Start-Process Variables In -ArgumentList
提问by Jamie
I was wondering if someone with more expertise could help me with a little problem I'm having with using Variables in -ArgumentListwhen using Start-Process.
我想知道是否有更多专业知识的人可以帮助我解决在-ArgumentList使用Start-Process.
If I run the Exe without using Start-Process
如果我在不使用的情况下运行 Exe Start-Process
.\DeploymentServer.UI.CommandLine.exe register --estNumber $Number --postcode $PostCode --password $Password
everything works fine, the command runs and the software is registered.
一切正常，命令运行，软件注册。
If I try
如果我尝试
Start-Process .\DeploymentServer.UI.CommandLine.exe -ArgumentList "register --estNumber $Number --postcode $PostCode --password $Password" -Wait -NoNewWindow
or
或者
$Arguments = "register --estNumber $Number --postcode $PostCode --password $Password"
Start-Process .\DeploymentServer.UI.CommandLine.exe -ArgumentList $Arguments -NoNewWindow -Wait
the command runs but is unable to register, stating that it can not match the details provided. So I'm assuming the issue lies either in the passing of the arguments to Start-Process, or -ArgumentListinterpreting the variables in the string. Am I missing something really simple here? Possibly to do with the $in the -ArgumentList?
该命令运行但无法注册，说明它无法匹配提供的详细信息。所以我假设问题在于将参数传递给Start-Process，或者-ArgumentList解释字符串中的变量。我在这里错过了一些非常简单的东西吗？可能与$中的有关-ArgumentList吗？

You have a space in your $postcode, so you need to put the argument in quotes:
您的 中有一个空格$postcode，因此您需要将参数放在引号中：
Start-Process .\DeploymentServer.UI.CommandLine.exe -ArgumentList "register --estNumber $Number --postcode `"$PostCode`" --password $Password" -Wait -NoNewWindow

I encountered several posts online saying to wrap a Start-Process-ArgumentListargument containing spaces in 2 layers of doubles quotes, escaping the inner double quotes with a back tick `, but at least in the context I needed it, that didn't work. I found a conceptually similar solution which did work, however, i.e. a set of single quotes on the outside and a "traditional" backslash escape sequence on inner double quotes. I was guided to using this approach per this PowerShell issue post:
我在网上看到几篇帖子说将Start-Process-ArgumentList包含空格的参数包装在 2 层双引号中，用反勾号转义内部双引号，但至少在我需要它的上下文中，这是行不通的。然而，我发现了一个概念上类似的解决方案，它确实有效，即外部的一组单引号和内部双引号上的“传统”反斜杠转义序列。根据这个 PowerShell 问题帖子，我被引导使用这种方法：

This example works for me (running a PS Start-Processcommand from cmd.exe):
这个例子对我有用（Start-Process从运行 PS命令cmd.exe）：
C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.exe Start-Process -FilePath 'C:\Program Files (x86)\Example\Test.exe' -ArgumentList 'arg1','\"arg 2 w spaces\"','arg3'
