C# Linq запрос к группам по группам, а затем подгруппа

Question

Вопрос: У меня есть список элементов, которые мне нужны для первой группы, а затем подгруппы по количеству элементов в вашей группе продуктов. Код ниже. Цель состоит в том, чтобы создать соответствующие группы, в которых зоны и продукты доступны в каждом матче. Зона и продукт могут быть изменены, но количество доступных продуктов всегда должно быть сгруппировано.

например. учитывая ниже ...

Результат должен быть ...

Group 1 
Zone = "EAST", Product = "Bananas", ShippingTime = "3_Days" }; 
Zone = "EAST", Product = "Oranges", ShippingTime = "5_Days" }; 
Zone = "SOUTH", Product = "Bananas", ShippingTime = "3_Days" }; 
Zone = "SOUTH", Product = "Oranges", ShippingTime = "10_Days" }; 

Группа 2

Zone = "WEST", Product = "Oranges", ShippingTime = "3_Days" }; 
Zone = "WEST", Product = "Oranges", ShippingTime = "5_Days" }; 
Zone = "WEST", Product = "Oranges", ShippingTime = "10_Days" }; 
Zone = "WEST", Product = "Apples", ShippingTime = "3_Days" }; 
Zone = "WEST", Product = "Apples", ShippingTime = "5_Days" }; 
Zone = "WEST", Product = "Apples", ShippingTime = "5_Days" }; 
Zone = "WEST", Product = "Bananas", ShippingTime = "3_Days" }; 
Zone = "WEST", Product = "Bananas", ShippingTime = "5_Days" }; 
Zone = "WEST", Product = "Bananas", ShippingTime = "5_Days" }; 

Идеальная группировка будет вспыхивать ниже из группы 2 (CAUS' они совпадают то, что в 1-й группе) и добавить к 1-й группе, в результате чего остаточная в группе 2.

Zone = "WEST", Product = "Bananas", ShippingTime = "3_Days" }; 
Zone = "WEST", Product = "Oranges", ShippingTime = "10_Days" }; 

Вот тест, с которым я работал. Ничто из того, что я мог сделать с linq, похоже, не выполнило свою работу. Спасибо, что за идеи.

Answer 1

Я не уверен, что понял вас правильно, но я думаю, что вы хотите сделать что-то вроде этого:

myList.Select(record => record.Product) 
     .Distinct() 
     .Select(p => new 
       { 
        Product = p, 
        Zones = myList.Where(r => r.Product == p) 
           .Select(r => r.Zone) 
           .Distinct() 
       }) 
     .GroupBy(an => an.Zones.Count())
