WPF DataGrid的使用

构造数据：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApplication2
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        Random rnd = new Random();
        public MainWindow()
        {
            InitializeComponent();

           var tlist = new List<Person>();
            for (int i = 0; i < 10; i++)
            {
                tlist.Add(new Person()
                {
                    Name = "张三" + i,
                    Age = rnd.Next(20)
                });
            }
           list= tlist.Select(x => new { x, id = Guid.NewGuid() }).OrderBy(y => y.id).Select(z => z.x).ToList<Person>();
            this.DataContext = this;

        }
        public List<Person> list { get; set; }
    }
    public class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }
}

界面显示：

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="850" Width="525">

        <DataGrid Name="dg" AutoGenerateColumns="False" ItemsSource="{Binding list}" CanUserAddRows="False">
            <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding Name}" Width="100" Header="名称" />
                <DataGridTextColumn Binding="{Binding Age}" Header="年龄" />
            </DataGrid.Columns>
        </DataGrid>
        <TextBlock Text="{Binding ElementName=dg,Path=SelectedItem.Name}"></TextBlock>
