Question

using System;

namespace area
{
    class Program
    {
        static void Main(string[] args)
        {
             double basse;
             double height;                   

             Console.WriteLine("Enter your base length: ");
             basse = Convert.ToDouble(Console.ReadLine());

             Console.WriteLine( "Enter the height: ");
             height = Convert.ToDouble(Console.ReadLine());                    

             double area = Program.triangleArea(basse, height);
             Console.WriteLine("Your area is {0:f3}", area);
             Console.ReadLine();                    
             double pryrmid = Program.pyramidVolume( triangleArea);
             Console.WriteLine(" Pyramid Volume is {0:f3}" , pryrmid);                                       
        }

        public static double triangleArea(double basse, double height)
        {
            return (0.5 * basse) * height;
        }             
        public static double pyramidVolume (double triangleArea)                
        {
            return (1/3) * triangleArea;                
        }        
    }                       
}

I’m trying the calculate the volume of a pryamid using the methods ive defined.

I keep getting the error

Argument ‘1’: cannot convert from ‘method group’ to ‘double’ (CS1503)
– \vmware-host\Shared Folders\Documents\SharpDevelop Projects\WS_6_D\WS_6_D\Program.cs:28,57

and

The best overloaded method match for
‘area.Program.pyramidVolume(double)’ has some invalid arguments
(CS1502) – \vmware-host\Shared Folders\Documents\SharpDevelop
Projects\WS_6_D\WS_6_D\Program.cs:28,34

I was wondering if someone could help me get on the right track.

Answer 1

The problem is that triangleArea in
double pryrmid = Program.pyramidVolume( triangleArea); is not a variable, hence it points to the static method.

Try double pryrmid = Program.pyramidVolume( area); instead.
