如何在C#中使用Regex检索所选文本？

using System.Text.RegularExpressions;

Regex regex = new Regex(@"\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b");

MatchCollection matches = regex.Matches(input);

foreach (Match match in matches)
{
    Console.WriteLine(match.Value);
}

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main(string[] args)
    {
        // 创建正则表达式对象并提供匹配模式
        Regex regex = new Regex(@"\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b");

        // 要搜索的文本
        string input = "Please contact support@example.com for assistance.";

        // 在文本中查找所有匹配项
        MatchCollection matches = regex.Matches(input);

        // 输出所有匹配项的值
        foreach (Match match in matches)
        {
            Console.WriteLine(match.Value);
        }
    }
}
