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();     }   } } 

Edit

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

Answer 2

Yes. A using statement translates to approximately the following construct:

IDisposable x; try {     ... } finally {     x.Dispose(); }
