C#. Algorithm. Please Help. Thanks.

Develop an algorithm that initializes a vector( a list of numbers) of 5 positive numbers by requesting the input from the user. Check if all the numbers entered are multiples of 2 or 5, if they are, it communicates it in output to the user. Finally print the numbers in the reverse order of the entry.

don't ask full code, i am helping now ,but from now try to post portions where you feel stuck.

public static void Main()
{
List<int> nums = new List<int>();
int i=0;
Console.WriteLine("Enter 5 numbers");
while (i < 5)
{
var input=Console.ReadLine();
int y;
if (int.TryParse(input, out y))
{
if (y >= 0)
{
nums.Add(y);
}
else
{
Console.WriteLine("Number can not be a Negative integer");
}
}
else
{
Console.WriteLine("only numbers allowed");
}
i++;
}
Console.WriteLine("You have entered following numbers");
foreach (var num in nums)
{
Console.WriteLine(num);
}
Console.WriteLine("numbers in reverse order:");
nums.Reverse();
foreach (var num in nums)
{
Console.WriteLine(num);
}
Console.ReadLine();
}

Have you tried something? Seems like a homework and it is not possible to to the whole code for you. If you stuck somewhere, do let us know.
