它的错误处理可以通过以下方式进行: 使用ErrorAction参数:可以通过在Foreach-Object命令中使用ErrorAction参数来指定错误处理的行为。该参数有以下几个可选值: Stop:遇到错误时立即停止执行,并抛出异常。 Continue:遇到错误时继续执行后续的操作。 SilentlyContinue:遇到错误时忽略错误,继续执行后续的操作。 例
不妨称它为cmdlet-foreach 这一点区别将会在使用continue的时候显现出来 continue放在在某个Loop中时(比如foreach),那么它的行为就像c语言那样 如果是放在foreach-object(有时候简写为foreach,区分loop-foreach),充当scriptblock 这时候,会尝试跳过最近的loop语法层(如果存在的话) ...
在Foreach-Object中,没有直接的"break"语句来终止循环。但是,可以使用一些方法来实现类似的功能,例如使用标志变量或者引发异常。以下是一些示例: 使用标志变量: 代码语言:powershell 复制 $continue = $true $array = 1..10 foreach ($item in $array) { if ($item -eq 5 -and $continue) { $co...
continue } } $a | ForEach-Object { if ($_ % 2 -eq 0) { $_ } else { continue } } ...notice that only one set of multiples of 2 printed out. What happens in the ForEach-Object loop is that the first number passed into the loop is a 1 and when divided by 2, has a rem...
Terminating errors, such as exceptions, terminate the individual parallel instance of the scriptblocks in which they occur. A terminating error in one scriptblocks may not cause the termination of theForEach-Objectcmdlet. The other scriptblocks, running in parallel, continue to run unless they also...
ForEach-Objectis best used when sending data through the pipeline because it will continue streaming the objects to the next command in the pipeline, for example: ForEach-Object -InputObject (1..1E4) { $_ } | Measure-Object Count : 10000 ...
另外:可以由break, continue, throw 或return终止。在这些情况下,迭代器关闭。 let iterable = [10, 20, 30]; for (let value of iterable) { value += 1; console.log(value); } // 11 // 21 // 31 与for..in循环之间的区别: Object.prototype.objCustom = function() {}; ...
That is all there is to using theForeach-Objectcmdlet. Looping Week will continue tomorrow when I will talk about using theWhilestatement. I invite you to follow me onTwitterandFacebook. If you have any questions, send email to me atscripter@microsoft.com, or post your questions on theOff...
