Yes. The classic example would be the params object[] args:
//Allows to pass in any number and types of parameters
public static void Program(params object[] args)
or
void Program(string param1, int param2, params double[] otherParams)
Restrictions:
1. They must all be the same type (or of a child type) as is true for arrays as well
2. Only one params keyword is permitted per method
3. It has to be the last parameter.
