wordCount的c#实现
本次作业地址:https://edu.cnblogs.com/campus/xnsy/Test/homework/2203
（1）互审代码情况
在此次作业中，我们互相写了完整的wordCount代码后，互相进行了代码的审查，发现了很多问题，下列举几个模块审查问题
在合作同学的代码中他将对数据的处理写为一类，读写，操作，写出，写为一类，显得主函数太过冗长，我将代码的读入，操作，主函数归为三类
使得代码更为精简
基本功能概述:
wc.exe -c file.c //返回文件 file.c 的字符数
wc.exe -w file.c //返回文件 file.c 的单词总数
wc.exe -l file.c //返回文件 file.c 的总行数
wc.exe -o outputFile.txt //将结果输出到指定文件outputFile.txt
拓展功能概述:
wc.exe -a file.c //统计代码行/空行/注释行
wc.exe -s //调用其他-指令
注释：
代码行：本行包括多于一个字符的代码。
空 行：本行全部是空格或格式控制字符，如果包括代码，则只有不超过一个可显示的字符，例如“{”。
注释行：本行不是代码行，并且本行包括注释。一个有趣的例子是有些程序员会在单字符后面加注释：}//注释
在这种情况下，这一行属于注释行。
如下图中的空行/注释行/代码行的计数方法中，我们发现将注释行的if语句嵌套,后对codecount的计数会发生影响
于是进行了改正：
还有很多不便一一赘述，将在下列测试中继续枚举。

性能测试
测试工具：VS2013的性能测试工具
原来对字符数等命令统计使用的是for循环遍历的方法
代码如下
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace WordCount
{

{
//打开.c文件并将内容以字符串形式读取出来

{

byte[] array = new byte[fs.Length];
fs.Read(array,0, array.Length);
fs.Close();
string str = Encoding.UTF8.GetString(array);
return str;
}
//统计字符数
public int cProcess(string fstr)
{
string str = openFile(fstr);
int charCount = 0;
charCount = str.Length;
foreach(char c in str)
{
if(c==‘\n‘)
{
charCount--;
}
}
StreamWriter sw = new StreamWriter("result.txt", true);
sw.WriteLine(fstr + " 字符数： " + Convert.ToString(charCount));
sw.Close();
return charCount;
}
//统计行数
public int lProcess(string fstr)
{
string str = openFile(fstr);
int lineCount = 1;
foreach (char l in str)
{
if (l == ‘\n‘)
{
lineCount++;
}
}
StreamWriter sw = new StreamWriter("result.txt", true);
sw.WriteLine(fstr + " 行数： " + Convert.ToString(lineCount));
sw.Close();
return lineCount;
}
//统计单词书
public int wProcess(string lstr)
{
string str = openFile(lstr);
int count = 1;
bool isBlank = true;
foreach(char s in str)
{
if(s!=‘ ‘ && s!= ‘\n‘ &&s!=‘,‘&& isBlank==true)
{

}
else if((s==‘ ‘||s==‘\n‘||s==‘,‘)&&isBlank==false)
{

}
}
StreamWriter sw = new StreamWriter("result.txt", true);
sw.WriteLine(lstr + " 单词数：" + Convert.ToString(count - 1));
sw.Close();
return count - 1;
}
//统计代码行/空行/注释行
public string aProcess(string astr)
{
FileStream fs = new FileStream(astr, FileMode.Open);
StreamReader sr = new StreamReader(fs);

while ((lines = sr.ReadLine()) != null)
{

if (lines == "" || lines.Length <= 1)
{
nullLineCount++;
}
else if (lines.Length > 2 && lines.Substring(0, 2) == "//" || lines.Substring(1, 2) == "//")
{
noteLineCount++;
}
else if(lines.Length==2 && lines.Substring(0, 2) == "//")
{
noteLineCount++;
}
else
{
codeLineCount++;
}
}
string complexLineCount = Convert.ToString(codeLineCount) + "/"+Convert.ToString(nullLineCount) +"/"+ Convert.ToString(noteLineCount);
StreamWriter sw = new StreamWriter("result.txt", true);
sw.WriteLine(astr + " 代码行/空行/注释行：" + Convert.ToString(codeLineCount)+"/"+Convert.ToString(nullLineCount)+"/"+Convert.ToString(noteLineCount));
sw.Close();
return complexLineCount;
}
//将统计的数据存入指定文件
public string oProcess(string oFile)
{
System.IO.File.WriteAllText(oFile, string.Empty);

return oFile;
}
}
}

后改用正则表达式的方法，并在对其他代码进行优化后再进行性能测试

总结与收获
在这次wordCount的设计与测试中，我对于软件测试有了较为详细的认知，在学习过程中，我逐渐掌握了c#文件的读写操作，正则表达式的基本应用,控制台命令的实现，
读写命令的逻辑判断，异常或错误的处理方式的运用，同时掌握了白盒测试，静态测试，性能测试的基本操作，在以后的学习，开发过程中，我也会将在这
次开发过程中学到的东西运用到实际中。
