Foreach - 并行对象

最近我们开始编写需要很长时间才能完成的脚本。因此我们深入研究了 PowerShell 工作流程。阅读一些文档后，我了解了基础知识。但是，我似乎找不到一种方法来创建[PSCustomObject]对于一个内的每个单独的项目foreach -parallel陈述。

一些代码来解释：

Workflow Test-Fruit {

    foreach -parallel ($I in (0..1)) {

        # Create a custom hashtable for this specific object
        $Result = [Ordered]@{
            Name  = $I
            Taste = 'Good'
            Price = 'Cheap'
        }

        Parallel {
            Sequence {
                # Add a custom entry to the hashtable
                $Result += @{'Color' = 'Green'}
            }

            Sequence {
                # Add a custom entry to the hashtable
                $Result += @{'Fruit' = 'Kiwi'}
            }
        }

        # Generate a PSCustomObject to work with later on
        [PSCustomObject]$Result
    }
}

Test-Fruit

出错的部分是为$Result哈希表中的Sequence堵塞。即使尝试以下操作，它仍然失败：

$WORKFLOW:Result += @{'Fruit' = 'Kiwi'}

好吧，就这样，经过尝试和测试：

Workflow Test-Fruit {

    foreach -parallel ($I in (0..1)) {

        # Create a custom hashtable for this specific object
        $WORKFLOW:Result = [Ordered]@{
            Name  = $I
            Taste = 'Good'
            Price = 'Cheap'
        }

        Parallel {

            Sequence {
                # Add a custom entry to the hashtable
                $WORKFLOW:Result += @{'Color' = 'Green'}
            }

            Sequence {
                # Add a custom entry to the hashtable
                $WORKFLOW:Result += @{'Fruit' = 'Kiwi'}
            }


        }

        # Generate a PSCustomObject to work with later on
        [PSCustomObject]$WORKFLOW:Result
    }
}

Test-Fruit

您应该将其定义为 $WORKFLOW:var 并在整个工作流程中重复使用以访问范围。
