示例1: Main
//引入命名空間
using System;
using System.IO;
class Test
{
public static void Main()
{
// Specify a file to read from and to create.
string pathSource = @"c:\tests\source.txt";
string pathNew = @"c:\tests\newfile.txt";
try
{
using (FileStream fsSource = new FileStream(pathSource,
FileMode.Open, FileAccess.Read))
{
// Read the source file into a byte array.
byte[] bytes = new byte[fsSource.Length];
int numBytesToRead = (int)fsSource.Length;
int numBytesRead = 0;
while (numBytesToRead > 0)
{
// Read may return anything from 0 to numBytesToRead.
int n = fsSource.Read(bytes, numBytesRead, numBytesToRead);
// Break when the end of the file is reached.
if (n == 0)
break;
numBytesRead += n;
numBytesToRead -= n;
}
numBytesToRead = bytes.Length;
// Write the byte array to the other FileStream.
using (FileStream fsNew = new FileStream(pathNew,
FileMode.Create, FileAccess.Write))
{
fsNew.Write(bytes, 0, numBytesToRead);
}
}
}
catch (FileNotFoundException ioEx)
{
Console.WriteLine(ioEx.Message);
}
}
