我有一个linq查询:
var leaveDetails = (from l in leaveList
group l by new {l.LeaveDateStart.Year, l.LeaveType}
into yearGroup
select new
{
yearGroup.Key.Year,
yearGroup.Key.LeaveType,
LeaveTaken = yearGroup.Sum(l => EntityFunctions.DiffDays(l.LeaveDateStart, l.LeaveDateEnd))
}).ToList();
结果如下所示:
但是我想分开一年。因此,对于每个独特的年份,我都会列出休假类型和休假日期。
我试过在javascript的前端做这件事,但看起来很乱。有没有办法可以在C#或linq查询中执行此操作。感谢

您有一个按年份和假类型分组的当前结果。您可以简单地按年度对当前结果进行分组,并选择保留类型和保留为每组值。
像这样(注意:尚未测试过):
var leaveDetailsPerYear = (from l in leaveDetails
group l by l.Year
into yearGroup
select new {
Year = yearGroup.Key,
Data = yearGroup.ToList()
}
)
.ToList();
