Question

I’ve been searching everywhere and I need a solution that would let me add 200-300 jobs with a certain function THAT ACCEPTS parameters. I know about delegate and object as single parameter but I was hoping for something that would allow to queue the tasks each with different paramentars instead of object parametar only.

Any help would be greatly appreciated.

Answer 1

You can do something like this:

void MyMethod(int param)
{
    ....
}

...

ThreadPool.QueueUserWorkItem(_ => MyMethod(1));
ThreadPool.QueueUserWorkItem(_ => MyMethod(2));
ThreadPool.QueueUserWorkItem(_ => MyMethod(3));
...
ThreadPool.QueueUserWorkItem(_ => MyMethod(42));

Another option is to make MyMethod accept a parameter of type Object, and use the second overload of QueueUserWorkItem:

void MyMethod(object param)
{
    int value = (int)param;
    ....
}

...

ThreadPool.QueueUserWorkItem(MyMethod, 1);
ThreadPool.QueueUserWorkItem(MyMethod, 2);
ThreadPool.QueueUserWorkItem(MyMethod, 3);
...
ThreadPool.QueueUserWorkItem(MyMethod, 42);
