## 主要改进 - 实现 /api/status/model 接口，返回真实PDMS模型状态信息 - 使用MDB.CurrentMDB、Project.CurrentProject等AVEVA API获取真实数据 - 移除硬编码的CurrentSession、PositionInfo、PdmsSpecific等复杂结构 - 简化数据模型，只保留核心的真实数据字段 ## 技术实现 - 通过DbSession获取真实的用户名、会话开始时间和持续时间 - 通过WorldMembers()获取真实的模型元素统计 - 修复DateTime类型的null合并运算符编译错误 - 清理不使用的方法和类定义 ## API返回数据 现在返回的数据主要包含真实的PDMS信息： - ModelLoaded: MDB连接状态检查 - ProjectName: 真实的设计数据库名称 - MdsName: 真实的MDB名称 - UserName: 真实的数据库会话用户 - StartTime: 真实的会话创建时间 - TotalElements: 真实的模型元素数量统计 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

<p> Class to define comparers for ordering lists of attributes. These allow lists of attributes to be sorted on the value of any field. At present, only an alphabetic sort on field values expressed as strings is implemented, although it would be possible to extend this to sort on numerical values. However, as most integers actually represent hash values or enumerations, this may be less useful than it at first sounds! </p>
