爲什麼ObjectDataProvider在本例中沒有識別「local：Customer」？爲什麼我在這個數據綁定中得到「類型引用無法找到公共類型」？
當我鍵入
<local:
我得到 「客戶」 智能感知所以它應該工作。在這個例子中我沒有代碼隱藏。
XAML：
<Window x:Class="TestDataTemplate124.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:TestDataTemplate124"
Title="Window1" Height="300" Width="300">
<Window.Resources>
<ObjectDataProvider x:Key="Customers"
ObjectType="x:Type local:Customer"
MethodName="GetAllCustomers"/>
</Window.Resources>
<StackPanel>
<ListBox DataContext="{StaticResource Customers}" ItemsSource="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding FirstName}"/>
<TextBlock Text=" "/>
<TextBlock Text="{Binding LastName}"/>
<TextBlock Text=" ("/>
<TextBlock Text="{Binding Age}"/>
<TextBlock Text=")"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</Window>
Customer.cs：
using System.Collections.ObjectModel;
namespace TestDataTemplate124
{
public class Customer
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int Age { get; set; }
public static ObservableCollection<Customer> GetAllCustomers()
{
ObservableCollection<Customer> customers = new ObservableCollection<Customer>();
customers.Add(new Customer() { FirstName = "Jim", LastName = "Smith", Age = 23 });
customers.Add(new Customer() { FirstName = "John", LastName = "Jones", Age = 22 });
customers.Add(new Customer() { FirstName = "Jay", LastName = "Anders", Age = 21 });
return customers;
}
}
