Question

I’ve been wondering which is faster (or if it even makes a difference), referencing a textbox’s Text property or a string assigned to that value?
Ref textbox.Text

if(textbox1.Text == "A")
{ //do a million iterations
}

Or

string aString = textbox1.Text;
if(aString == "A")
{ //do a million iterations
}

Answer 1

I made just a quick analyze using stop watch: 10.000.000 iterations.

In first case it returns to me: 00:00:21.56

In second case it returns to me: 00:00:42.62

In second case you have Get accessor + new pointer to string every iteration, so its slower.

Hope this helps.

EDIT

I put all code of any case inside the iteration. Seems that is the quetion.
