C#实现文本文件合并 _17

读取n个文本文件，把文件内容合并到一个文本文件中。重要用了FileStream的ReadByte跟WriteByte办法。

 
class FileCombine

{
     public void CombineFile(String[] infileName,String outfileName)

     {     
            int b;

            int n=infileName.Length;

            FileStream[] fileIn=new FileStream
;

            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();
                    }
                    
                }
            }
     }
}

class FileCombine
{
public void CombineFile(String[] infileName,String outfileName)
{
int b;
int n=infileName.Length;
FileStream[] fileIn=new FileStream
;
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();
}

}
}
}
}

调用方式如下：

 
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");

    }
}

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");
}
}
