What is the purpose of Using? [duplicate]

Answer 1

You can use using when the Something class implements IDisposable. It ensures that the object is disposed correctly even if you hit an exception inside the using block.

ie, You don't have to manually handle potential exceptions just to call Dispose, the using block will do it for you automatically.

It is equivalent to this:

Something mySomething = new Something();
try
{
   // this is what's inside your using block
}
finally
{
    if (mySomething != null)
    {
        mySomething.Dispose();
    }
}
