1：控制台

using ScreenFile.Script;using System;using System.Collections.Generic;namespace ScreenFile{    class Program    {        public static FileUtil fileUtil;        public static Command command;        public static ScreenText screen;        private static string inputValue;                private static void Main(string[] args)        {            fileUtil = new FileUtil();            command = new Command();            screen = new ScreenText();                        while (inputValue != "Close")            {                inputValue = Console.ReadLine();                if (command.Check(inputValue))                {                    Do_Command();                }                else if (screen.Check(inputValue))                {                    Do_ScreenText();                }            }        }        private static void Do_Command()        {            command.ExecutiveCommand(inputValue);        }        private static void Do_ScreenText()        {            List
       
         temp = screen.GetResult(inputValue);            for (int i = 0; i < temp.Count; i++)            {                Console.WriteLine(temp[i]);            }        }        public static void Do_Screen(string content)        {            if (screen.Check(content))            {                List
        
          temp = screen.GetResult(content);                for (int i = 0; i < temp.Count; i++)                {                    Console.WriteLine(temp[i]);                }            }        }    }}
        
       

2：命令管理

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Text.RegularExpressions;using System.Threading.Tasks;namespace ScreenFile.Script{    class Command    {        private Regex regex;        public Command()        {            regex = new Regex("^@.*");        }        public bool Check(string command)        {            return regex.IsMatch(command);        }        public void ExecutiveCommand(string command)        {            command = regex.Match(command).Value.Trim();            string[] cmds = command.Split(':');            switch (cmds[0])            {                case "@Key":                    Program.screen.ChangeRegex(cmds[1], cmds[2]);                    break;                case "@End":                    Program.screen.suffixName = cmds[1] == "true";                    break;                case "@File":                    string content = Program.fileUtil.Get_FileContent(cmds[1]);                    Program.Do_Screen(content);                    break;                default:                    break;            }        }    }}

3：读取本地文本

using System.IO;namespace ScreenFile.Script{    class FileUtil    {        public string Get_FileContent(string path)        {            using (FileStream fs = new FileStream(path, FileMode.OpenOrCreate))            {                StreamReader sr = new StreamReader(fs);                string content = sr.ReadToEnd();                sr.Close();                return content;            }        }    }}

4：正则匹配

using System.Collections.Generic;using System.Text.RegularExpressions;namespace ScreenFile.Script{    class ScreenText    {        public string key_start = "https://";        public string key_end = ".html";        public bool suffixName;        private Regex regex;        private List
      
        result;        public ScreenText()        {            string match = string.Format("(?<={0}).*?(?={1})", key_start, key_end);            regex = new Regex(match);            result = new List
       
        ();        }        public void ChangeRegex(string start, string end)        {            if (!string.IsNullOrEmpty(start))                key_start = start;            if (!string.IsNullOrEmpty(end))                key_end = end;            string match = string.Format("(?<={0}).*?(?={1})", key_start, key_end);            regex = new Regex(match);        }        public bool Check(string infomation)        {            return regex.IsMatch(infomation);        }        public List
        
          GetResult(string infomation)        {            result.Clear();            foreach (Match mch in regex.Matches(infomation))            {                if (suffixName)                {                    result.Add(mch.Value.Trim() + key_end);                }                else                {                    result.Add(mch.Value.Trim());                }            }            return result;        }    }}
