使用Powershell发送邮件时电子邮件正文被切断

所以我有一个PS脚本，我用它来检测计算机正在使用什么显示器。目标是通过RMM服务在客户端的计算机上远程运行这些脚本，以便在不联系客户端的情况下获取这些信息。为了获得输出，我想通过电子邮件将信息发送给自己。我设法获得了一封要发送的电子邮件，但与Powershell中显示的输出相比，电子邮件的正文被切断。我使用$body变量打印到命令行和电子邮件正文，因此它们应该是相同的，但它们不是。有人看到我的代码有什么问题吗（除了为了隐私而删除的电子邮件信息）

编辑：我试着对[$body+=“`n$Name，$Serial”]行进行注释，如果跳过了这一部分，电子邮件就可以正常发送。Cpt。Whale建议它与``n字符有关，但在我使用它的其他地方，它工作得很好。所以我认为ForEach循环的第二次迭代出了问题，但是我没有足够的PS经验来知道它可能是什么。

所有这些都考虑到了。这是非常谨慎/有价值的，将代码块作为单个任务进行一步，以确保您在进入下一步之前得到预期的结果

例如，单步执行您的操作，使用PowerShell变量压缩将结果分配给变量，同时将结果输出到屏幕，以便实时监控正在发生的事情以及正在生成/传递的内容（我确实对您的代码进行了一些重构）：

如果您在文本编辑器中查看电子邮件，是否会看到正文内容没有显示？一个常见的问题是html格式不符合

`n

我编辑了我的问题。所以我不明白为什么会是``n字符，因为我在多行中使用它，如果我在ForEach循环中注释掉[$body+=“`n$Name，$Serial”]，它们会正确显示。这让我觉得在循环的第二次迭代中出现了一些问题，但我对powershell的了解还不够，无法知道它可能是什么。我运行了您的脚本，发现以下错误：“发送邮件：无法转换”System.Object[]参数“Body”所需的类型“System.String”。不支持指定的方法。在C:\PS\u Scripts\Monitor.ps1:140 char:18+Send-MailMessage@sendMailMessageSplat+~~~~~~~~~~~~~~~~~~~~~+CategoryInfo:InvalidArgument:（：）[Send-MailMessage]，ParameterBindingException+FullyQualifiedErrorId:CannotConvertArgument，Microsoft.PowerShell.Commands.SendMailMessage“另外，我的原始脚本没有复制任何内容，因此我不确定您为什么要将该“功能”添加到解决方案中。嗯，我没有测试Send MailMessage的内容，所以，嗯，好吧，但对于添加任何功能，我没有补充什么。然而，使用多监视器设置（我的包括一个4端口便携式显示端口），您将获得重复的信息（按照for循环，“$videooutput”中每个项目1个）。在单个监视器上进行此设置将不起作用。
