Ok lets say I have a string composed of this text (including the quotes)

Hello "bob how are" you?

what would be the fastest way to search that string to see if it contains a " (quote marks)? I know i could use the mid instruction and put it in the middle of a loop and just check every char one at a time, but that is slow. I cant split the string because i want to keep the " not use it as the dilimiter. Does vb.net have a search function like c++? Because i have a feeling vb would have a built in function that is faster then anything i can write.
