问题 Why does $dlls.Count return a single element? I try to declare my array of strings as such: $basePath = Split-Path $MyInvocation.MyCommand.Path $dlls = @( $basePath + "\bin\debug\dll1.dll", $basePath + "\bin\debug\dll2.dll", $basePath + "\bin\debug\dll3.dll" ) 回答1: You should use something like: $dlls = @( ($basePath + "\bin\debug\dll1.dll"), ($basePath + "\bin\debug\dll2.dll"), ($basePath + "\bin\debug\dll3.dll") ) or $dlls = @( $($basePath + "\bin\debug\dll1.dll"), $($basePath + "\bin\debug

问题 How can I determine the OS type, (Linux, Windows) using Powershell from within a script? The ResponseUri isn't recognised when this part of my script is ran on a Linux host. $UrlAuthority = $Request.BaseResponse | Select-Object -ExpandProperty ResponseUri | Select-Object -ExpandProperty Authority So I want an If statement to determine the OS type that would look similar to this: If ($OsType -eq "Linux") { $UrlAuthority = ($Request.BaseResponse).RequestMessage | Select-Object -ExpandProperty

问题 I use powershell as shell in Windows. When I'm trying to launch some application who's dll dependencies are missing in PATH environment variable, then nothing happens, powershell just silently returns with new command prompt. Is there a way to make powershell fail louder, telling me what exactly is missing, like default cmd shell does? 回答1: I was having this same problem. PowerShell was setting $LASTEXITCODE code to -1073741515 ( 0xC0000142 , 3221225794 ) but no output explaining what was

问题 I want to zip two arrays, like how Ruby does it, but in PowerShell. Here's a hypothetical operator (I know we're probably talking about some kind of goofy pipeline, but I just wanted to show an example output). PS> @(1, 2, 3) -zip @('A', 'B', 'C') @(@(1, 'A'), @(2, 'B'), @(3, 'C')) 回答1: There's nothing built-in and it's probably not recommended to "roll your own" function. So, we'll take the LINQ Zip method and wrap it up. [System.Linq.Enumerable]::Zip((1, 2, 3), ('A', 'B', 'C'), [Func[Object

问题 I'm trying to get the Database name from a connection string in PowerShell. "Server=server\instance;uid=User;pwd=Hello;Database=SomeName;" I can think of two ways to do that, either to search for the string Database , up until the first ; after that split the string on = and select the Databasename - but I don't really know how to do that. The second way could be with the DBConnectionStringBuilder like this: $sb = New-Object System.Data.Common.DbConnectionStringBuilder $sb.set

问题 PowerShell has a pretty good built-in help system that I use a lot and I'm able to see all help options with Get-Help * and query Cmdlets or can look up Topics with Get-Help about_* and then say Get-Help about_compar* to open the Comparison Operators topic which is all very good. However, I was trying to find how to get help on the various string operators, like .replace, .compare, .split, .substring. Does anyone know how to pull these topics up on the PowerShell console (possibly, they might
