C# Winform实现五子棋游戏（代完善）

实现了基本的玩法。

BoardController.cs

using System;namespace GomokuGame
{public class BoardController{private static BoardController instance;private readonly int[,] board;private const int boardSize = 15;private BoardController(){board = new int[boardSize, boardSize];}public static BoardController Instance{get{if (instance == null){instance = new BoardController();}return instance;}}public int[,] GetBoard() => board;public bool PlacePiece(int x, int y, int player){if (board[x, y] == 0){board[x, y] = player;return true;}return false;}public bool CheckWin(int player){for (int i = 0; i < boardSize; i++){for (int j = 0; j < boardSize; j++){if (board[i, j] == player){if (CheckDirection(i, j, 1, 0, player) || // HorizontalCheckDirection(i, j, 0, 1, player) || // VerticalCheckDirection(i, j, 1, 1, player) || // Diagonal \CheckDirection(i, j, 1, -1, player))  // Diagonal /{return true;}}}}return false;}private bool CheckDirection(int startX, int startY, int dx, int dy, int player){int count = 0;for (int i = 0; i < 5; i++){int x = startX + i * dx;int y = startY + i * dy;if (x >= 0 && x < boardSize && y >= 0 && y < boardSize && board[x, y] == player){count++;}else{break;}}return count == 5;}}
}

BoardView.cs

using System;
using System.Drawing;
using System.Windows.Forms;namespace GomokuGame
{public class BoardView : Panel{private const int cellSize = 30;private const int boardSize = 15;private int[,] board;private int currentPlayer;public BoardView(){this.DoubleBuffered = true;this.Size = new Size(boardSize * cellSize, boardSize * cellSize);board = BoardController.Instance.GetBoard();currentPlayer = 1;this.Paint += BoardView_Paint;this.MouseClick += BoardView_MouseClick;}private void BoardView_Paint(object sender, PaintEventArgs e){Graphics g = e.Graphics;for (int i = 0; i < boardSize; i++){for (int j = 0; j < boardSize; j++){g.DrawRectangle(Pens.Black, i * cellSize, j * cellSize, cellSize, cellSize);if (board[i, j] == 1){g.FillEllipse(Brushes.Black, i * cellSize, j * cellSize, cellSize, cellSize);}else if (board[i, j] == 2){g.FillEllipse(Brushes.Black, i * cellSize, j * cellSize, cellSize, cellSize);g.FillEllipse(Brushes.White, i * cellSize + 2, j * cellSize + 2, cellSize - 4, cellSize - 4);}}}}private void BoardView_MouseClick(object sender, MouseEventArgs e){int x = e.X / cellSize;int y = e.Y / cellSize;if (BoardController.Instance.PlacePiece(x, y, currentPlayer)){this.Invalidate();if (BoardController.Instance.CheckWin(currentPlayer)){MessageBox.Show($"Player {currentPlayer} wins!");}// 交换玩家currentPlayer = currentPlayer == 1 ? 2 : 1;}}}
}

Form1.cs

using System;
using System.Windows.Forms;namespace GomokuGame
{public partial class Form1 : Form{public Form1(){InitializeComponent();InitializeGame();}private void InitializeGame(){BoardView boardView = new BoardView();boardView.Dock = DockStyle.Fill;this.Controls.Add(boardView);IGameStrategy strategy = new PvPStrategy();strategy.Execute();}}
}

Form1.Designer.cs

using System;
using System.Windows.Forms;namespace GomokuGame
{partial class Form1 :  Form{private System.ComponentModel.IContainer components = null;protected override void Dispose(bool disposing){if (disposing && (components != null)){components.Dispose();}base.Dispose(disposing);}private void InitializeComponent(){this.SuspendLayout();// // Form1// this.ClientSize = new System.Drawing.Size(800, 450);this.Name = "Form1";this.ResumeLayout(false);}}
}

GameStrategy.cs

using System;public interface IGameStrategy
{void Execute();
}public class PvPStrategy : IGameStrategy
{public void Execute(){Console.WriteLine("Player vs Player mode.");}
}public class PvAIStrategy : IGameStrategy
{public void Execute(){Console.WriteLine("Player vs AI mode.");}
}

PieceFactory.cs

using System;public abstract class Piece
{public abstract void Place(int x, int y);
}public class BlackPiece : Piece
{public override void Place(int x, int y){Console.WriteLine($"Placed black piece at ({x}, {y})");}
}public class WhitePiece : Piece
{public override void Place(int x, int y){Console.WriteLine($"Placed white piece at ({x}, {y})");}
}public class PieceFactory
{public static Piece CreatePiece(int player){return player == 1 ? new BlackPiece() : (Piece)new WhitePiece();}
}

PlacePieceCommand.cs

using GomokuGame;
public interface ICommand
{void Execute();
}public class PlacePieceCommand : ICommand
{private readonly int x;private readonly int y;private readonly int player;public PlacePieceCommand(int x, int y, int player){this.x = x;this.y = y;this.player = player;}public void Execute(){BoardController.Instance.PlacePiece(x, y, player);PieceFactory.CreatePiece(player).Place(x, y);}
}

Program.cs

using System;
using System.Windows.Forms;namespace GomokuGame
{static class Program{[STAThread]static void Main(){Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);Application.Run(new Form1());}}
}
