- This very common pattern that we've now seen of,…using a try finally block to make sure we release resources,…is so common that there is support…in the .NET Framework for this pattern.…And the support comes in the form of an interface…called IDisposable.…So watch this.…I will copy and paste the whole method.…Rename the method to number 12.…And what you will notice is fs, way up here..…
This FileStream implements the interface called IDisposable.…I will press Ctrl dot, so we add the using statement…at the top using system.…So this variable of type IDisposable,…is special in a number of ways,…but, first, how do I know FileStream…implements IDisposable?…Click on the name of the type and you can press F12,…we could use the proper shortcut to go to definition.…And so, what happens is .NET looks at the class definition…and writes out, in-text,…what it sees when it looks at…the underlined definitions, at the method data.…
And so, FileStream is inheriting from Stream, okay.…So let Stream, press F12 or go to definition,…
