我在员工和团队之间有很多很多关系.遵循linq声明

int[] GroupIDs = {6,7};


var result = from g in umGroups
    join empGroup in umEmployeeGroups on g.GroupID equals empGroup.GroupID
    where  GroupIDs.Contains(g.GroupID)                     
    select new {  GrpId = g.GroupID,EmployeeID = empGroup.EmployeeID };

返回groupid和employeeid.结果是

GrpId  | EmployeeID
6      |   18
6      |   20  
7      |   19
7      |   20

我需要删除employeeid重复的行,例如employeeid = 20中的任何一行
谢谢

我有一个具有属性的对象列表,可用于将对象分成对.我事先知道每个物体都是一对的一部分.

这是一个说明情况的例子:

假设我的清单如下:

List<Shoe> shoes = new List<Shoe>();

shoes.Add(new Shoe { Id = 19, Brand = "Nike", LeftOrRight = LeftOrRight.L });
shoes.Add(new Shoe { Id = 29, Brand = "Nike", LeftOrRight = LeftOrRight.R });
shoes.Add(new Shoe { Id = 11, Brand = "Nike", LeftOrRight = LeftOrRight.L });
shoes.Add(new Shoe { Id = 60, Brand = "Nike", LeftOrRight = LeftOrRight.R });
shoes.Add(new Shoe { Id = 65, Brand = "Asics", LeftOrRight = LeftOrRight.L });
shoes.Add(new Shoe { Id = 82, …
