[英]How to aggregate the value from DISTINCT row using LINQ
I have following data: 我有以下数据:
Name Priority
A 3
A 5
B 1
C 1
C 3
C 2
I want to get list of distinct names with All priority, so the result 我想获得具有所有优先级的不同名称的列表,因此结果
would look like: 看起来像:
Name priorities
A 3,5
B 1
C 1,3,2
How can I use Linq to do that? 我如何使用Linq来做到这一点?
Use this overload of GroupBy 使用GroupBy的这个重载
var grouped = myList.GroupBy(i => i.Name, i => i.Priority,
(Name, Priorities) => new {Name, Priorities});
