Output a PowerShell object into a string
提问by johnnycrash
This code launches ping:
此代码启动 ping:
$ProcessInfo = New-Object System.Diagnostics.ProcessStartInfo
$ProcessInfo.FileName = "ping.exe"
$ProcessInfo.RedirectStandardError = $true
$ProcessInfo.RedirectStandardOutput = $true
$ProcessInfo.UseShellExecute = $false
$ProcessInfo.Arguments = "localhost"
$Proc = New-Object System.Diagnostics.Process
$Proc.StartInfo = $ProcessInfo
$Proc.Start() | Out-Null
When I type $Proc at the command,
当我在命令中输入 $Proc 时,
$Proc
I get this:
我明白了:
Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id ProcessName
------- ------ ----- ----- ----- ------ -- -----------
27 3 1936 1852 10 0.02 6832 PING
I want to get the data line into a string.
我想把数据行变成一个字符串。
So I tried this:
所以我试过这个:
$Proc | Format-table -HideTableHeaders
And I got this:
我得到了这个:
27 3 1936 1852 10 0.02 6832 PING
I tried this:
我试过这个:
$Foo = $Proc | Format-table -HideTableHeaders
$Foo
And got this:
得到了这个:
Microsoft.PowerShell.Commands.Internal.Format.FormatStartData Microsoft.PowerShell.Commands.Internal.Format.GroupStartData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.GroupEndData Microsoft.PowerShell.Commands.Internal.Format.FormatEndData
So the question is... How do you typically get the nice string output from a powershell object into a string?
所以问题是......您通常如何将来自 powershell 对象的漂亮字符串输出转换为字符串?
Ultimately all I'm trying to do is stick the word START in front of the normal output I get when I just type $Proc by itself on a line in my powershell script.
最终,我想要做的就是将 START 一词贴在我在 powershell 脚本的一行中单独键入 $Proc 时得到的正常输出前面。
START 27 3 1936 1852 10 0.02 6832 PING
But, "Start " + $Proc produces this:
但是, "Start " + $Proc 产生这个:
Start System.Diagnostics.Process (PING)
So that's why I thought I'd try to get $Proc into a string.
所以这就是为什么我想我会尝试将 $Proc 放入一个字符串中。

Something like..
就像是..
$string = $proc | Format-Table -HideTableHeaders | Out-String
"start" + $string
