Statements loops

Hello

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class WholeNumbersFor
    {
        private int numOfInPut;
        private int sum;

        public void start();
    
        WriteProgramInfo();
        ReadInPut();
        SumNumbers();
        ShowResults();
    }
    private void ReadInPut()
{

    Console.Write ("Number of Values to sum?");
    NumOfInPut = int.Parse(console.Readkey());
    console.Writeline();
}
    private void WriteProgramInfo()
{
    console.Writeline("\n\n ++++++ Summation of whole numbers ++++++");
    console.Writeline();

}
    private void SumNumbers()
{

    int index;
    int Sum = 0;

    for (index = 0; index < NumOfInPut; index++)
{
}


    private void ShowResults();
{
}

    }

If you put in 9 in to Number of Values to sum? then it going to come up like 9 lines that say for example value no 1 and so on to no 9 that you can enter your number you want in to it.
I don't understand how i'm going to put it in. i know how to do it if you know the value of it but now it is 0 so i dont know how i can make it

I'm looking at this, but the first thing I see is a typo on line 44 (the semi-colon).
Also the closing brace on 19 needs to be moved to 47 or 49.
Also, C# is case-sensitive, so your numOfInPut should match the case of NumOfInPut.

...and if this was meant to be the main module of a console app, you're missing Main().
Did you accidentally delete it?

Your code seems to be all messed up.
You got to use an Array or better a List to store your inputted numbers
Write an input loop for that.
Then loop trough your array or list and sum all the numbers.

Have a look at this and let us know if it needs clarifying:

public void Implementation()
        {
            int mySum = GetNumbers(GetNumberCount()).Sum();
        }
        public int GetNumberCount()
        {
            int iCount = 0;
            Console.WriteLine("Enter number of values to sum: ");
            while (int.TryParse(Console.ReadLine(), out iCount) == false || iCount <= 0)
                Console.WriteLine("Invalid number, try again");
            return iCount;
        }
        public List<int> GetNumbers(int numCount)
        {
            List<int> returnList = new List<int>();
            for (int i = 0; i < numCount; i++)
            {
                int iValue = 0;
                Console.WriteLine("Enter Number " + (i + 1).ToString() + ":");
                while (int.TryParse(Console.ReadLine(),out iValue) == false)
                    Console.WriteLine("Invalid number, try again");
                returnList.Add(iValue);
            }
            return returnList;
        }

thx for the help. i have one questien. if i want to type in numbers in to a loop like this Console.WriteLine("What is the number you want nr " +index ); when it start it goung to say What is the number you want nr 1 and after one i want to put in a number how do i do it?

[thines01]

Console.ReadLine()
...then convert the result to a numeric type like an integer

[Johan__]

thx for it but is it a way to get it next to it and not under it?

[skatamatic]

Using .WriteLine() implies that you want to start a newline (it automatically appends Environment.Newline to the end of the string). You should use .Write() instead if you want to achieve this functionality.

[hussain_ahmed]

int a;
for(a=0;a<=10;a++)
{
listbox1.items.add(a.tostring());
}

[thines01]

Yes, just put it next to it.
Are you using Visual Studio to edit your code?

using System;

namespace DW_409292_CS2_CON
{
   class Program
   {
      static void Main(string[] args)
      {
         Console.WriteLine("Enter a number");
         string strData = Console.ReadLine().Trim();
         int intData = 0;

         if (!int.TryParse(strData, out intData))
         {
            Console.WriteLine("Invalid number: " + strData);
            return;
         }

         Console.WriteLine(intData.ToString() + " is a nice number");
      }
   }
}
