C#课后小试8

Stream（数据流）

命名空间：System.IO

我们看一下文件的读写

1.二进制文件

//所读取的文件
Stream inputStream=File.OpenRead(
@"C：	estsource	est1.cs");
//要写入的文件
Stream outputStream=File.Openwrite(
@"C：	estsource	est1.bak");

//创建一个保存字节的缓存
byte [] buffer=new Byte[SizeBuffer];
int byteRead;

whil(byteRead=inputStream.Read(buffer,0,SizeBuff))>0)
{
    outputStream.Write(buffer,0,byteRead);
}

2.缓存数据流

//创建

Stream inputStream=File.OpenRead(

@"C:	estsourcefolder3.cs");

Stream outputStream=File.OpenWrite(

@"C:	estsourcefolder3.bak");

//添加缓存数据流

BufferedStream bufferedInput=

    new BufferedStream(inputStream);

BufferedStream bufferedOutput=

    new BufferedStream(OutputStream);

byte[] buffer=new Byte[SizeBuffer];

int bytesRead;

while((bytesRead=

bufferedInput.Read(buffer,0,SizeBuff))>0)

{

    bufferedOutput.Write(buffer,0,bytesRead);

}
