使用实体框架 6 返回具有最大列值的记录

试图获得最大记录datetime价值ReceivedDateTime列，但是数据集应该经过一些预先过滤Id列（不是唯一的）。是这样解决的：

using (var db = new SystemEntities())
{
    var records = db.Table.Where(p => p.Id == Id);
    var record = records.Where(p => p.ReceivedDateTime == records.Max(r => r.ReceivedDateTime)).FirstOrDefault();
    if(record != null)
    {

    }
}

有没有更漂亮、更简单、更短的实现、符号？谢谢！

您可以像下面这样简化使用OrderByDescending:

using (var db = new SystemEntities())
{
    var record = db.Table.Where(p => p.Id == Id).OrderByDescending(x => x.ReceivedDateTime).FirstOrDefault();
    if(record != null){}
}
