关于WordCount的作业

一、开发者：201631062418

二、代码地址：https://gitee.com/YsuLIyan/WordCount

三、作业地址：https://edu.cnblogs.com/campus/xnsy/Test/homework/2203

四、基本功能

WordCount.exe -c test.txt //返回文件 test.txt的字符数

WordCount.exe -w test.txt //返回文件 test.txt的单词总数

WordCount.exe -l test.txt //返回文件 test.txt的总行数

WordCount.exe -o outputFile.txt //将结果输出到指定文件outputFile.txt

五、扩展功能

-----------------------------------------------------------------------------------------------------------------------------------------------

已经实现：-c -w -l 可以同时使用,如果没有-o命令（或者说-0之后没有接文件名），则默认outputfile.txt作为输出结果的文件（strPath）。并且扫描-0命令之后的接收结果文件名称，如果接收结果文件在该目标文件夹中不存在，则会报路径错误

-----------------------------------------------------------------------------------------------------------------------------------------------

还未实现：接收结果文件在目标文件夹中不存在时，重新创建一个名为（strPath）的接收结果文件--待后期改善。

　　　　　在命令读取时，程序对于用户输入的命令进行理解、更多的应答以及合适的补充。

-----------------------------------------------------------------------------------------------------------------------------------------------

六、项目的实现

这是一个专门处理命令的方法类，这也是我比较在意的地方，因为我很注重我写的程序对用户输入的参数的应答。

    class CommandRead
    {
        bool isRows = false;
        bool isChara = false;
        bool isWord = false;
        bool isAimPath = false;
        string[] path = new string[4];
        string[] commands;

        public bool IsRows
        {
            get { return isRows; }
        }
        public bool IsChara
        {
            get { return isChara; }
        }
        public bool IsWord
        {
            get { return isWord; }
        }
        public bool IsAimPath
        {
            get { return isAimPath; }
        }

        public string[] Path
        {
            get { return path; }
        }



        public void CommandImport(string[] args)
        {
            commands = args;
            if(commands == null)
            {
                Console.WriteLine("请输入指令");
            }
            else
            {
                int Pas = 0;

                for (int i = 0; i < commands.Length; i++)
                {
                    if (commands[i] == "-l" || commands[i] == "-L")//行数
                    {
                        isRows = true;
                    }
                    else if (commands[i] == "-w" || commands[i] == "-W")//单词
                    {
                        isWord = true;
                    }
                    else if (commands[i] == "-c" || commands[i] == "-C")//字符
                    {
                        isChara = true;
                    }
                    else if (commands[i] == "-o" || commands[i] == "-O")//输出
                    {
                        if (i + 2 == commands.Length)
                            isAimPath = true;
                    }
                    else
                    {
                        path[Pas] = commands[i];
                        Pas++;
                    }
                }
            }
        }
        
    }

这是关于读取文件行数的类

 class Rows //行数
    {
        public string ope;

        public int Line(string filename)
        {
            Encoding encod = Encoding.GetEncoding("GB2312");
            FileStream fs = new FileStream(filename, FileMode.Open);
            StreamReader sr = new StreamReader(fs, encod);

            string line;
            int CountLine = 0;//记录行数

            //当前行不为空
            while((line = sr.ReadLine()) != null)
            {
                CountLine++;
            }

            //应该先关闭文件再return
            sr.Close();
            fs.Close();

            return CountLine;//注意函数是有返回值的
        }
    }

这是读取文件符号数的类

class Word//字符
    {
        public int TotalWord(string filename)
        {
            Encoding encod = Encoding.GetEncoding("GB2312");
            FileStream fs = new FileStream(filename, FileMode.Open);
            StreamReader sr = new StreamReader(fs, encod);

            int nchar;
            int WordCount = 0;
            char[] symbol = { ' ', '\t', ',', '.', '?', '!', ':', ';', '\'', '\"', '\n', '{', '}', '(', ')', '+', '-', '*', '=' };//间隔符
            while((nchar = sr.Read())!= -1)
            {
                foreach(char c in symbol)
                {
                    if(nchar == (int)c)
                    {
                        WordCount++;
                    }
                }
            }

            sr.Close();
            fs.Close();

            return WordCount;
        }
    }

这是读取单词数的类

 class Character//单词
    {
        public string ope;

        public int TotalWord(string filename)
        {
            Encoding encod = Encoding.GetEncoding("GB2312");
            FileStream fs = new FileStream(filename, FileMode.Open);
            StreamReader sr = new StreamReader(fs, encod);

            int charcount = 0;
            int nchar;

            while((nchar = sr.Read())!= -1) //sr.Read()是以特定的编码方式读取流而获取一个接一个的字符，而ReadLine()是读取一行
            {
                charcount++; // 统计字符数
            }

            //关闭文件
            sr.Close();
            fs.Close();

            return charcount;
        }
    }

这是将得到的信息写入指定文件的方法类

class WriteFile
    {
        public void Write(string theword)
        {
            FileStream fs = new FileStream("outputfile.txt", FileMode.Create);
            //获得字节数
            byte[] data = System.Text.Encoding.Default.GetBytes(theword);

            //写入
            fs.Write(data, 0, data.Length);
            //清空缓存区，关闭流
            fs.Flush();
            fs.Close();
        }

        public void Write(string path,string theword)
        {
            bool isInFile = false;
            String rootPath = Directory.GetCurrentDirectory();
            DirectoryInfo root = new DirectoryInfo(rootPath);
            foreach(FileInfo f in root.GetFiles())
            {
                if(path == f.Name)
                {
                    isInFile = true;
                }
            }
            if (isInFile != false)
            {
                FileStream fs = new FileStream(path, FileMode.Create);
                //获得字节数
                byte[] data = System.Text.Encoding.Default.GetBytes(theword);

                //写入
                fs.Write(data, 0, data.Length);
                //清空缓存区，关闭流
                fs.Flush();
                fs.Close();
            }
            else
            {
                Console.WriteLine("Path Error!");
            }
        }
    }

然后就是主函数

class Program
    {
         
        static void Main(string[] args)
        {
            string[] cmds = args;
            string theWord = "";
            int ope1 = 0,ope2 = 0,ope3 = 0;
            for(int i =0; i<args.Length;i++)
            Console.WriteLine(args[i]);

            //新建对象读取命令
            CommandRead cmd = new CommandRead();
            cmd.CommandImport(cmds);

            if (cmd.IsRows==true)
            {
                Rows rows = new Rows();
                ope1 = rows.Line(cmd.Path[0]);
                Console.WriteLine("Total Line:{0}", ope1);
                theWord += string.Format("Total Line:{0}\r\n", ope1);
            }
            if (cmd.IsChara==true)
            {
                Character ch = new Character();
                ope2 = ch.TotalWord(cmd.Path[0]);
                Console.WriteLine("Total Character:{0}", ope2);
                theWord += string.Format("Total Character:{0}\r\n", ope2);
            }
            if (cmd.IsWord==true)
            {
                Word word = new Word();
                ope2 = word.TotalWord(cmd.Path[0]);
                Console.WriteLine("Total Word:{0}", ope3);
                theWord += string.Format("Total Word:{0}\r\n", ope3);
            }
            WriteFile write = new WriteFile();
            if (cmd.IsAimPath)
            {
                write.Write(cmd.Path[1], theWord);
            }
            if(cmd.IsAimPath == false)
            {
                write.Write(theWord);
            }

        }
    }
