用VB.NET中的值创建哈希表

hashtable .net-2.0 vb.net

是否可以用值创建一个“预填充”哈希表?

也就是说,类似于:

dim myHash as new Hashtable() = {"key1", "value1", "key2", "value2" }

首先,哈希表已经过时了。使用 Dictionary(Of TKey, TValue) collection initializer 语法:

Dim myDict As New Dictionary(Of Integer, String) From {{1, "One"}, {2, "Two"}}

Function CreateDictionary() As Dictionary(Of Integer, String)
    Dim d As New Dictionary(Of Integer, String)
    d.Add(1, "One")
    d.Add(2, "Two")
    Return d
 End Function

Dim myDict As Dictionary(Of Integer, String) = CreateDictionary()

Function CreateHashtable() As Hashtable
  Dim table = new HashTable()
  table.Add("key1", "value1")
  table.Add("key2", "value2")
  return table
End Function

Dim myHash As Hashtable = CreateHashtable()
