VB.NET HashMap equivalent
提问by Andrew
I'm trying to store a set of objects and I need to be able to access them in constant time based on a particular property of the objects. I was hoping to do this by adding the objects to a HashMap and using the property that I want to index by as the key. Is there a HashMap object in VB like in Java, or should I use something else?
我正在尝试存储一组对象，并且我需要能够根据对象的特定属性在恒定时间内访问它们。我希望通过将对象添加到 HashMap 并使用我想要索引的属性作为键来做到这一点。在 VB 中是否有一个 HashMap 对象像在 Java 中一样，或者我应该使用其他东西吗？
Update: Using VB 2010, .NET 4
更新：使用 VB 2010、.NET 4

Depending on your needs you could use a HashTableor a Dictionary.
根据您的需要，您可以使用HashTable或Dictionary。
like this:
像这样：
Dim dictionary As New Dictionary(Of String, Integer)
dictionary.Add("Dot", 20)
dictionary.Add("Net", 1)
dictionary.Add("Perls", 10)
dictionary.Add("Visual", -1)
Dim Hashtable As New Hashtable()
hashtable.Add("Area", 1000)
hashtable.Add("Perimeter", 55)
hashtable.Add("Mortgage", 540)
Have a look at thisand thisfor more usage examples.
UPDATE:
更新：
But, as @Konrad Rudolph says, its better to use a Dictionaryfor multiple reasons. (On .NET 2.0 and obove)
但是，正如@Konrad Rudolph 所说，Dictionary出于多种原因最好使用 a 。（在 .NET 2.0 及以上）
