returning in the middle of a using block

Question

Something like:

using (IDisposable disposable = GetSomeDisposable())
{
    //.....
    //......
    return Stg();
}

I believe it is not a p

Answer 1

It's perfectly fine.

You are apparently thinking that

using (IDisposable disposable = GetSomeDisposable())
{
    //.....
    //......
    return Stg();
}

is blindly translated into:

IDisposable disposable = GetSomeDisposable()
//.....
//......
return Stg();
disposable.Dispose();

Which, admittedly, would be a problem, and would make the using statement rather pointless --- which is why that's not what it does.

The compiler makes sure that the object is disposed before control leaves the block -- regardless of how it leaves the block.
