Question

我有一个这样的课程：

        void AddCustomer(Customer customer)
        {
            // Add infor of customer to dgvCustomerInfo
            int rowIndexCustomerInfo = dgvCustomerInfo.Rows.Add();
            dgvCustomerInfo.Rows[rowIndexCustomerInfo].Cells[0].Value = customer.Name;
            if (customer.Sex == true)
            {
                dgvCustomerInfo.Rows[rowIndexCustomerInfo].Cells[1].Value = "Male";
            }
            else
            {
                dgvCustomerInfo.Rows[rowIndexCustomerInfo].Cells[1].Value = "Female";
            }

            // Add favorite foof of customer to dgvFavouriteFoods
            int rowIndexFavouriteFood = dgvFavouriteFoods.Rows.Add();
            for (int i = 0; i < customer.FavouriteFoods.Count; i++)
            {
                if (i < dgvFavouriteFoods.ColumnCount)
                {
                    dgvFavouriteFoods.Rows[rowIndexFavouriteFood].Cells[i].Value = customer.FavouriteFoods[i];
                }
            }
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Customer customer1 = new Customer()
            {    
                Name ="Andrew", 
                Sex = true,
                FavouriteFoods = new List<string>(){"Pizza","Hot dog","Noodle","Chicken"
            }
            };
            Customer customer2 = new Customer()
            {
                Name = "Sandra",
                Sex = false,
                FavouriteFoods = new List<string>(){"Rice","Pork","Beef","Chicken"
            }
            };

            this.AddCustomer(customer1);
            this.AddCustomer(customer2);

        }

我有2个datagridviews： dgvCustomerInfo将显示客户的姓名和性别另外一个，dgvFavouriteFoods将展示客户最喜欢的4种食物。

These are my 2 datagridviews
我想点击dgvFavouriteFoods的任何标题，dgvFavouriteFoods将被排序，dgvCustomerInfo也将按照相应的顺序排序。
例如：
安德鲁喜欢披萨，热狗，面条，鸡肉桑德喜欢米饭，猪肉，牛肉，鸡肉当我点击dgvFavouriteFoods的标题时，dgvFavouriteFoods被排序，并且dgvCustomerInfo应该按照相应的顺序排序，让我知道
安德鲁喜欢披萨，热狗，面条，鸡肉桑德喜欢米饭，猪肉，牛肉，鸡肉。

你能帮我解决一下吗？

这是我将客户添加到这两个datagridviews的代码：

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${jackson.version}</version>
</dependency>

注意：不要更改Customer类。

您需要2个班级和1个名单：

private List<Customer> _myCustomers = new List<Customer>();

public class Customer
{
    /// <summary>  
    /// Name of customer  
    /// </summary>  
    public string Name { get; set; }

    /// <summary>  
    /// Sex of customer  
    /// </summary>  
    public bool Sex { get; set; }

    /// <summary>  
    /// List of favourite foods
    /// </summary>  
    public List<FavouriteFood> FavouriteFoods { get; set; }
}

public class FavouriteFood {
    public FavouriteFood() { }
    public FavouriteFood(string _food) { this.Food = _food; }
    public string Food { get; set; }
}

FormLoad：

private void Form1_Load(object sender, EventArgs e)
    {
        //dgvCustomerInfo grid Mouse Up Event:
        this.dgvCustomerInfo.MouseUp += new System.Windows.Forms.MouseEventHandler(this.dgvCustomerInfo_MouseUp);

        Customer customer1 = new Customer()
        {
            Name = "Andrew",
            Sex = true,
            FavouriteFoods = new List<FavouriteFood>(){
                new FavouriteFood("Pizza"),
                new FavouriteFood("Hot dog"),
                new FavouriteFood("Noodle"),
                new FavouriteFood("Chicken")
        }
        };
        Customer customer2 = new Customer()
        {
            Name = "Sandra",
            Sex = false,
            FavouriteFoods = new List<FavouriteFood>()
            {
                new FavouriteFood("Rice"),
                new FavouriteFood("Pork"),
                new FavouriteFood("Beef"),
                new FavouriteFood("Chicken")
            }
        };

        _myCustomers.Add(customer1);
        _myCustomers.Add(customer2);

        dgvCustomerInfo.DataSource = _myCustomers;
    }

上次：鼠标注册事件：

private void dgvCustomerInfo_MouseUp(object sender, MouseEventArgs e)
    {
        Customer _selected = (Customer)dgvCustomerInfo.CurrentRow.DataBoundItem;
        dgvFavouriteFoods.DataSource = _selected.FavouriteFoods;
    }

C #Windows表单：对datagridview进行排序，然后另一个datagriview将按相应的顺序排序
