需要帮助 gui 后台作业双跃点问题和脚本冻结

问：

我遇到了后台作业的双跳脚本块问题，该脚本块要么不执行任何操作，要么冻结脚本。下面有说明。 该脚本的想法是获取文件列表（非常大的计数，~200k），然后以三种单独的方式处理它们（获取哈希码并获取真正的重复项，比较文件名并获取伪重复项，获取零长度文件）。目前，我正在研究哈希值。的结果是无法通过管道传递到的字符串（数组？）。这会导致遍历每个字符串以获取哈希值。当后台作业在脚本块和循环组件上工作时，会创建一个双跃点。我已经通过在作业脚本块中结合使用方法解决了这个问题。不幸的是，这冻结了表格。我问你的问题如下。如何强制结果为类型，或者如何在 Invoke-command 进行时解冻脚本？$job1get-filehash$job2foreachscriptblockinvoke-command[scriptblock]::Create()$job1system.io.fileinfo
