Hi,

What of this code is faster/more efficient? :

Boolean contains = myString.IndexOf("~", StringComparision.InvariantCultureIgnoreCase)!=-1;

or

Boolean contains = myString.IndexOf('~')!=-1;

I think the second because is a single character, but using the invariant culture ignore case comparer is supposed to be fast too :P

Cheers.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
