WC-第二次作业

WordCount 第二次作业

码云地址：https://gitee.com/lgcj1218/WordCount/tree/master

一.解题思路

本次作业采用的c#语言 按功能分为了三个类 ，计算字符数，计算单词数，计算行数。然后在主程序中new三个类，当需要进行着三个功能时就调用其中的函数。

二.代码说明

1.主程序（包含输出文件的方法）

static void Main(string[] args)
        {
            string cmd = "";
            while (cmd != "leave")
            {               
                int i;
                int charCount, wordCount, lineCount;
                string testFile;
                string outFile;
                Console.Write("wc.exe ");
                cmd = Console.ReadLine();
                string[] arrMessSplit = cmd.Split(' ');
                List<string> arrParameter = new List<string>();
                for (i = 0; i < arrMessSplit.Length; i++)
                {
                    arrParameter.Add(arrMessSplit[i]);
                }
                bool isOut = false;
                for (i = 0; i < arrMessSplit.Length - 1; i++)
                {

                    if (arrParameter[i] == "-o")
                    {
                        isOut = true;
                    }
                }

                CharCount cc = new CharCount();
                WordCount wc = new WordCount();
                LineCount lc = new LineCount();
                if (isOut)
                {
                    testFile = arrParameter[arrParameter.Count - 3];
                    for (i = 0; i < arrMessSplit.Length - 1; i++)
                    {
                        if (arrParameter[i] == "-c")
                        {
                            cc.CC(testFile);
                        }
                        if (arrParameter[i] == "-w")
                        {
                            wc.WC(testFile);
                        }
                        if (arrParameter[i] == "-l")
                        {
                            lc.LC(testFile);
                        }
                    }
                    outFile = arrParameter[arrParameter.Count - 1];
                    FileStream fs = new FileStream(outFile, FileMode.Create);
                    StreamWriter sw = new StreamWriter(fs);
                    sw.Write("{0}，charCount：{1}
", testFile, cc.charCount);
                    sw.Write("{0}，wordCount：{1}
", testFile, wc.wordCount);
                    sw.Write("{0}，lineCount：{1}
", testFile, lc.lineCount);
                    sw.Flush();
                    sw.Close();
                    fs.Close();
                    Console.WriteLine("WriteToFile：{0}", outFile);
                }
                else
                {
                    testFile = arrParameter[arrParameter.Count - 1];
                    for (i = 0; i < arrMessSplit.Length - 1; i++)
                    {
                        if (arrParameter[i] == "-c")
                        {
                            cc.CC(testFile);
                        }

                        if (arrParameter[i] == "-w")
                        {
                            wc.WC(testFile);
                        }

                        if (arrParameter[i] == "-l")
                        {
                            lc.LC(testFile);
                        }
                    }
                }
                Console.ReadLine();
            }
        }
    }
}

2.计算字符数的类

class CharCount
    {

       public  string testFile;
        public int charCount = 0;
        public void CC(string testFile)
        {

            int nChar;
            char[] symbol = { ' ', ',' };
            FileStream file = new FileStream(testFile, FileMode.Open, FileAccess.Read, FileShare.Read);
            StreamReader sr = new StreamReader(file);
            while ((nChar = sr.Read()) != -1)
            {
                charCount++;
            }
            Console.WriteLine("{0}，charCount：{1}", testFile, charCount);
        }
    }

3.计算单词数的类

  class WordCount
    {
       public  string testFile;
        public  int wordCount=0;
        public void WC(string testFile)
        {
            
                int nChar;          
                char[] divide = { ' ', ',' };                                            
                FileStream file = new FileStream(testFile, FileMode.Open,FileAccess.Read, FileShare.Read);
                StreamReader sr = new StreamReader(file);
            while ((nChar = sr.Read()) != -1)
            {
                foreach (char c in divide)
                {
                    if (nChar == (int)c)
                    {
                        wordCount++;
                    }
                }            
            }
            wordCount++;
            Console.WriteLine("{0}，wordCount：{1}", testFile, wordCount);
        }
    }

4.计算行数的类

 class LineCount
    {
       public  string testFile;
        public int lineCount = 0;
        public void LC(string testFile)
        {

            int nChar;
            char[] divide = { ' ', ',' };
            FileStream file = new FileStream(testFile, FileMode.Open, FileAccess.Read, FileShare.Read);
            StreamReader sr = new StreamReader(file);
            while ((nChar = sr.Read()) != -1)
            {
                if (nChar == '
')
                {
                    lineCount++; 
                }
            }
            lineCount++;      
            Console.WriteLine("{0}，lineCount：{1}", testFile, lineCount);
        }
    }

三.测试设计过程

1.测试写入文件

2.测试计算字符，单词和行数的功能
