How can I pass an int value as the LinkText for and ActionLink

@Html.ActionLink((string)item.NUM, "Building", "Property", new {id=item.STRAP, bldNum = item.NUM }, null)
 

This throws a Yellow screen of death.

Cannot convert type 'int' to 'string'

However, this works.

@Html.ActionLink("HI", "Building", "Property", new {id=item.STRAP, bldNum = item.NUM }, null)
