Question

请你指点一个好的C＃教程，使用WPF在Canvas上绘制像Ellipse和Rectangle（继承自Shape）的2D图形？我以后也有兴趣点击形状并识别被点击的形状，以及在画布上拖放形状。谢谢！

感谢您的链接。您能否告诉我，我应该在Visual Studio中启动哪个项目来编译和运行此程序（取自Shapes and Basic Drawing in WPF）：

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
using System.Windows.Shapes;

namespace SDKSample
{
    public partial class SetBackgroundColorOfShapeExample : Page
    {
        public SetBackgroundColorOfShapeExample()
        {
            // Create a StackPanel to contain the shape.
            StackPanel myStackPanel = new StackPanel();

            // Create a red Ellipse.
            Ellipse myEllipse = new Ellipse();

            // Create a SolidColorBrush with a red color to fill the 
            // Ellipse with.
            SolidColorBrush mySolidColorBrush = new SolidColorBrush();

            // Describes the brush's color using RGB values. 
            // Each value has a range of 0-255.
            mySolidColorBrush.Color = Color.FromArgb(255, 255, 255, 0);
            myEllipse.Fill = mySolidColorBrush;
            myEllipse.StrokeThickness = 2;
            myEllipse.Stroke = Brushes.Black;

            // Set the width and height of the Ellipse.
            myEllipse.Width = 200;
            myEllipse.Height = 100;

            // Add the Ellipse to the StackPanel.
            myStackPanel.Children.Add(myEllipse);

            this.Content = myStackPanel;
        }

    }
}

MSDN非常了解Shapes and Basic Drawing in WPF。
