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

 1 //所读取的文件
 2 Stream inputStream=File.OpenRead(
 3 @"C:\test\source\test1.cs");
 4 //要写入的文件
 5 Stream outputStream=File.Openwrite(
 6 @"C:\test\source\test1.bak");
 7 
 8 //创建一个保存字节的缓存
 9 byte [] buffer=new Byte[SizeBuffer];
10 int byteRead;
11 
12 whil(byteRead=inputStream.Read(buffer,0,SizeBuff))>0)
13 {
14     outputStream.Write(buffer,0,byteRead);
15 }

2.缓存数据流

 

 

 1 //创建
 2 
 3 Stream inputStream=File.OpenRead(
 4 
 5 @"C:\test\source\folder3.cs");
 6 
 7 Stream outputStream=File.OpenWrite(
 8 
 9 @"C:\test\source\folder3.bak");
10 
11 //添加缓存数据流
12 
13 BufferedStream bufferedInput=
14 
15     new BufferedStream(inputStream);
16 
17 BufferedStream bufferedOutput=
18 
19     new BufferedStream(OutputStream);
20 
21 byte[] buffer=new Byte[SizeBuffer];
22 
23 int bytesRead;
24 
25 while((bytesRead=
26 
27 bufferedInput.Read(buffer,0,SizeBuff))>0)
28 
29 {
30 
31     bufferedOutput.Write(buffer,0,bytesRead);
32 
33 }
