グラフィックを含むクラスをグリッドのクラスに追加するにはどうすればよいですか? 現在、 CreateGraphicsにエラーがあります。
using System.Windows;
using System.Windows.Controls;
namespace Othello
{
class Board : Grid
{
public Grid grid = new Grid();
ColumnDefinition col;
RowDefinition row;
int boxesAmount = 8;
int boxSize = 100;
int i = 0;
public Board()
{
grid.Width = boxSize * boxesAmount;
grid.Height = boxSize * boxesAmount;
grid.HorizontalAlignment = HorizontalAlignment.Left;
grid.VerticalAlignment = VerticalAlignment.Top;
grid.ShowGridLines = true;
grid.Background = System.Windows.Media.Brushes.Green;
for (i = 0; i < boxesAmount; i++)
{
// Create Columns
col = new ColumnDefinition();
grid.ColumnDefinitions.Add(col);
// Create Rows
row = new RowDefinition();
grid.RowDefinitions.Add(row);
}
//Console.WriteLine(grid));
this.Children.Add(grid);
Chess chess = new Chess();
grid.Children.Add(chess);
Grid.SetColumn(chess, 0);
Grid.SetRow(chess, 0);
}
}
}
グラフィックを含む 2 番目のクラス
using System;
using System.Drawing;
using System.Windows.Controls;
namespace Othello
{
class Chess : UserControl
{
Graphics g;
public Chess()
{
Console.WriteLine("load chess");
g = this.CreateGraphics();
g.DrawEllipse(Pens.Black, 30, 30, 50, 50);
this.AddChild(g);
}
}
}

error CS1061: 'Othello.Chess' does not contain a definition for 'CreateGraphics' and no extension method 'CreateGraphics' accepting a first argument of type 'Othello.Chess' could be found (are you missing a using directive or an assembly reference?)
