如何将流保存到C＃文件中？

问题：

I have a StreamReader object that I initialized with a stream, now I want to save this stream to disk (the stream may be a .gif or .jpg or .pdf ). 我有一个用流初始化的StreamReader对象，现在我想将此流保存到磁盘（该流可以是.gif或.jpg或.pdf ）。

Existing Code: 现有代码：

StreamReader sr = new StreamReader(myOtherObject.InputStream);

1. I need to save this to disk (I have the filename). 我需要将其保存到磁盘（我有文件名）。
2. In the future I may want to store this to SQL Server. 将来我可能要将其存储到SQL Server。

I have the encoding type also, which I will need if I store it to SQL Server, correct? 我也有编码类型，如果将其存储到SQL Server，我会需要该编码类型，对吗？
