powershell-2.0

问题 I've been using add-type in Powershell to dynamically compile in some C# classes I want to use. Works great except it's 2.0 only. I just discovered the -language csharpversion3 option, but it does not work with -path . How can I work around this? [Edit: removed bit about ReadAllText - I was mistaken.] 回答1: Here's the workaround: read the file as text. $script = [io.file]::readalltext($scriptpath) add-type $script -lang csharpversion3 I might as well paste in the rest and make this answer

问题 Documentation states: Adds a user-defined custom member to an instance of a Windows PowerShell object. What "Windows PowerShell object" stands for? This works fine: $obj = new-object system.object $obj | add-member -membertype noteproperty -name Name -value "OK" $obj.name But this does not: $obj = @{} Actually, I am trying to add property to $error[0]. 回答1: PowerShell has what's called a PSObject that is a wrapper around any .NET object (or it can be a totally custom object) and when you call

问题 I am writing a script for my site that utilizes a JSON configuration file. The JSON is similar to the following: "Groups": { "GroupOne": { "NamingFilter": { "Not":"<SITE>-MJ*", "Has":"*WM,*WT" } }, "GroupTwo": { "NamingFilter": { "Has":"<SITE>-MJ*, *WC,*WL" } }, "GroupThree": { "NamingFilter": { "Not":"<SITE>-MJ*", "Has":"*WI" } } } To convert the object to something PowerShell can read, I use ConvertFrom-Json which converts it to type PSCustomObject .

问题 I wrote a little powershell function that executes Get-EventLog against remote servers. On some servers this seems to just hang and never times out. Can I timeout a powershell function call?
