C# - WPF -绑定要在StatusBar中打印的List<int>？

<StatusBar>
    <TextBlock Text="{Binding Path=IntList}" />
</StatusBar>

private List<int> intList;
public List<int> IntList
{
    get { return intList; }
    set
    {
        intList = value;
        OnPropertyChanged("IntList");
    }
}

public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged(string propertyName)
{
    PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}

public MainWindow()
{
    InitializeComponent();
    IntList = new List<int> { 1, 2, 3, 4, 5 };
    DataContext = this;
}
