如何在C#中联接或串联两个列表？

要串联两个列表，请使用AddRange()方法。

设置第一个列表-

var products1 = new List < string > ();
products1.Add("Belts");
products1.Add("Tshirt");
products1.Add("Trousers");

设置第二个列表-

var products2 = new List < string > ();
products2.Add("Footwear");
products2.Add("Electronics");

要连接两个列表-

products1.AddRange(products2);

以下是完整的代码-

示例

using System.Collections.Generic;
using System;

namespace Demo {
   public static class Program {
      public static void Main() {
         var products1 = new List < string > ();
         products1.Add("Belts");
         products1.Add("Tshirt");
         products1.Add("Trousers");

         Console.WriteLine("Our list1....");
         foreach(var p in products1) {
            Console.WriteLine(p);
         }

         var products2 = new List < string > ();
         products2.Add("Footwear");
         products2.Add("Electronics");

         Console.WriteLine("Our list2....");
         foreach(var p in products2) {
            Console.WriteLine(p);
         }
         products1.AddRange(products2);
         Console.WriteLine("Concatenated list....");
         foreach(var p in products1) {
            Console.WriteLine(p);
         }
      }
   }
}

输出结果

Our list1....
Belts
Tshirt
Trousers
Our list2....
Footwear
Electronics
Concatenated list....
