如何使用StreamWriter将C#飞镖模拟器的运行结果写入TXT文件

修改说明 #

• 新增游戏结果导出TXT功能，使用StreamWriter写入所有玩家的每轮投掷记录、总得分、获胜者信息到文件
• 新增核心数据提取逻辑，可直接获取获胜玩家、平均每轮得分、最高单轮得分等字段
• 界面提示翻译为中文，方便使用
• 生成的TXT文件默认保存在程序exe运行同级目录下，命名为飞镖游戏结果.txt

完整可运行代码 #

                turnOne, turnTwo, turnThree, Get_Score());
        }
    }
}

效果说明 #

• 运行程序后控制台会打印所有玩家得分，同时自动生成TXT结果文件
• 如需修改保存路径，调用ExportResultToTxt时传入自定义绝对路径即可，比如ExportResultToTxt(@"C:\Users\XXX\Desktop\game_result.txt")
• 可根据需求在ExportResultToTxt方法内扩展提取更多数据字段
