Top / Hashtable

キーのハッシュ コードに基づいて編成された、キー/値ペアのコレクションを表します。

サンプル 

Dim hash As New Hashtable()

' Add some elements to the hash table. There are no 
' duplicate keys, but some of the values are duplicates.
hash.Add("txt", "notepad.exe")
hash.Add("bmp", "paint.exe")
hash.Add("dib", "paint.exe")
hash.Add("rtf", "wordpad.exe")

' The Add method throws an exception if the new key is 
' already in the hash table.
Try
    hash.Add("txt", "winword.exe")
Catch
    Console.WriteLine("An element with Key = ""txt"" already exists.")
End Try

' The Item property is the default property, so you 
' can omit its name when accessing elements. 
Console.WriteLine("For key = ""rtf"", value = {0}.", hash("rtf"))

For Each de As DictionaryEntry In hash
    Console.WriteLine("Key = {0}, Value = {1}", de.Key, de.Value)
Next de
