[WPF]DataContext结果不显示

namespace DataContext_ItemSource_Demo
{
    public class Person
    {
        public string Name;
    }
    public class ViewModel
    {
        public MainWindow win;
        public Person person;
        public ViewModel(MainWindow window)
        {
            this.win = window;
            var per = new Person()
            {
                Name = "success"
            };
            win.DataContext = per;
        }
    }
}

 <Grid>
        <TextBlock
            Text="{Binding Name}"></TextBlock>
    </Grid>

发现success并没有显示：

后面发现绑定的类属性必须带上set和get，否则不会展示结果，修改之后如下：

 public class Person
 {
     public string Name { get; set; }
 }

效果：
