在C#中,可以使用LINQ的Intersect方法来处理嵌套集合的交集问题。下面是一个示例代码:
using System; using System.Collections.Generic; using System.Linq; class Program { static void Main() { List> nestedList1 = new List
> { new List
{1, 2, 3}, new List {2, 3, 4}, new List {3, 4, 5} }; List > nestedList2 = new List
> { new List
{2, 3, 4}, new List {3, 4, 5}, new List {4, 5, 6} }; var intersection = nestedList1.SelectMany(x => x) .Intersect(nestedList2.SelectMany(y => y)) .ToList(); foreach (var item in intersection) { Console.WriteLine(item); } } }
在这个示例中,我们有两个嵌套的List>,分别是nestedList1和nestedList2。我们通过SelectMany方法将它们转换成一个一维的List
