Good solution but the simple arrays use "Length" property for array size instead of count method.

@Dubas : Really thanks ! This is mix up with javaScript I am working on write now.

@infoSetu : there is no count() method on an array ;) int nb = s.Split('_').GetLength(0) - 1;

String is an IEnumerable of char, you can do something like:

myString.Where(c => c == '_').Count();
