Web Service and Hash Table

Hi Everyone -

Here is my question(s)

I have a web service that needs to keep a table in memory (hash table) and when a client connects

and requests a token, a GUID is generated and placed into the hash table and returned to the caller.

Is there a way to create this hash table in global memory (like a critical section) that can be used by

each instance of the web service client calling?

thanks

tony

Place it in Application memory.. You could simply cast it and read it back

when you are setting it .. place the hashtable in the application state bag as follows

Application["testTable"] = yourHashTable;

when you read simply cast the application state item into hashtable

if(Application["testTable"] != null)

{

Hashtable ht = (Hashtable)Application["testTable"];

}

Hi -

Thanks for a great answer...

application state bag... please elaborate on where this is created?

thanks

tony

This is created in the application memory.. to be precise, inside the appDomain memory space.. so its available for all the user sessions

Right - thanks for the additional response.

In code, where do i create the hash table?

thanks

tony

Since you are going to use the same hashtable through out your application.. you can create the hashtable in Application_Start event handler in Global.asax and use it wherver you add record or retrieve record
