是否有可能定义的Parallel.For执行顺序？ [英] Is it possible to define the execution order in Parallel.For?

问题描述

// parameters.Count == 10
// actualFreeLicenses == 2
Parallel.For(0, parameters.Count, new ParallelOptions() 
                    {
                        MaxDegreeOfParallelism = actualFreeLicenses
                    }, i =>
                    {
                        ExternalProgram(i);
                    }
);

当我执行上述code我注意到的价值我传递给 ExternalProgram 方法是1和; 6，后2及7，后3及8 ...

When I execute the above code I notice that the value of i passed to the ExternalProgram method are 1 & 6, later 2 & 7, later 3 & 8 ...

如果我有14个参数和2个许可证，它总是推出1安培; 8，以后2及9 ...

If I have 14 Parameters and 2 licenses it always launch 1 & 8, later 2 & 9 ...

是否有可能定义顺序：先1安培; 2，后3及4等？

Is it possible to define order: first 1 & 2, later 3 & 4 etc?

推荐答案

如果您使用的是并行的，他们的执行顺序为关联，因此平行的不是。您应该使用顺序工作流如果订单与您有关。

If you are using Parallel the order in which they are executed is not of relevance therefore "Parallel". You should use a sequential workflow if the order is relevant for you.
