You should try first :)
Any how take idea from this.

main()
{
int result=0;
int num=0; // in this variable you have to take input from the user.
for(int i=1;i<=num;i++)
{

if(i%2==0)
{

result=result+i;

}
}

}

Well, I'll do this one for you but you really should try and do these yourself as they won't get any easier:

using System;

class Program
{
static void Main()
{
Console.Write ("Enter a positive number : ");
int number = int.Parse(Console.ReadLine());

int sum = 0;

for(int i = 1; i <= number; i++)
{
// if there's no remainder after dividing by two
// then the number is even
if (i % 2 == 0) sum += i;
}

Console.Write("The sum of the even numbers up to this number is : ");
Console.WriteLine(sum);
Console.ReadKey();
}
}
