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 = ; i < arrMessSplit.Length; i++)
                 {
                     arrParameter.Add(arrMessSplit[i]);
                 }
                 bool isOut = false;
                 for (i = ; i < arrMessSplit.Length - ; 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 - ];
                     for (i = ; i < arrMessSplit.Length - ; 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 - ];
                     FileStream fs = new FileStream(outFile, FileMode.Create);
                     StreamWriter sw = new StreamWriter(fs);
                     sw.Write("{0}，charCount：{1}\r\n", testFile, cc.charCount);
                     sw.Write("{0}，wordCount：{1}\r\n", testFile, wc.wordCount);
                     sw.Write("{0}，lineCount：{1}\r\n", testFile, lc.lineCount);
                     sw.Flush();
                     sw.Close();
                     fs.Close();
                     Console.WriteLine("WriteToFile：{0}", outFile);
                 }
                 else
                 {
                     testFile = arrParameter[arrParameter.Count - ];
                     for (i = ; i < arrMessSplit.Length - ; i++)
                     {
                         if (arrParameter[i] == "-c")
                         {
                             cc.CC(testFile);
                         }

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

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