The keys and values associated with the hash table are:<\/p>\n

PS C:> $d\n <\/p>\n

—-                           —–                                          <\/p>\n

c                              30                                             <\/p>\n

b                              29                                             <\/p>\n

a                              28          <\/p>\n

You can retrieve by name (key) property by using the item method or by directly supplying the key.<\/p>\n

  Note <\/b> Key names are letters, and to retrieve via the names, you must enclose the letters in quotation marks.<\/p>\n
