C#中一个简单的匹配16进制颜色的正则测试

using System;
using System.Text.RegularExpressions;

namespace Test
{
    class Program
    {
        //匹配16进制颜色代码的正则模式
        const string pattern = @"[[0-9a-fA-F]{6}]";

        const string test1 = "erter[0051e4]terter778t";
        const string test2 = "erter[+051e4]terter778t";

        static void Main(string[] args)
        {
            Regex res = new Regex(pattern);

            if (res.IsMatch(test1))
            {
                Console.WriteLine("匹配成功");
            }
            else
            {
                Console.WriteLine("匹配失败");
            }

            Console.ReadKey();
        }
    }
}
