C#中DataGrid的數據Binding的使用

WPF中提供xaml文件跟後臺的C#代碼數據交換的一種新的方式，那就是Binding。流程如下：

1、定義相應的類

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace WpfApp1
{
    class student
    {
        public string name { get; set; }
        public string ID { get; set; }
    }
}

2、在xaml文件中Binding相應的屬性，代碼中的name，ID均爲類中的屬性值

<Window x:Class="WpfApp1.Window2"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApp1"
        mc:Ignorable="d"
        Title="Window2" Height="450" Width="800">
    <Grid>
        <StackPanel Margin="5" Orientation="Horizontal">
            <DataGrid Name="datagrid" AutoGenerateColumns="False" CanUserAddRows="False">
                <DataGrid.Columns>
                    <DataGridTextColumn Header="Name" MinWidth="60" Binding="{Binding name}"/>
                    <DataGridTextColumn Header="age" MinWidth="60" Binding="{Binding ID}"/>
                </DataGrid.Columns>
            </DataGrid>
            <Button Name="button1" Content="ok" VerticalAlignment="Top" Margin="5" Click="Button1_Click"/>
        </StackPanel>
        
    </Grid>
</Window>

3、在後臺的C#代碼中定義動態集合，指明Binding的源，增加數據到DataGrid中

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.Shapes;
using System.Collections.ObjectModel;

namespace WpfApp1
{
    /// <summary>
    /// Window2.xaml 的交互邏輯
    /// </summary>
    public partial class Window2 : Window
    {
        ObservableCollection<student> studentlist = new ObservableCollection<student>();
        public Window2()
        {
            InitializeComponent();
            datagrid.ItemsSource = studentlist;  //將datagrid的源Binding到studentlist
        }

        private void Button1_Click(object sender, RoutedEventArgs e)
        {
            Random rd = new Random();
            studentlist.Add(new student()  //增加datagrid數據
            {
                name = "chris",
                ID = Convert.ToString(rd.Next(1000, 2000)),
            });
        }
    }
}
