How do I calculate the maximum page index when paging in C#.NET?

using System;
 
public static class PagingUtility
{
    /// <summary>
    /// Calculates the maximum page index
    /// </summary>
    /// <param name="itemCount">Number of items to be paged</param>
    /// <param name="pageSize">Number of items on each page</param>
    /// <returns>Maximum page index (>=1)</returns>
    public static int MaximumPageIndex( int itemCount, int pageSize )
    {
        int returnValue = 1;
 
        if ( itemCount > 0 && itemCount > pageSize && pageSize > 0 )
        {
            returnValue = itemCount / pageSize;
 
            int remainder = itemCount % pageSize;
 
            if ( remainder > 0 )
            {
                returnValue++;
            }
        }
 
        return returnValue;
    }
}
