什么是DOTNET的FileStream和StreamWriter之间有什么不同？

A 的FileStream 是流。像所有的流只用涉及的byte [] 数据。

A 的StreamWriter 是的TextWriter ，一个流的装饰。一个TextWriter的转换或编码像字符串或字符为字节[] 文本数据，然后将其写入到链接流。

什么情况下，你应该使用它？什么是他们的优势和劣势？

您使用裸露的FileStream当你有字节[] 数据。您添加的StreamWriter 当你想要写的文字。

是的。你总是需要一个流来创建的StreamWriter。 System.IO.File.CreateText（路径）将联合创建它们，然后你只需要Dispose（）方法外作家。

解决方案

What is different between FileStream and StreamWriter in dotnet?

A FileStream is a Stream. Like all Streams it only deals with byte[] data.

A StreamWriter is a TextWriter, a Stream-decorator. A TextWriter converts or encodes Text data like string or char to byte[] and then writes it to the linked Stream.

What context are you supposed to use it? What is their advantage and disadvantage?

You use a bare FileStream when you have byte[] data. You add a StreamWriter when you want to write text.

Is it possible to combine these two into one?

Yes. You always need a Stream to create a StreamWriter. System.IO.File.CreateText("path") will create them in combination and then you only have to Dispose() the outer writer.
