arrow_back How do I use a void variable?

Question

My knowledge of c# is limited) Explain how, after declaring an array, to calculate the sum of the minimum and maximum values. Apparently my program is wrong, because I get the error: no conversion of void type variable to int.

static void Main(string[] args)
     { 
        double [] Data = new double[5];
        int i = 0;
       while (i < 5)
        {
           Data[i] = double.Parse(Console.ReadLine());
           Console.WriteLine();
           i++;
        }   
        int x =  
     Console.WriteLine(Data.Min());
        int y =
        Console.WriteLine(Data.Max());
        Console.WriteLine(x + y);
   }

Translate Void into Russian and I think the question goes away.
And in essence, look at the WriteLine method and what it returns, look at the Min & Max method, look at what they return.
First you need to put the result of the Min, Max method into a variable, and then output it.

LiptonOlolo , that's clear, can you help fix the program?

Thank you all, I understand that the method Data.Min returns values of type double, further action is clear, thank you all)

evans_85 , updated the commentary.

evans_85 , int x = Console.WriteLine(Data.Min());

There's no way Data.Min() gets into the X variable

I would recommend it this way. Just look at it and think about why

using System;
using System.Linq;

namespace ConsoleApp99
{
    internal class Program
    {
        private static void Main()
        {
            const int size = 5;
            var data = new double[size];
            var i = 0;
            Console.WriteLine("Enter float or double");
            do
            {
                var parsed = double.TryParse(Console.ReadLine(), out var dp);
                if (!parsed) continue;
                data[i] = dp;
                i++;
            } while (i < size);

            var x = data.Min();
            Console.WriteLine($"min: {x}");
            var y = data.Max();
            Console.WriteLine($"max: {y}");
            Console.WriteLine($"sum  x + y: {x + y}");
        }
    }
}
