第一步：数据库部署
- 在SQL Server中执行完整的SQL脚本
- 脚本会自动创建数据库、表、存储过程和定时作业
- 检查数据库部署是否成功：查看输出窗口中的提示信息
第二步：C#项目配置
- 创建新的C# WinForms项目
- 添加上述所有C#文件到项目中
- 添加必要的引用：
- System.Configuration
- System.Data.SqlClient
- 修改连接字符串（如果需要）
第三步：运行应用程序
- 编译并运行程序
- 主界面包含三个标签页：
- 清理配置：管理清理策略
- 清理历史：查看执行记录
- 系统设置：配置连接和作业
第四步：基本使用流程
- 添加配置：点击"添加配置"按钮，设置清理策略
- 执行清理：选择配置，点击"执行清理"按钮
- 查看结果：在历史记录中查看清理详情
- 定时任务：在系统设置中管理SQL Server代理作业
🔧 常见问题解决方案
问题1：连接数据库失败
解决方案：
- 检查SQL Server服务是否启动
- 验证连接字符串是否正确
- 确认登录账号有访问权限
- 检查防火墙设置
问题2：清理速度太慢
优化建议：
- 增大批处理大小（修改配置中的BatchSize）
- 减少批处理延迟（修改BatchDelay）
- 在目标表上创建合适的索引
- 避免在业务高峰期执行
问题3：作业执行失败
排查步骤：
- 检查SQL Server代理是否启用
- 查看作业历史记录
- 验证存储过程权限
- 检查数据库连接
