String

Question

If i have a string like this : string test =  true +  dmy 1980  +   Is it possible to check whether runprogram parameters appservers are in the string With Indexof you can only check for one string: IndexOf(runprogram0) So i want to check whether several words are in a string Thx in advance

It's possible with regular expressions but it'll be too complicated and slow I think. Use several IndexOf() with &&. Next it would be better to find   instead of runprogram eg. find all the letters to avoid false findings. What about upper/lowercase letters? May be use ToUpper() method if it's case insensitive: test.IndexOf(someword)>=0 && test.IndexOf(nextword)>=0 ...
