c# 4.0 nullable input parameters to a method
<pre><code>public IQueryable&lt;Profile&gt; FindAllProfiles(string CountryFrom, string CountryLoc)
{
....
}
</code></pre>

<p>For the above method, is it possible to have nullable input parameters CountryFrom and CountryLoc? When I call this method, I have to pass in the 2 values otherwise I may get exceptions. Any ideas..?</p>
