Nested Parallel For case

Question

Hi,

 

Could you please help in solving the parallel loop problem, which I have attached. Create a windows form application and use this form1.cs file to the project. I run this in .NET framework 4.7.2.

 

Could some one check the case 4 and help me in solving the nested for loop with a parallel for loop.

 

FYI: Case 2 and Case 3 works.

 

Thanks,
