    razor and math functions with data from xml

    Hopefully this is a simple one...

    i have an xml chunk i am reading in with razor...

    <RangeShown lower="1" upper="11"/>

    all i want to do is subract lower from upper... but i am having issues casting the strings as numbers...

    so i get this...

    String upper = doc.SelectSingleNode("/SearchResults/RangeShown/@upper").Value;
      String lower = doc.SelectSingleNode("/SearchResults/RangeShown/@lower").Value;

    and i want to change them into ints so i can do some simple math..

    int upperLimit = upper;
      int lowerLimit = lower;
      int numPerPage =  upperLimit - lowerLimit;

    but the int statements for upperLimit and lowerLimit obviously error... please help me to understand razor better ;)

    I'm no razor guru, but if it is anything like regular C#, you should be able to do:

    int upperLimit = int.Parse(upper);

    and so on...

    yeah it was wierd... int.Parse() was not working -- throwing an error... however 

    Convert.ToInt32() worked great... grrrr

    Lovely :-)

    Maybe because of the capitalised "String" instead of "string".

    Anyways, good to know :)
