-ArgumentList 中的启动进程变量

Question

I was wondering if someone with more expertise could help me with a little problem I'm having with using Variables in -ArgumentList when using Start-Process .

If I run the Exe without using Start-Process

.\DeploymentServer.UI.CommandLine.exe register --estNumber $Number --postcode $PostCode --password $Password

everything works fine, the command runs and the software is registered.

If I try

Start-Process .\DeploymentServer.UI.CommandLine.exe -ArgumentList "register --estNumber $Number --postcode $PostCode --password $Password" -Wait -NoNewWindow

or

$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 -ArgumentList interpreting the variables in the string. Am I missing something really simple here? Possibly to do with the $ in the -ArgumentList ?

您的$postcode有一个空格，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 -ArgumentList argument 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, ie 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:

This example works for me (running a PS Start-Process command from 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'
