WPF笔记（三）MVVM

一个简单的小例子，用来复习刚学的MVVM

项目结构



Model.BuyMessage代码

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

namespace wpftest.Model
{
public  class BuyMessage
{
public int quantity
{
get;
set;
}

public string name
{
get;
set;
}

public string rate
{
get;
set;
}
}
}

ViewModel.MainViewModel代码

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

namespace wpftest.ViewModel
{
public class MainViewModel
{
public MainViewModel() {
this.buyMessages = new ObservableCollection<Model.BuyMessage>();

this.buyMessages.Add(new Model.BuyMessage
{
quantity = 100,
name="likai",
rate="AA-"

});

}

public ObservableCollection<Model.BuyMessage> buyMessages
{
get;
set;

}
}
}

MainWindow.xaml

<Window x:Class="wpftest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>

</Grid.RowDefinitions>

<DataGrid Grid.Row="0" ItemsSource="{Binding buyMessages}" CanUserAddRows="False" AutoGenerateColumns="False">
<DataGrid.Columns >
<DataGridTextColumn Width="220" Header="quantity" Binding="{Binding quantity}"></DataGridTextColumn>
<DataGridTextColumn Width="220" Header="name" Binding="{Binding name}"></DataGridTextColumn>
<DataGridTextColumn Width="220" Header="rate" Binding="{Binding rate}"></DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
</Grid>
</Window>

运行结果



刚学没多久，徒手写这个小例子，权当温习一下
