C# | Better way of parsing string to boolean

At the moment I am using this to check a boolean property in sharepoint 2007 using C# and .Net Framework 3.5

if (bool.Parse(listItem.Properties["Boolean Property"].ToString()) == false)

is there any better way of doing it ?

Edit

when my code try to convert property into string it gives me exception even when am validating if property is empty or not.

This Worked For me

using method "Contains Key" instead of "Properties.Containsfield"

object abc = "bool property";

foreach (SPListItem item in list.Items)
{
     if (item.Properties.ContainsKey(abc)
