Why can't I return only in a nested body of my Method and not be forced to return in the scope of the main method?
<p>Why is it that if you declare a return type on a method, that you have to specify a return in the scope of that method? Meaning, if I have a If/Switch in my method I can't specify the return there "ALONE" and not in the main method body? Is the only way around this is to assign the value returned by the nested procedure to a variable and return the variable in the main body of the method?</p>

<p>Example:</p>

<pre><code>public Int GetNum()
{
   var a = 1;
   switch(a)
   {
      case 1:
        return 1 + 5;
      default:
        return a;
   }
 return a;   //Why must I specify this return if it is going to hit my switch statement
             //and return some int.
}
</code></pre>
