For Each Activity
Parallel For Each Activity
In this case
FOR EACH Activity
-Check the array in a queue
PARALLEL FOR EACH Activity
- After reading up on it, it can execute the iterations faster because they run in parallel.
For Each - Only the last image in the array will be monitored
Parallel For Each - Every image in the array will be monitored

- Iterations takes place sequentially, one by one
- foreach loop is run from a single Thread.
- foreach loop is defined in every framework of .NET
- Execution of slow processes can be slower , as they’re run serially
- Process 2 can’t start until 1 is done. Process 3 can’t start until 2 & 1 are done…
- Execution of quick processes can be faster , as there is no threading overhead
- Execution takes place in parallel way.
- Parallel.ForEach uses multiple Threads.
- Parallel.ForEach is defined in .Net 4.0 and above frameworks.
- Execution of slow processes can be faster , as they can be run in parallel
- Processes 1, 2, & 3 may run concurrently (see reused threads in example, below)
- Execution of quick processes can be slower , because of additional threading overhead
Here you go with an example
I understand what you mean to me.
But if you make an example and put it into practice,
It’s hard to tell the difference between for-each activity and parallel-for-each activity.
The result I imagined.
For 1 : 1
For 1 : 2
For 1 : 3
For 2 : 1
For 1 : 4
For 2 : 2
However, Parall For Each Activity 1, 2, and 3 do not interfere with each other while each is running.
It’s just like For Each Activity.
