c# - If an Exception happens within a using statement does the object still get disposed?

Question

If an Exception happens within a using statement does the object still get disposed?

The reason why I'm asking is because I'm trying to decide on whether to put a try caught around the whole code block or within the inner using statement. Bearing in mind certain exceptions are being re-thrown by design within the catch block.

using (SPSite spSite = new SPSite(url))
{
   // Get the Web
   using (SPWeb spWeb = spSite.OpenWeb())
   {
       // Exception occurs here
   }
}

Answer 1

Yes, they will.

using(SPWeb spWeb = spSite.OpenWeb())
{
  // Some Code
}

is equivalent to

{
  SPWeb spWeb = spSite.OpenWeb();
  try
  {

    // Some Code
  }
  finally
  {
    if (spWeb != null)
    {
       spWeb.Dispose();
    }
  }
}

After answering this question, I wrote a more in depth post about the IDisposable and Using construct in my blog.
