title: C# Convert String to Integer
body: <p>I have finally taken the jump from VB.net to C# so I'm still having some issues.  I am making a simple weather app that connects through a RSS feed.  I want it to return a label that determines if it is freezing outside, however; I am having issues converting the temperature string to an integer so I can determine if the temperature is less than or equal to 32 degrees.  Any ideas?</p>
