1，JAVA中操作方法：
import java.io.*;
public class FileInputStreamTest
{
public static void main(String[] args) throws IOException
{
//创建字节输入流
FileInputStream fis = new FileInputStream("FileInputStreamTest.java");
//创建一个长度为1024的竹筒
byte[] bbuf = new byte[1024];
//用于保存实际读取的字节数
int hasRead = 0;
//使用循环来重复“取水”的过程
while((hasRead = fis.read(bbuf))>0)
{
//取出"竹筒"中(字节),将字节数组转成字符串输入
System.out.println(new String(bbuf,0,hasRead));
}
fis.close();
}
}
import java.io.*;
public class FileReaderTest
{
public static void main(String[] args) throws IOException
{
FileReader fr = null;
try
{
//创建字符输入流
fr = new FileReader("FileReaderTest.java");
//创建一个长度为32的"竹筒"
char[] cbuf = new char[32];
//用于保存实际读取的字符数
int hasRead = 0;
//使用循环来重复“取水”的过程
while((hasRead = fr.read(cbuf))>0)
{
//取出"竹筒"中(字节),将字节数组转成字符串输入
System.out.println(new String(cbuf,0,hasRead));
}
}
catch (IOException ioe)
{
ioe.printStackTrace();
}
finally
{
//关闭文件输入流
if(fr != null)
{
fr.close();
}
}
}
}
2，C#中操作方法：

* Stream 和 byte[] 之间的转换
* - - - - - - - - - - - - - - - - - - - - - - - */
/// <summary>
/// 将 Stream 转成 byte[]
/// </summary>
public byte[] StreamToBytes(Stream stream)
{
byte[] bytes = new byte[stream.Length];
stream.Read(bytes, 0, bytes.Length);
// 设置当前流的位置为流的开始
stream.Seek(0, SeekOrigin.Begin);
return bytes;
}
/// <summary>
/// 将 byte[] 转成 Stream
/// </summary>
public Stream BytesToStream(byte[] bytes)
{
Stream stream = new MemoryStream(bytes);
return stream;
}
/* - - - - - - - - - - - - - - - - - - - - - - - -
* Stream 和 文件之间的转换
* - - - - - - - - - - - - - - - - - - - - - - - */
/// <summary>
/// 将 Stream 写入文件
/// </summary>
public void StreamToFile(Stream stream,string fileName)
{
// 把 Stream 转换成 byte[]
byte[] bytes = new byte[stream.Length];
stream.Read(bytes, 0, bytes.Length);
// 设置当前流的位置为流的开始
stream.Seek(0, SeekOrigin.Begin);
// 把 byte[] 写入文件
FileStream fs = new FileStream(fileName, FileMode.Create);
BinaryWriter bw = new BinaryWriter(fs);
bw.Write(bytes);
bw.Close();
fs.Close();
}
/// <summary>
/// 从文件读取 Stream
/// </summary>
public Stream FileToStream(string fileName)
{
// 打开文件
FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read);
// 读取文件的 byte[]
byte[] bytes = new byte[fileStream.Length];
fileStream.Read(bytes, 0, bytes.Length);
fileStream.Close();
// 把 byte[] 转换成 Stream
Stream stream = new MemoryStream(bytes);
return stream;
