获取WPF Listview以使用数据绑定显示ObservableCollection <T>

Question

我有一个类型为Project的可观察集合,我希望在ListView中显示但是没有添加到我的ListView中,我真的不明白

我的MainWindow.xaml

            <ListView Name="ListViewProjects" Grid.Column="0" Grid.RowSpan="3" SelectionChanged="ListViewProjectsSelectionChanged" ItemsSource="{Binding}" IsSynchronizedWithCurrentItem="True" MinWidth="100">
            <ListView.ItemTemplate>
                <DataTemplate>
                    <WrapPanel>
                        <TextBlock Text="{Binding Path=ProjectID}"/>
                        <TextBlock Text="{Binding Path=ProjectName}"/>
                    </WrapPanel>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>

我的MainWindow.cs

    public partial class MainWindow : Window
{
    ObservableCollection<Project> Projects = new ObservableCollection<Project>();
    ObservableCollection<Employee> Employees = new ObservableCollection<Employee>();

    public MainWindow()
    {
        InitializeComponent();

        DataContext = Projects;

        Project pro1 = new Project(1, "Swordfish");
        Projects.Add(pro1);
        Employee empMads = new Employee("Mads", 1);
        Employee empBrian = new Employee("Brian", 2);
        Employees.Add(empMads);
        Employees.Add(empBrian);
    }

    private void ListViewProjectsSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
    }
}

和我的Project.cs这是类文件

[Serializable]
class Project : INotifyPropertyChanged
{
    public Project(int id, string name)
    {
        ID = id;
        Name = name;
    }

    private int id;
    public int ID
    {
        get { return id; }
        set
        {
            id = value;
            NotifyPropertyChanged("ProjectID");
        }
    }

    private string name;
    public string Name
    {
        get { return name; }
        set
        {
            name = value;
            NotifyPropertyChanged("ProjectName");
        }
    }

    [field: NonSerialized]
    public event PropertyChangedEventHandler PropertyChanged;

    private void NotifyPropertyChanged(String info)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(info));
        }
    }
}

但是没有任何内容添加到我的列表中我无法看到我错过了它的工作.

我有它作为observablecollection我做DataContext =集合我在xaml文件中绑定

编辑代码部分1:

        public ObservableCollection<Project> Projects { get; set; }
    public ObservableCollection<Employee> Employees { get; set; }

    public MainWindow()
    {
        InitializeComponent();
        Projects = new ObservableCollection<Project>();
        Employees = new ObservableCollection<Employee>();

        DataContext = Projects;

Answer 1

这是因为您使用绑定路径，就像ProjectID您的 Project 类具有 property 一样ID。ProjectName和属性也是如此Name。

E：当您遇到绑定问题时，在 Visual Studio 的调试模式下查看Output选项卡以查看数据绑定引擎返回了哪些错误非常有用。这些异常通常不会返回给用户，但您可以在那里检查它们。
