WPF 子选项为CheckBox的TreeView

在WPF实际项目开发的时候，经常会用到带CheckBox的TreeView，虽然微软在WPF的TreeView中没有提供该功能，但是微软在WPF中提供强大的ItemTemplate模板功能和自定义样式，那我们可以自己写一个这样的控件供自己使用。

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Windows;

namespace TreeViewWithCheckBoxes
{
    /// 

    /// Interaction logic for App.xaml
    /// 

    public partial class App : Application
    {
    }
}
