How do I save a stream to a file in C#?

Question

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).

Existing Code:

StreamReader sr = new StreamReader(myOtherObject.InputStream); 

1. I need to save this to disk (I have the filename).
2. In the future I may want to store this to SQL Server.

I have the encoding type also, which I will need if I store it to SQL Server, correct?

As highlighted by Tilendor in Jon Skeet's answer, streams have a CopyTo method since .NET 4.

var fileStream = File.Create("C:\\Path\\To\\File"); myOtherObject.InputStream.Seek(0, SeekOrigin.Begin); myOtherObject.InputStream.CopyTo(fileStream); fileStream.Close(); 

Or with the using syntax:

using (var fileStream = File.Create("C:\\Path\\To\\File")) {     myOtherObject.InputStream.Seek(0, SeekOrigin.Begin);     myOtherObject.InputStream.CopyTo(fileStream); }
