WPF将组合框绑定到业务对象的数组/列表

我正在构建一个WPF应用程序,我的UI由组合框和大约十几个其他UI控件组成.我有一个业务对象类,包含十几个属性并实现INotifyPropertyChanged.

这是我的业务对象的片段:

public class MyBusinessObject : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, e);
        }
    }

    private int _idNumber;
    public int IdNumber
    {
        get { return _idNumber; }
        set
        {
            if (_idNumber == value)
            {
                return;
            }

            _idNumber = value;
            OnPropertyChanged(new PropertyChangedEventArgs("IdNumber"));
        }
    }

    private string _name;
    public string Name
    {
        get { return _name; }
        set
        {
            if (_name == value)
            {
                return;
            }

            _name = value;
            OnPropertyChanged(new PropertyChangedEventArgs("Name"));
        }
    }

    private int _age;
    public int Age
    {
        get { return _age; }
        set
        {
            if (_age == value)
            {
                return;
            }

            _age = value;
            OnPropertyChanged(new PropertyChangedEventArgs("Age"));
        }
    }

    private string _address;
    public string Address
    {
        get { return _address; }
        set
        {
            if (_address == value)
            {
                return;
            }

            _address = value;
            OnPropertyChanged(new PropertyChangedEventArgs("Address"));
        }
    }

    private bool _employed;
    public bool Employed
    {
        get { return _employed; }
        set
        {
            if (_employed == value)
            {
                return;
            }

            _employed = value;
            OnPropertyChanged(new PropertyChangedEventArgs("Employed"));
        }
    }

    public MyBusinessObject(int idNumber)
    {
        this.IdNumber = idNumber;
        // set default values here
    }
}

正如您所料,各种UI控件将绑定到我的业务对象的属性.但是,我需要创建一个业务对象的数组或列表(其中10个是特定的)并将我的组合框绑定到IdNumber属性.因此,我的用户将从组合框中选择他们想要的对象,然后其他UI控件应更新以显示所选对象的每个绑定属性的值.

现在,我只在我的代码中声明了我的业务对象的一个​​实例,如下所示:

public partial class MainWindow : Window
{
    // this will be replaced with an array/list of business objects
    MyBusinessObject myObject = new MyBusinessObject(1234); // 1234 = IdNumber

    public MainWindow()
    {
        InitializeComponent();
        this.DataContext = myObject;
    }
}

目前,我的组合框定义如下:

一旦我实现了我的数组/业务对象列表,有人能告诉我如何将组合框绑定到数组,以便它将显示每个对象的IdNumber吗？另外,当用户在组合框中更改其选择时,我需要做什么才能使其他绑定控件反映所选对象的值？
