you code do like this

int iCount = myString.Split( new string[] {"and"}
                           , StringSplitOptions.None )
                     .Length -1;

Try it on this fiddle. https://dotnetfiddle.net/6pcnz3

Doesn't sound like you've put much effort in, but here are 2 options:

  1. Use string.IndexOf to get the index of your first and, and from there, cut the rest, and then use string.Replace to change and to or
  2. Use linq. Split on white space. You can then have a list of words, and then you can replace all the ands that aren't the first to or.
