powershell – Foreach -parallel对象

2023年1月24日 311次阅读

最近我们开始研究需要很长时间才能完成的脚本.因此我们深入研究了Power
Shell工作流程.阅读完一些文档后,我了解了基础知识.但是,我似乎找不到为foreach -parallel语句中的每个单独项创建[PSCustomObject]的方法.

一些代码解释：

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

出错的部分是在Sequence块中为$Result哈希表添加一个值.即使尝试以下操作,它仍然会失败：

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

最佳答案 好的,你去,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并重复使用整个工作流程来访问范围.
