What is the most efficient way to ask a MethodInfo how many parameters it takes?

Question

What is the most efficient way to ask a MethodInfo if it accepts parameters and, if so, how many?

My current solutions would be: methodInfo.GetParameters().Any() and methodInfo.GetParameters().Count().

Is this the most efficient way?

Since I don't actually need any of the ParameterInfo objects, is there a way to do this without a call to GetParameters()?
