        public static TypeInfo GetTypeInfo(this Type type)
        {

    }
}

I was getting some null reference exceptions on the GetDeclaredProperty call, so I refactored it and the exceptions stopped, just in case i added a try catch :)
Hope it helps, i'm new on this github thing so I won't contribute oficially yet, lol

public static object GetPropertyValue(this Object instance, string propertyValue)
{
try
{
PropertyInfo pi = instance.GetType().GetTypeInfo().GetDeclaredProperty(propertyValue);
return pi != null ? pi.GetValue(instance) : null;
}
catch
{
return null;
}
}
