6.4.2 Binding的数据转换

当数据从Binding的Source流向Target时，Convert方法将被调用；反之，ConvertBack方法将被调用。

        private void buttonLoad_Click(object sender, RoutedEventArgs e)        {            List<Plane> planes = new List<Plane>()             {                new Plane(){Name="J-10", Category=Plane.CategoryEnum.Fighter, State=Plane.StateEnum.Available},                new Plane(){Name="H-6", Category=Plane.CategoryEnum.Bomber, State=Plane.StateEnum.Available},                new Plane(){Name="F-22", Category=Plane.CategoryEnum.Fighter, State=Plane.StateEnum.Locked},                new Plane(){Name="B-2", Category=Plane.CategoryEnum.Bomber, State=Plane.StateEnum.UnKnown}            };            this.planeListBox.ItemsSource = planes;        }        private void buttonSave_Click(object sender, RoutedEventArgs e)        {            StringBuilder sb = new StringBuilder();            foreach (Plane p in planeListBox.Items)                sb.AppendLine(string.Format("Category={0},Name={1},State={2}", p.Category, p.Name, p.State));            File.WriteAllText(@"D:\PlaneList.txt", sb.ToString());        }

Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an excep

产生这个错误的原因是，StaticResource必须先定义再引用，但是DynamicResource就没有这个限制，为避免这个错误出现，可将StaticResource的定义放在Window.xaml的最前端，或者放在App.xaml中.
