连接两个List

需要使用ToList方法将concat 的结果转化为List

 

 

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

class Program
{
    static void Main()
    {
	List list1 = new List();
	list1.Add("dot");
	list1.Add("net");

	List list2 = new List();
	list2.Add("perls");
	list2.Add("!");

	var result = list1.Concat(list2);
	List resultList = result.ToList();
	foreach (var entry in resultList)
	{
	    Console.WriteLine(entry);
	}
    }
}
