文件拼接快速批处理文件

遇到一个问题，有三个word文档，要求每个文档里提取一条信息和另外的word文档组合，形成一条新的信息，存入txt文件。

 1  path q = new path();//path类，用来存放路径；
 2         public string wenti(int i, int l) //提取第i行的问题，从wenti l.txt提取；
 3         {
 4             StreamReader wenti = new StreamReader(""+q.questionpath+"wenti" + l + ".txt", Encoding.GetEncoding("GB2312"));
 5             string sLine = "";
 6             ArrayList wentiList = new ArrayList();
 7             while (sLine != null)
 8             {
 9                 sLine = wenti.ReadLine();
10                 if (sLine != null && !sLine.Equals(""))
11                     wentiList.Add(sLine);
12             }
13             wenti.Close();
14             string wenti2 = (string)wentiList[i];
15             return wenti2;
16         }
17         public string daan(int i, int l)//提取第i行答案，从daanl.txt提取；
18         {
19             StreamReader daan = new StreamReader("" + q.questionpath + "daan" + l + ".txt", Encoding.GetEncoding("GB2312"));
20             string[] daan1 = daan.ReadLine().ToString().Split('^');
21 
22             daan.Close();
23             return daan1[i];
24           
25         }
26         public string duihua(int i, int l)//提取i行信息，从duihual.txt读取；

27         {
28             StreamReader duihua = new StreamReader("" + q.questionpath + "duihua" + l + ".txt", Encoding.GetEncoding("GB2312"));
29             string sLine = "";
30             ArrayList duihualist = new ArrayList();
31             while (sLine != null)
32             {
33                 sLine = duihua.ReadLine();
34                 if (sLine != null && !sLine.Equals(""))
35                     duihualist.Add(sLine);
36             }
37             duihua.Close();
38             string duihua2 = (string)duihualist[i];
39             return duihua2;
40         }
41   int i = 0;
42         public void greatfile(int id, int l)
43         {
44             FileStream px = new FileStream(""+q.questionpath+"" + id + ".txt", FileMode.Create);
45             StreamWriter file = new StreamWriter(px, Encoding.Default);
46 
47             file.WriteLine("" + id + "^" + wenti(i, l) + "" + daan(i, l) + "^" + duihua(i, l) + "^" + id + "");
48 
49             file.Close();
50             px.Close();
51             i++;
52         }

先把每个word文档用到的信息提取出来，再通过程序批处理这些问题。
