最近我们开始处理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,我似乎找不到创建 [PSCustomObject]
的方法。对于 foreach -parallel
中的每个单独项目陈述。
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
出错的部分是给
$Result
添加一个值来自 Sequence
内的哈希表堵塞。即使尝试以下操作,它仍然失败:$WORKFLOW:Result += @{'Fruit' = 'Kiwi'}
最佳答案
好的,你去吧,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。
