"is" operator efficiency

Yes! is operator is lightweight and fast, but if you need something like Checking Type and Then parsing it to that time, Then use a better and recommended way that is as Operator:

Code with is:

if(aControl is Button)

{

Button b = (Button) button1;

}

Code with as:

Button b = button1 as Button;

if(b == null) // was not a Button

{

// Do Something

}

else // is Button and Also Parsed

{

//Do Something

}

So its a short and fast too, So it depends on your use. as eliminates double casting of a type from from is and then by real casting.

Hope it help!
