客户端开发小结
因为项目需要，改web端项目到客户端，就开始了第一次客户端开发。
采用c#语言开发，其实还是蛮简单的，直接拉控件摆放到面板上，需要发生点击事件就点两下，出来一个双击函数，在函数里写要操作的方法就好了。
这次主要遇到的难点有两方面吧：1、c#调用外部可执行程序gawk；2、awk的使用
1、c#调用外部可执行程序
这里为什么要调用gawk咧？主要是考虑到，程序的主要用途是进行文本的处理，而对于文本的处理awk（gawk是awk的windows版本）处理起来相当简单。
怎么调用gawk咧？
1: Process p = new Process();
2: p.StartInfo.FileName = "cmd.exe";
3: p.StartInfo.UseShellExecute = false;
4: p.StartInfo.RedirectStandardInput = true;
5: p.StartInfo.RedirectStandardOutput = true;
6: p.StartInfo.RedirectStandardError = true;
7: p.StartInfo.CreateNoWindow = true;
8: p.Start();
9: p.StandardInput.WriteLine("cd " + newLocation);
10: //按照qq号进行过滤
11: p.StandardInput.WriteLine("gawk ..../*此处省略*/);
12: p.StandardInput.WriteLine("exit");
13: string strRst = p.StandardOutput.ReadToEnd();
14: p.Close();
这里犯了一个错误就是我最开始以为可以直接调用gawk.exe执行文件，但是发现完全行不通，最后还是采用这种本办法，先调用cmd.exe，再进入gawk的目录，调用gawk.exe，执行gawk的命令。
这里的
1: p.StandardInput.WriteLine("gawk ..../*此处省略*/);
可以不断的write新的语句进去，感觉应该是同步执行的。但是这里如果出现c#代码，就会异步执行，注意。
2、awk的使用总结
awk的使用总结分为一下几点：文件操作、多文件操作
文件操作：
awk 双引号+大括号+执行语句+反大括号+反双引号；（在windows下需用双引号，linux下用单引号）。
1: gawk "{if(!(++a[substr($1,0,1)]>1)){print $0 >> \"temp2013-04-22-04-14-48.txt\"}else{print $0 >> \".\\sadQQData\\sadQQData2013-04-22-04-14-48.txt\"}}" C:\\Users\\share\\Desktop\\数据包过滤系统\\test.txt
对于去重的方法,网上有很多啦,比如:
1: gawk "!(a[$1]++)" 22.txt 去掉重复的数据条,会保留一条
2: gawk "!(++a[$1]>6)" 22.txt 处理能包涵超过6个重复数据的文本,会保留6条
但是对于要去掉所有重复的数据，即只要重复了，一条也不保留的情况。就有点够呛了。我的处理方式是：
首先按照去重的方式过滤一遍，把干净数据包和脏数据包放到两个文件中，这时候脏数据包里的所有数据都表示在源数据包中重复出现超过次数的数据，干净数据包里的数据有正常数据和出现超过次数的数据的几条（看去重的时候阈值）。这个时候再用两个文件比较，把在臧数据包中出现过的数据从干净数据包中去掉。这个时候就是完全干净的数据包了。
多文件处理：
这个一定要看下NR(Number of Record)、FNR(File Number of Record)、NF(NUmber of Field)。
通过对NR=FNR，表示读取第一个文件，NR>FNR，表示读取第二个文件内容。
了解了这几个东东对于多文件操作就很简单啦。看查看：http://www.letuknowit.com/topics/20120329/sample-about-awk-build-in-variable-nr-fnr-nf.html
