goto in Using statement, will the dispose be called?

Question

Consider the following

using (Entity e = new Entity())
{
     goto: Mars
}

Do I have a leak? Not that I'm gonna do such foolishness but just wondering.

Answer 1

Yes Dispose will be called. using translates into try/finally block something like:

try
{
    goto Mars;
    Console.WriteLine("in try");
}
finally
{

    Console.WriteLine("in finally");
}
Mars:
Console.WriteLine("in Mars");

The output from above would be:

in finally
in Mars

You can also test it by creating your own class that implements IDisposable like:

class MyDisposable : IDisposable
{
    public void Dispose()
    {
        Console.WriteLine("Dispose called");
    }
}

and then:

using (MyDisposable myDisposable = new MyDisposable())
{
    goto Mars;
}

Mars:
Console.WriteLine("in Mars");

The output would be:

Dispose called
in Mars
