    Associative Array

    I'm an ASP .Net newbie and need some help. Does ASP .NET support what I
    consider a "structure" or an "associativ e array"?

    I'm look for a data type that will hold a key name and a value such as this
    pseudo code below:

    Dim EmployeeInfoas (Structure or Associative Array?? What data type
    here???)

    'Add key and value:
    Employee.Add(<k ey>, <value>)
    Employee.Add("F ullName","John Smith")
    Employee.Add("P hone","555-5555")

    'And then be referenced in this type of manner:
    response.write( "Employee Name: " & Employee("FullN ame") & "<BR>")
    response.write( "Phone: " & Employee("Phone "))
    'Or maybe there's a "Get" method or something... like Employee.Get("P hone")

    and the web page would write out:

    Employee Name: John Smith
    Phone: 555-5555

    The point is I'd like to use a string value to identify an index in an
    array, not an integer. Can anyone point me in the right direction here? Is
    this even possible? Please advise.

    Thanks,
    -Joe

      Re: Associative Array

      You want a system.collecti on.hashtable

      or a system.collecti on.specialized. namevaluecollec tion

      the latter being used when the key and value are strings, the former for any
      type of object..

          Karl,

          Thanks very much for the quick response... I'm just working with Strings so
          the latter should be great!

          Much obliged,
          -Joe
