Which syntax is more efficient?

[Andy]

I'm trying to optimize a few methods while I'm converting the code from VB.net ( version 1.1 ) to c# ( version 2.0 )

I found a lot of these statements to compare strings :

If String.Compare(e.CommandName, "viewcollection", True) = 0 Then

I have chosen to rewrite them as simply :

if(e.CommandName.ToLower() == "viewcollection")

is either way any more efficient than the other?

Normally, this wouldn't be such a big deal but I found hundreds of these statements and want to minimize overhead as much as possible.

Statement 1 uses a static(shared) method of the string class and statement 2 simply does a comprison. Does statement 2 create a copy of the string and therefore creates more overhead?
