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 ");
}
}
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();
}
}
}
}
}
