C#实现文本文件合并

C#实现文本文件合并

读取n个文本文件，把文件内容合并到一个文本文件中。主要用了FileStream的ReadByte和WriteByte方法：

class FileCombine {      public void CombineFile(String[] infileName,String outfileName)      {                  int b;             int n=infileName.Length;             FileStream[] fileIn=new FileStream[n];             using (FileStream fileOut = new FileStream(outfileName, FileMode.Create))             {                 for (int i = 0; i < n; i++)                 {                     try                     {                         fileIn[i] = new FileStream(infileName[i], FileMode.Open);                         while ((b = fileIn[i].ReadByte()) != -1)                             fileOut.WriteByte((byte)b);                     }                     catch (System.Exception ex)                     {                         Console.WriteLine(ex.Message);                     }                     finally                     {                         fileIn[i].Close();                     }                                     }             }      } }

调用方法如下：

class TestCombine {      public static void Main(String[] args)      {          FileCombine c=new FileCombine();          String[] file=new String[2];          file[0]="aa.txt";          file[1]="bb.txt";          c.CombineFile(file,"cc.txt");     } }
