如何重构linq ..？ [英] How to refactor in linq..?

问题描述

public List<carlistviewmodel> GetFilter(List<string> HondaCustomer, List<carlistviewmodel> CarList)
        {
            List<carlistviewmodel> List = new List<carlistviewmodel>();
            
                foreach (string Hcustomer in HondaCustomer)
                {
                    foreach (CarListViewModel detail in CarList)
                    {
                        if (detail.CustomerName == Hcustomer)
                        {
                            List.Add(detail);

                        }
                    }
                }
            

            return List;
        }

我的尝试：

What I have tried:

public List<carlistviewmodel> GetFilter(List<string> HondaCustomer, List<carlistviewmodel> CarList)
        {
            List<carlistviewmodel> List = new List<carlistviewmodel>();
            
                foreach (string Hcustomer in HondaCustomer)
                {
                    foreach (CarListViewModel detail in CarList)
                    {
                        if (detail.CustomerName == Hcustomer)
                        {
                            List.Add(detail);

                        }
                    }
                }
            

            return List;
        }

推荐答案

如果我理解正确的问题，我认为您正在寻找：

If I understand the question correctly I think you are looking for:

List<carlistviewmodel> List = CarList.Where(detail => HondaCustomer.Contains(detail.CustomerName)).toList();
