系列4:文件操作以及读写文件

1。文件或者目录操作可以用到FileInfo,File,DirectoryInfo,Directory类:

FileInfo和File的主要区别是File的多数方法都是静态方法,DirectoryInfo与Directory区别与此相似。

2。流:In the world of I/O
manipulation, a stream represents a chunk of data. Streams provide a common way to interact with
a sequence of bytes, regardless of what kind of device (file, network connection, printer, etc.) is storing
or displaying the bytes in question.

在实际操作中,我们很少直接使用FileStream,因为它只接受直接数组类型的数据。取而代之的我们使用StreamReader, and StreamWriter这对对FileStream更好的包装。

3。Reader 和 Writer对:

Using the StringWriter and StringReader types, you can treat textual information as a stream of
in-memory characters. This can prove helpful when you wish to append character-based information
to an underlying buffer.
