}
public static voidTest() { List<Func<double, double>> list =
newList<Func<double, double>>() { Double, Square };Process(list, 16);
}
private static voidProcess(List<Func<double,double>> funcs, double value){
double result;
foreach(var actionin funcs) { result = action(value); Console.Write(
$"{action.Method.Name}({value}) ={result}. ");
}
}
The output will be:
