Thread Limitation for Parallel.For?

Question

My question is is there any way that we can limit the number of threads when we use the Parallel.For loop.

Suppose my machine has I3 processor and capable running 4 processes at a time. so when i run the Parallel.For loop in my machine, there will be 4 threads running in the background.

Is there any way to limit the number of threads?

You can use ParallelOptions with MaxDegreeOfParallelism = 4

 Parallel.ForEach(words, 
                  new ParallelOptions {
                        MaxDegreeOfParallelism = 4
                        }, 
                  s => DoAction(s));
