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）

 1 static void Main(string[] args)
 2         {
 3             string cmd = "";
 4             while (cmd != "leave")
 5             {               
 6                 int i;
 7                 int charCount, wordCount, lineCount;
 8                 string testFile;
 9                 string outFile;
10                 Console.Write("wc.exe ");
11                 cmd = Console.ReadLine();
12                 string[] arrMessSplit = cmd.Split(' ');
13                 List<string> arrParameter = new List<string>();
14                 for (i = 0; i < arrMessSplit.Length; i++)
15                 {
16                     arrParameter.Add(arrMessSplit[i]);
17                 }
18                 bool isOut = false;
19                 for (i = 0; i < arrMessSplit.Length - 1; i++)
20                 {
21 
22                     if (arrParameter[i] == "-o")
23                     {
24                         isOut = true;
25                     }
26                 }
27 
28                 CharCount cc = new CharCount();
29                 WordCount wc = new WordCount();
30                 LineCount lc = new LineCount();
31                 if (isOut)
32                 {
33                     testFile = arrParameter[arrParameter.Count - 3];
34                     for (i = 0; i < arrMessSplit.Length - 1; i++)
35                     {
36                         if (arrParameter[i] == "-c")
37                         {
38                             cc.CC(testFile);
39                         }
40                         if (arrParameter[i] == "-w")
41                         {
42                             wc.WC(testFile);

44                         if (arrParameter[i] == "-l")
45                         {
46                             lc.LC(testFile);
47                         }
48                     }
49                     outFile = arrParameter[arrParameter.Count - 1];
50                     FileStream fs = new FileStream(outFile, FileMode.Create);
51                     StreamWriter sw = new StreamWriter(fs);

", testFile, lc.lineCount);
55                     sw.Flush();
56                     sw.Close();
57                     fs.Close();
58                     Console.WriteLine("WriteToFile：{0}", outFile);
59                 }
60                 else
61                 {
62                     testFile = arrParameter[arrParameter.Count - 1];

67                             cc.CC(testFile);
68                         }
69 
70                         if (arrParameter[i] == "-w")
71                         {
