从条件父id和子id linq C#的列表中删除

var itemsToDelete = itemList.Where(item => item.ParentId == parentId && item.ChildId == childId).ToList();

itemsToDelete.ForEach(item => itemList.Remove(item));

using System;
using System.Collections.Generic;
using System.Linq;

public class Item
{
    public int ParentId { get; set; }
    public int ChildId { get; set; }
    // 其他属性...
}

public class Program
{
    public static void Main()
    {
        // 假设有一个包含项的列表
        var itemList = new List<Item>
        {
            new Item { ParentId = 1, ChildId = 1 },
            new Item { ParentId = 1, ChildId = 2 },
            new Item { ParentId = 2, ChildId = 1 },
            new Item { ParentId = 2, ChildId = 2 }
        };

        int parentId = 1;
        int childId = 2;

        // 根据条件父id和子id筛选出要删除的项
        var itemsToDelete = itemList.Where(item => item.ParentId == parentId && item.ChildId == childId).ToList();

        // 从原始列表中移除要删除的项
        itemsToDelete.ForEach(item => itemList.Remove(item));

        // 输出修改后的列表
        foreach (var item in itemList)
        {
            Console.WriteLine($"ParentId: {item.ParentId}, ChildId: {item.ChildId}");
        }
    }
