Problem with c # stream

Question

I am trying to simplify the task as follows:

• I have about 100 files that I would like to read and then process the data.
• Why do I maintain an array of file names and locations
• I create streams to read files.

Now my problem is that I would like to make sure that only 5 threads appear at a time, since starting 100+ threads is not a good idea at all.

So, please tell me which approach should I use to ensure that only 5 threads work on time, and as soon as one of them is completed, a new one can be launched.

Thanks everyone

Answer 1

/Rx ( .NET 4.0, 3.5):

        var options = new ParallelOptions();
        options.MaxDegreeOfParallelism = 5;

        Parallel.ForEach(GetListOFiles(), options, (file) =>
        {
             DoStuffWithFile(file);
        });
