wpf 分别用前台和后台 两种方法 绘制矩形 填充

 

xaml：

<Window x:Class="WpfApplication1.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">    <UniformGrid x:Name="CheckeBoard">        <!--<Rectangle Fill="Black"/>        <Rectangle Fill="White" />        <Rectangle Fill="White" />        <Rectangle Fill="Black"/>-->    </UniformGrid></Window>

 

 

后台：

using System;using System.Collections.Generic;using System.Linq;using System.Text;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 WpfApplication1{    /// <summary>    /// MainWindow.xaml 的交互逻辑    /// </summary>    public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();            CheckeBoard.Rows = 7;            CheckeBoard.Columns = 7;            for (int i = 0; i <= 24; i++) {                CheckeBoard.Children.Add(new Rectangle() { Fill = Brushes.Black });                CheckeBoard.Children.Add(new Rectangle() { Fill = Brushes.White });            }        }    }}
