Hi
Can any one say how to check a hashtable by ignoring the case of key
supplied. I want the following requirement
It should not allow the user to do the following
Hashtable table = new Hashtable();
a) table.Add("one" ,1);
b) table.Add("One" ,1);
by default it executes the above two statements with out any
problem. But my intention is to throw an exception when the table contains
the key by ignoring the case. Is there any way to implement like above?
Thanks in advance

Srikanth,
What you want to do is call the constructor that takes an IComparer,
passing a CaseInsensitive Comparer instance. Then, when you call Add with
the same key, it will throw an exception.
It should be noted that particular constructor is marked as Obsolete in
..NET 2.0, in favor of a new interface (only available in 2.0).
Hope this helps.

You must convert keys to upper case (or lower case) before storing them...

That would require excessive maintinence. You can use a
CaseInsensitive Comparer (passed through the constructor) which would treat
the keys in a case-insensitive manner.

I'm looking for a way to step through a hashtable while adding items
to the table (This precludes using enumerators. They don't like
HashTable alterations while they are active). There must be an
internal structure that can be accessed sequentially, like an array.
Is it accessible?
Or maybe there is another construct that will allow this. The main
reason I'm using a HashTable is to eliminate duplicate entries.

I intended to save properties of an object to a Hashtable. In this case, keys and values are not fixed types and I cannot use SortedList.
I have no idea what order the .NET framework add items to Hashtable when Add(key, value) method is applied. Monitoring the position items are added, I cannot find if key is the standard or value.
I thought basically Hashtable function acts randomly, therefore the order will be changed unexpectedly.

Doing a project that makes heavy use of domain names such as

Domain names preserve case but are concidered equal if names are same but
case is different.
I know I can store these names as keys in a hashtable with case insens
comparer and CaseInsensitiveHashCodeProvider. That works fine. The benifit
is I can store the domain name and not worry about case and return the user
supplied case without storing an state, etc. ...

Hi all,
Using C# 1.1:
I need a fast way of determining whether a string is in a list of approx 150 keyword like strings.
in two versions: one case-sensitive, the other one case-insenstive.
I thought of loading the keywords in a Hastable as Keys with null values,
and then use Hastable.ContainsKey(string)
but Hashtable does not seem to support case-insentive keys.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
