.NET Forum / Languages / C# / March 2008Threads (handlers) issue
Hello, I got the following question , part of my future application I will run number of threads according to number of enteries in input xml file. How can I dynamically build handlers which will wait for those threads if I don't know before the runtime how many threads will be? Thank u! > I got the following question , part of my future application I will run > number of threads according to number of enteries in input xml file.

Consider how you'd do it if you knew to start with that you'd use 15 threads. Once you know that, it will probably be easy to take 15 and make it n.

As I said, work out how you'd handle it if you *do* know how many threads it'll be - taking 15 as an example - then adapt it so that you can pass in the number of threads as a parameter. What would you do with 15 threads?

Well, you still haven't said what you mean by a "handler", but yes you can create threads dynamically. It's not a problem so long as you work out what you actually want to do with the threads.

However, I *strongly* suggest you just write some prototype code with a fixed number of threads. I really think you'll find you just don't have the problem you're anticipating. Jon It's starting to sound like you want to study how to use the .NET Threadpool with the QueueUserWorkItem method and a callback. -- Peter Site: http://www.eggheadcafe.com UnBlog: http://petesbloggerama.blogspot.com Short Urls & more: http://ittyurl.net > My aim to create as much threads as will be in input and to get the > result for each one of them.
