因此,我目前正在此处复制/粘贴一些代码:https://docs.microsoft.com/en-us/windows/uwp/get-started/display-customers-in-list-learning-track
代码如下:
xaml:
<ListView ItemsSource="{x:Bind Customers}"
HorizontalAlignment="Center"
VerticalAlignment="Center">
<ListView.ItemTemplate>
<DataTemplate x:DataType="local:Customer">
<TextBlock Text="{x:Bind Name}"/>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
关于x:Bind Customers
:它似乎并不会自动完成,因为它是错误的。
关于x:DataType="local:Customer"
:我收到错误消息The name "Customer" does not exist in the namespace "using:helloUWP"
cs:
namespace helloUWP
{
/// <summary>
/// An empty page that can be used on its own or navigated to within a Frame.
/// </summary>
///
public class Customer
{
public string Name { get; set; }
}
public sealed partial class MainPage : Page
{
public ObservableCollection<Customer> Customers { get; }
= new ObservableCollection<Customer>();
public MainPage()
{
this.InitializeComponent();
this.Customers.Add(new Customer() { Name = "Name1" });
}
}
}
我无法构建它。我想念什么或做错什么了?

要在XAML中使用自定义类,首先必须在根元素中声明适当的名称空间,例如Page
:
<Page ... xmlns:models="TheNamespaceWhereCustomerIs">
然后使用:
x:DataType="models:Customer"
