I am implementing an application which requires the storage of a large
number of items in a cache.
I have 3-tuple key reprented by a struct, as well as an n-tuple (n is
fixed) dataset, also represented by a struct. At run time, I will no
exactly the number of items in the hashtable (I will have populated it
myself by loading the data from a database). During the course of the
applications lifetime, I will retrieve data in the hashtable...

Once a day or so, I receive an error on a fairly active website that
calls this StrMixed.cs method constructor. 99% of the time there is no
exception:

I'm seeing what looks like a leak with Hashtable, but guessing it is
something I'm doing -
void func1()
{
Hashtable hash = getHash();
//Loop thru assorted data, check to see if data exists as key in
hashtable.

Hi,
I am using a System.Windows.Forms.Label object as key in my Hashtable. One
thing that has surprised me is that if I create two Label objects with same
properties (ie. Name, TabIndex,Text,Size,Dock) and use them as Key in my
Hashtable it doesn't give any error.
I thought, generally, in a Hashtable we cannot use two same objects as keys.
The Label Objects in this case are being created in a loop and used as keys
in a Hashtable.

Hi!
What i want to do, is to put an ArrayList into a Hashtable. So i can access
the ArrayList fast over the key-indexing of the Hashtable.
What i did is to put the ArrayList into the Hashtable
hash = arraylist

How do I go about looping through a hash table and removing items. I know
how do this in a collectionbase, but can't iterate through the hash table
with out getting an error.
Here is my sample code for a collection base
for(int i = this.Values.Count; i > 0 ; i--)
{
//Set local object

Hi!
I'm kinda stuck here.
I have an Hashtable with with my custom "Item" Object. The key used in
the Hashtable is the "Item.Id", i have selected this key because with
a lot of functions i can get the right object from the hashtable
really fast. But now i need a function whom can get an object from the
hashtable based on the values each "Item" object holds.
("Item.ColorId","Item.SizeId","Item.OtherId"), but i can't identify
the object...

Is it possible to create a hashtable that doesn't store the key? I have a very large
hashtable and I just want it to store the HashCode and the Value (two Int16s).
Thanks - JackRazz

Hello.
I have a Hashtable, to which I insert key and values.
When I go over the hashtable with "foreach" later on,
the items are not coming out at the order I inserted them.
A quickwatch showed that as the items are inserted, they are not arranged in
the hash at the order they were inserted by.
Is there a way to control that with a hashtable ? I can't even sort it...
Thanks

Hello,
I´ve implemented a Hashtable with Int-Keys and Double Values.
Now I want to get the i-th Int-Key of my hashtable.
How do I do that?
I tried it like that:
ICollection intKeys = myHashtable.Keys;

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
