Hashtable

The Hashtable contains items in key/value pairs.
The keys are used as indexes,and very quick searches can be made for values by searching through their keys.


Following is the sample code for create Hashtable

Sub Page_Load
if Not Page.IsPostBack then
  dim MyLanguage=New Hashtable
  MyLanguage.Add("T","Tamil")
  MyLanguage.Add("E","English")
  MyLanguage.Add("M","Malayalam")
  MyLanguage.Add("K","Kannada")

  rbList.DataSource=mycountries
  rbList.DataValueField="Key"
  rbList.DataTextField="Value"
  rbList.DataBind()
end if
end sub

sub displayMessage(s as Object,e As EventArgs)
  lblone.text="Your favorite Language is: " & rbList.SelectedItem.Text
end sub
