Need the fastest algorithm for this small program

Thanks Sandeep for quick respond.Actually i am new at the C# here is my full code:

static void Main(string[] args)
        {
            int n = 1;
            while (n <= 75)
            {
                if (n % 5 == 0)
                    System.Console.WriteLine("Foo");
                else if(n%7==0)
                    System.Console.WriteLine("Bar");
                else if (n%5==0 && n % 7 == 0)
                    System.Console.WriteLine("FooBar");
                else
                    System.Console.WriteLine(n);
                n++;
            }

It print correctly for number divisible by 5 and 7 but it print "Foo" for number is divisible my both 5 and 7.SO can you tell me what is wrong with code.As i am new to C# and is this is the fastest algorithm for this program.

A bit smaller and faster:

void Solution3()
        {
            for (int n = 1; n <= 75; n++)
            {
                if (n % 35 == 0)
                    Console.WriteLine("FooBar");
                else if (n % 5 == 0)
                    Console.WriteLine("Foo");
                else if (n % 7 == 0)
                    Console.WriteLine("Bar");
                else
                    Console.WriteLine(n);
            }
        }

Greetings!

for(int i=0;i<75;i++)
{if(n%5==0)
  print"foo"
 if(n%7==0)
  print "bar"
 else print i;
}
