如何查找可疑语句,如"Name = Name;" 在C#by Regex？

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
        string code = "Name = Name;";
        string pattern = @"\b(\w+)\s*=\s*\1\b";

        Match match = Regex.Match(code, pattern);
        if (match.Success)
        {
            Console.WriteLine("可疑语句：{0}", match.Value);
        }
        else
        {
            Console.WriteLine("未找到可疑语句。");
        }
    }
}
