C#控制台应用程序，从两个文本文件中搜索匹配的string[]

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string[] file1Lines = File.ReadAllLines("file1.txt");
        string[] file2Lines = File.ReadAllLines("file2.txt");

        // 在这里进行匹配操作
        // ...

        Console.WriteLine("匹配的结果:");
        // 输出匹配结果
        // ...
    }
}

using System;
using System.IO;
using System.Linq;

class Program
{
    static void Main()
    {
        string[] file1Lines = File.ReadAllLines("file1.txt");
        string[] file2Lines = File.ReadAllLines("file2.txt");

        string[] matchedStrings = file1Lines.Intersect(file2Lines).ToArray();

        Console.WriteLine("匹配的结果:");
        foreach (string matchedString in matchedStrings)
        {
            Console.WriteLine(matchedString);
        }
    }
