TextWrapping="Wrap" TextAlignment="Center" Text="" VerticalAlignment="Top" Width="350" Height="50" Foreground="White" FontFamily="SF UI Display" FontSize="30" FontWeight="Light"  />
                <TextBlock x:Name="adress4" HorizontalAlignment="Left" Margin="0,153,0,0" TextWrapping="Wrap" TextAlignment="Center" Text="TextBlock" VerticalAlignment="Top" Height="61" Width="342" FontFamily="SF UI Display" FontSize="20" FontWeight="Light" Foreground="White" />
                <TextBlock x:Name="name4" HorizontalAlignment="Left" TextAlignment="Center" Margin="0,86,-1,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Height="60" Width="350" FontFamily="SF UI Display" FontSize="30" FontWeight="Light" Foreground="White" Padding="0,0,0,50"/>
            </Grid>

并像这样下载数据到TextBlock:

try
{
    date1.Text = convertedDate;
    adress1.Text = orders[0].shipping.address_1.ToString() + "                     " + orders[0].shipping.address_2;
    name1.Text = orders[0].billing.first_name.ToString();
    string order =orders[0].ToFormattedJsonString();           
}
catch (Exception e)
{
    Debug.WriteLine(e.Message);
    Debug.WriteLine(e.StackTrace);
}
string date_2 = orders[1].date_created + "+0:00";
DateTime dt2 = DateTime.Parse(date_2);
string convertedDate2 = dt2.ToString("dd/MM/yyyy HH:mm:ss");
try
{
    date2.Text = convertedDate2;
    adress2.Text = orders[1].shipping.address_1.ToString() + "                     " + orders[1].shipping.address_2;
    name2.Text = orders[1].billing.first_name.ToString();
}
catch (Exception e)
{
    Debug.WriteLine(e.Message);
    Debug.WriteLine(e.StackTrace);
}

但这并不好。我如何计算json中有多少json对象并根据它生成网格，然后用data

填充它

我建议您阅读有关此主题的文章(或书籍)，但这里是关于如何做到这一点的简短总结。

这是没有MVVM，这将是下一步，在这里我专注于基础。

所以，对于重复的项目使用GridView(或ListView，如果适合的话):

<GridView Background="Black"  x:Name="OrdersGridView" >
    <GridView.ItemTemplate>
        <DataTemplate>
            <StackPanel>
                <TextBlock Text="{Binding Date}" />
                <TextBlock Text="{Binding Address}" />
                <TextBlock Text="{Binding Name}"/>
            </StackPanel>
        </DataTemplate>
    </GridView.ItemTemplate>
</GridView>

如你所见，我们在DataTemplate中使用了数据绑定(也就是{Binding})。

然后为Orders创建一个类:

public class Order {
    public DateTime Date { get; set; }
    public string Address { get; set; }
    public string Name { get; set; }
}
然后在后面的代码中为订单创建一个属性: 
public ObservableCollection<Order> Orders { get; set; }

然后填充订单并将GridView的ItemSource设置为项目(这将是您的json抓取代码，这里我硬编码一些东西，使其更容易理解…):

//Populate Orders: 
            Orders = new ObservableCollection<Order> { new Order { Address = "dsfsd", Date = DateTime.Now, Name = "Name" } ,
                 new Order { Address = "dsfsd", Date = DateTime.Now, Name = "Name" },
                  new Order { Address = "dsfsd", Date = DateTime.Now, Name = "Name" }
                };
            OrdersGridView.ItemsSource = Orders;

那么你应该学习MVVM，但这将是第一步。
