C#如何对List按照某一字段进行分组

[肆年]

原有一List,定义

List<CommodityInfo> commodityInfoList = new List<CommodityInfo>();
    public class CommodityInfo
    {
        public string StoreID {get; set;}
        public string CommodityID {get; set;}
        public string CommodityName {get; set;}
        public decimal CommodityPrice {get; set;}
}

如何按照StoreID进行分组，形成如下List

List<StoreInfo> storeInfoList = new List<StoreInfo>();

    public class StoreInfo
    {
        public string StoreID {get; set;}
        public List<CommodityInfo> {get; set;}
	}

commodityInfoList.GroupBy(x => x.StoreID).Select(x => new StoreInfo { StoreID = x.Key, List = x.ToList() })

commodityInfoList.GroupBy(x => x.StoreID).Select(x => new StoreInfo { StoreID = x.Key, List = x.ToList() })

public List<CommodityInfo> {get; set;} -> public List<CommodityInfo> List {get; set;}
