Argument is not used in format string
<p>Hey guys I'm sure if this had been asked already, but I could not find it. If it's redundant I'm sorry. Please link me to it. My question is:</p>

<p>What does error "Argument is not used in format string" mean? 
I am using C#</p>

<pre><code>using System;

class PrintNum
{


    static void Main()
    {

        short s = 10;
        int i = 1000;
        long l = 1000000;
        float f = 230.47f;
        double d = 30949.374;


        //This is where I'm getting the error. 
        Console.Write("s: %d\n", s); //&lt;&lt;&lt; if you hover over the variable s on the outside.
        Console.Write("i: %d\n", i);
        Console.Write("l: %ld\n", l);
        Console.Write("f: %.3f\n", f);
        Console.Write("d: %.3f\n", d);

    }
}
