MVC中linq分组问题，我想按照姓名分组
public ActionResult Item()
{
var linq = from c in db.Companys
from d in db.Departments
from b in db.Brokers
where c.CompanyId == d.CompanyId
where d.DeptId == b.DeptId
orderby c.CompanyName
select new vmodel
{
ComId = c.CompanyId, //公司ID
ComName = c.CompanyName, //公司名称
DeptComId = d.CompanyId, //部门所属的公司ID
DeptId = d.DeptId, //部门ID
DeptName = d.IH_Name, //部门名称
BrokerDeptId = b.DeptId, //经纪人所属部门ID
BrokerId = b.UserId, //经纪人ID
BrokerName = b.RealName
}.ComName.GroupBy(c.CompanyId);
return View(linq);
}
我现在数据是这样的

我想把重复的去掉
[最优解释]
什么叫“重复的”。

如果是每个人保留一条的话

var result = data.GroupBy(x => x.姓名).Select(x => x.First());
