C# - Console.WriteLine() does not showing the second Parameter
<p>While working on the C# Basic datatypes when I made 2 bool variables using different methods and as I tried to show them using Console.WriteLine() method, first variable was displayed but 2nd one did't display. 
I know the alternates to get the desired output by just using the + symbol between variables or using Placeholder syntax in Console.WriteLine,but I just want to know the reason, why the 2nd parameter is not showing ? If someone know the reason do answer.</p>

<p>this is the code that I'm working on.  </p>

<pre><code>        bool b1 = true;
        System.Boolean b2 = new System.Boolean();
        b2 = false;
        Console.WriteLine( b1.ToString() , b2.ToString() );
</code></pre>
