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 "); 
    } 
}
