dotnet 中的 FileStream 和 StreamWriter 有什么不同?

What is different between FileStream and StreamWriter in dotnet?

一个 FileStream 是一个 Stream.像所有 Streams 一样，它只处理 byte[] 数据.

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

A StreamWriter : TextWriter，是一个流装饰器.TextWriter 将字符串或字符等文本数据编码为 byte[]，然后将其写入链接的 Stream.

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

你应该在什么上下文中使用它?他们的优势和劣势是什么?

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

当您有 byte[] 数据时，您使用裸 FileStream.当你想写文本时，你添加一个 StreamWriter.使用格式化程序或序列化程序写入更复杂的数据.

You use a bare FileStream when you have byte[] data. You add a StreamWriter when you want to write text. Use a Formatter or a Serializer to write more complex data.

是否可以将这两者合二为一?

Is it possible to combine these two into one?

是的.你总是需要一个 Stream 来创建一个 StreamWriter.辅助方法 System.IO.File.CreateText("path") 将组合创建它们，然后您只需要 Dispose() 外部编写器.

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