如何为Windows Phone 8.1（C＃）绑定到usercontrol.resources中的复杂对象

Question

I have searched the web for the last few days but can't seem to find something that I would have thought was quite a simple task. I would like to add a resource in my XAML page of my windows phone application which will reference a complex object but I can't find the correct method. Is this possible? Object is made up something similar to:

Public class ComplexClass
{
  Public string name { get; set; }
  Public int ID { get; set; }

  Public observablecollection<SimpleClass> simpleObjects { get; set; }

  Public addSimpleObject(SimpleClass newSimpleObject)
  {
    if (simpleObjects == null)
      simpleObjects = new ObservableCollection<SimpleClass>();

    simpleObjects.Add(newSimpleObject);
  }
}

Public Class SimpleClass
{
  Public String Name { get; set; }
  Public String Disc { get; set; }
}

You could use MVVM do achieve this. There are already heaps of tutorials available that you can access to show you how to follow this design pattern, so I won't go into that.

Instead I'll just show you a simple way of getting the data to your view.

In the constructor of your UserControl (or Page or whatever), set up the DataContext to an instance of your ComplexClass:

ComplexClass complexClass;

public MyUserControl1()
{
    complexClass = new ComplexClass();
    complexClass.AddSimpleObject(new SimpleClass { Name = "Bob" });
    this.DataContext = complexClass;

    this.InitializeComponent();
}

Then in your XAML you can bind to it like this:

<StackPanel>
    <!-- Binding to properties on ComplexClass -->
    <TextBlock Text="{Binding Name}" />
    <TextBlock Text="{Binding ID}" />

    <ListView ItemsSource="{Binding SimpleObjects}">
        <ListView.ItemTemplate>
            <DataTemplate>
                <StackPanel>
                    <!-- Binding to properties on SimpleClass -->
                    <TextBlock Text="{Binding Name}" />
                    <TextBlock Text="{Binding Disc}" />
                </StackPanel>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</StackPanel>

Without knowing specifics of your code, it's hard for me to suggest a method that is most suitable for you. I'd read up on MVVM and view models.
