Hello,

I wanted to know if there was any other (or faster) way to access data in a hashtable besides using a foreach?

Thanks,

Tim

Let's say dict is your dictionary and key is the key. You can get data associated with key this way:

C#:
string data = dict[key];

VB:
Dim data As String = dict(key)

EDIT: You can also use TryGetValue if you're not sure whether the key exists in the dictionary or it doesn't.

EDIT2: And I was thinking of a Dictionary, not a HashTable, sorry for that :). HashTable works the same way except you have to cast the output to the correct type:

C#:
string data = (string)dict[key];

VB:
Dim data As String = DirectCast(dict(key), String)

Hi Tim,

check out the System.Collections.Hashtable.ContainsKey() and System.Collections.Hashtable.ContainsValue() method.

I've looked at these but it doesn't seem to get me exactly what I want. Let's say I have an hashtable with int's as the keys associated with different strings. If I have one of the keys, what's the best way to find the string associated with the key (while loop using IDictionaryEnumeration, foreach loop, etc.).

Very helpful. Thanks a lot ...
