一、拓展代码
（1）主函数
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace wc { class Program { static void Main(string[] args) { string msg = ""; //输入字符串 WC wordcount = new WC(); //引用WC类 Char[] c = {' '};//分隔符 while (msg != "exit") { msg = Console.ReadLine(); //输入操作字符串 string[] msgSplit = msg.Split(c, StringSplitOptions.RemoveEmptyEntries);//将字符串按空格分割 wordcount.Operator(msgSplit); } } } }
（2）WC类
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace wc { public class WC { public string filename; // 文件名 public string[] filenames; //多个文件名 public string stopwordfile; //停用词文件名 public string[] msgSplit; //所有参数数组 public string outfile; //输出文件名 public string str; //输出字符串 public int iccount; // 字符数 public int iwcount; // 单词数 public int ilcount; // 总行数 public int inulllinecount; //空行数 public int icodelinecount; //代码行数 public int inotelinecount; //注释行数 //引入输入字符串，并对字符串进行处理 public void Operator(string[] msgSplit) { this.msgSplit = msgSplit; //引入操作数组 int Length; Length = msgSplit.Length; foreach (string s in msgSplit) { if (s == "-e") { Length = Length - 2; } else if (s == "-o") { Length = Length - 2; } } this.filename = msgSplit[Length - 1];//获取文件名 if (msgSplit[0] == "wc.exe") { foreach (string s in msgSplit) { if (s == "-s") { //获取所有后缀名符合的文件 string fileDir = Environment.CurrentDirectory; filenames = Directory.GetFiles(fileDir, filename); } else if (s == "-e") { //获取停用词表文件 for (int i = 0; i < msgSplit.Length; i++) { if (msgSplit[i] == "-e") { stopwordfile = msgSplit[i + 1]; } } } } if (filenames == null) { SuperCount(filename); BaseCount(filename, stopwordfile); Display(filename); } else { for (int i = 0; i < filenames.Length; i++) { SuperCount(filenames[i]); BaseCount(filenames[i], stopwordfile); Display(filenames[i]); } } } else { Console.WriteLine("输入指令不存在！请重新输入。。。"); } } // 统计基本信息：字符数 单词数 行数 public void BaseCount(string filename,string stopwordfile) { try { // 打开文件 FileStream file = new FileStream(filename, FileMode.Open, FileAccess.Read, FileShare.Read); StreamReader sr = new StreamReader(file); int nChar; int charcount = 0; int wordcount = 0; int linecount = 0; //定义一个字符数组 char[] symbol = { ' ', '\t','\r', ',', '.', '?', '!', ':', ';', '\'', '\"', '\n', '{', '}', '(', ')', '<','>','+' ,'-','*', '='}; while ((nChar = sr.Read()) != -1) { charcount++; // 统计字符数 if (nChar == '\n') { linecount++; // 统计行数 } } sr.Close(); file = new FileStream(filename, FileMode.Open, FileAccess.Read, FileShare.Read); sr = new StreamReader(file); string words = sr.ReadToEnd(); string[] word = words.Split(symbol, StringSplitOptions.RemoveEmptyEntries);//将文件内所有单词分割 if (stopwordfile != null) { //有停用词表 FileStream stopfile = new FileStream(stopwordfile, FileMode.Open, FileAccess.Read, FileShare.Read); StreamReader stopsr = new StreamReader(stopfile); string stopwords = stopsr.ReadToEnd(); string[] stopword = stopwords.Split(symbol, StringSplitOptions.RemoveEmptyEntries);//将停用词表内所有单词分割 foreach (string s in word) { foreach (string stop in stopword) { if (s != stop) { wordcount++;//统计单词数 } } } stopsr.Close(); } else { //没有停用词表 wordcount = word.Length; } sr.Close(); iccount = charcount; iwcount = wordcount; ilcount = linecount + 1; } catch (IOException ex) { Console.WriteLine(ex.Message); return; } } // 统计代码行 空行 注释行 public void SuperCount(string filename) { try { // 打开文件 FileStream file = new FileStream(filename, FileMode.Open, FileAccess.Read, FileShare.Read); StreamReader sr = new StreamReader(file); String line; int nulllinecount = 0; int codelinecount = 0; int notelinecount = 0; while ((line = sr.ReadLine()) != null) { // 除去每行开头多余空格和格式控制字符 line = line.Trim(' '); line = line.Trim('\t'); // 空行 if (line == "" || line.Length <= 1) { nulllinecount++; } // 注释行 else if (line.Substring(0, 2) == "//" || line.Substring(1, 2) == "//") { notelinecount++; } // 代码行 else { codelinecount++; } } inulllinecount = nulllinecount; icodelinecount = codelinecount; inotelinecount = notelinecount; sr.Close(); } catch (IOException ex) { Console.WriteLine(ex.Message); return; } } // 打印信息 public void Display(string filename) { //将操作命令以-c,-w,-l的顺序输出 foreach (string s in msgSplit) { if (s == "-c") //遍历第一次找-c命令，有的话输出字符数 { Console.WriteLine(filename + ",字符数：{0}", iccount); str = filename + ",字 符 数:" + iccount + "\r\n"; File.AppendAllText("result.txt", str, Encoding.Default); } } foreach (string s in msgSplit) { if (s == "-w") //遍历第二次找-w命令，有的话输出单词数 { Console.WriteLine(filename + ",单词数：{0}", iwcount); str = filename + ",单 词 数:" + iwcount + "\r\n"; File.AppendAllText("result.txt", str, Encoding.Default); } } foreach (string s in msgSplit) { if (s == "-l") //遍历第三次找-l命令，有的话输出行数 { Console.WriteLine(filename + ",行 数：{0}", ilcount); str = filename + ",总 行 数:" + ilcount + "\r\n"; File.AppendAllText("result.txt", str, Encoding.Default); } } foreach (string s in msgSplit) { if (s == "-a") //遍历第四次找-a命令，有的话输出代码行/空行/注释行 { Console.WriteLine(filename + ",代码行/空行/注释行：{0}/{1}/{2}", icodelinecount, inulllinecount, inotelinecount);

//引入输出文件名 foreach (string st in msgSplit) { if (st == "-c") //遍历第一次找-c命令，有的话将字符数存入输出文档 { str = filename + ",字 符 数:" + iccount + "\r\n"; File.AppendAllText("" + outfile + "", str, Encoding.Default); } } foreach (string st in msgSplit) { if (st == "-w") //遍历第二次找-w命令，有的话将单词数存入输出文档 { str = filename + ",单 词 数:" + iwcount + "\r\n";

} } } } Console.WriteLine(); } } }
（3）单元测试代码
using System; using System.Text; using System.Collections.Generic; using System.Linq; using Microsoft.VisualStudio.TestTools.UnitTesting; using System.IO; namespace TestWC { [TestClass] public class UnitTest1 { [TestMethod] public void TestBaseCount() { //测试统计字符数，单词书，行数 wc.WC wordcount = new wc.WC(); string filename = "F://徐建敏//wc//wc//bin//Debug//file1.c"; string stopwordfile = "F://徐建敏//wc//wc//bin//Debug//stop.txt"; wordcount.BaseCount(filename, stopwordfile); int ccount = wordcount.iccount; int wcount = wordcount.iwcount; int lcount = wordcount.ilcount; Assert.AreEqual(87, ccount); Assert.AreEqual(10, wcount); Assert.AreEqual(7, lcount); } [TestMethod] public void TestOperator() { //测试对输入字符串进行引入并处理 wc.WC wordcount = new wc.WC(); string[] msgSplit = { "wc.exe", "-c", "-w", "-l", "F://徐建敏//wc//wc//bin//Debug//file1.c"}; wordcount.Operator(msgSplit); string filename = wordcount.filename; string stopword = wordcount.stopwordfile; string[] filenames = wordcount.filenames; Assert.AreEqual("F://徐建敏//wc//wc//bin//Debug//file1.c", filename); Assert.AreEqual(null, stopword); Assert.AreEqual(null, filenames); } [TestMethod] public void TestSuperCount() { //测试统计代码行 空行 注释行 wc.WC wordcount = new wc.WC(); string filename = "F://徐建敏//wc//wc//bin//Debug//file1.c"; wordcount.SuperCount(filename); int codecount = wordcount.icodelinecount; int nullcount = wordcount.inulllinecount; int notecount = wordcount.inotelinecount; Assert.AreEqual(4, codecount); Assert.AreEqual(2, nullcount); Assert.AreEqual(1, notecount); } [TestMethod] public void TestDisplay() { //测试输出 wc.WC wordcount = new wc.WC(); string[] msg={"wc.exe","-c","F://徐建敏//wc//wc//bin//Debug//file1.c"}; wordcount.msgSplit = msg; string filename = "F://徐建敏//wc//wc//bin//Debug//file1.c"; wordcount.Display(filename); string result = wordcount.str; Assert.AreEqual("F://徐建敏//wc//wc//bin//Debug//file1.c,字 符 数:0\r\n", result); } } }
二、拓展功能展示
三、静态代码检查
四、单元测试
五、个人总结
通过这次作业，学会了使用VS自带的单元测试工具。同时，结队编程互相讨论，互相提供灵感，对编程的帮助很大。但是实在没有找到静态代码测试工具，只能看VS自带的错误提示，没有学习到静态代码工具的使用，有一些遗憾。
