Disposables, Using & Try/Catch Blocks

Question

Having a mental block today, need a hand verifying my logic isn\'t fubar\'ed.

Traditionally I would do file i/o similar to this:

FileStream fs = null

You're just being paranoid and it will work the way you intend it to :)

A using statement is equivalent to a try/finally block, whether it's inside a try/catch or not.

So your code is similar to:

try
{
   FileStream fs = null;
   try
   {
       fs = File.Open("Foo.txt", FileMode.Open);
       // Do stuff
   }
   finally
   {
       if (fs != null)
       {
           fs.Dispose();
       }
   }
}
catch(Exception)
{
   /// Handle Stuff
}
