    在VB.NET中有两种分支逻辑：函数和子程序，去区别在于函数能返回信息，而子程序不能。

    Sub name(parameters)
     code
    End Sub

    function name(parameters) as type
     code
     Return value
    end function

    sub Page_Load(obj as object, e as eventargs)
     code
    end sub


    <script runat="server">
      sub Page_Load(obj as object, e as eventargs)
     MultiplyNumbers(3,4)
     MultiplyNumbers(3,6)
      end sub


      sub MultiplyNumbers(intA as integer, intB as integer)
     Response.Wirte(intA*intB &<br>)
      end sub
    </script>


    可选参数 function MutliplyNumbers(intA as integer, optional intB as integer) as Integer
    <script runat="server">
      Class Clock
     public second as integer
     public minute as integer
     public hour as integer
     
     sub SetTime(intSec as integer, intMin as integer,intHour as as integer)
      Second = integer
      Minute = intMin
      hour = intHour
     end sub
      End Class

    </script>
