密钥在指定状态下无效 - 找不到接受参数“+”的位置参数

Question

我试图理解这个错误的实际含义。我是 PowerShell 新手，无法 弄清楚这个。我搜索过类似的问题，但内容与我的不同 要求。

简而言之，该脚本正在向数据历史系统查询批次/批号和 该批次的开始时间。 该脚本将使用任务计划程序每分钟运行一次。这还没有像我一样设置 仍处于测试阶段。 我已经设置了一个服务帐户，以便脚本运行。其详细内容是 存储在 cred 文件中。 该脚本使用该批次/批号创建一个文件夹。 该脚本创建一个日志文件，其中包含批次编号以及批次的开始日期和时间。 然后，当从服务器上载文件时，脚本会搜索服务器上的源文件夹。 工厂车间到源文件夹中脚本将文件移动到已创建的文件夹中 具有正确的批号。 如果文件超出批次开始和结束时间，则文件将移至无批次 将在其中手动审核它们的文件夹。

我已经完成了测试，手动将文件添加到服务器上的源文件夹中，并且 一切正常，但没有得到“找不到接受的位置参数” 脚本中的参数“+”。

我正在研究服务器配置和权限级别，但据我所知，什么也没有 已经改变了。我看不出脚本有什么问题，但希望有人可以给我 一些指示。

错误代码如下

如果对此类问题有疑问，请将其全部或部分包含在“$()”表达式中。

代替：

$x =“22”+“11”

尝试

$x = $([字符串]"22" + [字符串]"11")

PowerShell 有时会认为您尝试将 33 添加 22+11 而不是“2211”
