Plinq provides the possibility of parallel query processing. To process query operations in parallel, you only need to insert the asparallel method. But the problem occurs in parallel itself.

Because in parallel execution, a large amount of data can be processed at the same time, but it is not sure which data is processed first. Therefore, in the following example, if the asparallel method
