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.... Belts Tshirt Trousers Footwear Electronics
