When we do code in c#, we have using statement to dispose our objects. so we don’t have to. :). What about PowerShell? Can we do that?
Here is a PowerShell function which behaves as using statement. 🙂
| Function Using-Object( | |
| [System.IDisposable] | |
| $InputObject, | |
| [scriptblock] | |
| $ScriptBlock = {throw "ScriptBlock is mandatory, please provide a value."}) | |
| { | |
| try | |
| { | |
| . $ScriptBlock | |
| } | |
| finally | |
| { | |
| if ($null -ne $InputObject -and $InputObject -is [System.IDisposable]) | |
| { | |
| $InputObject.Dispose() | |
| } | |
| } | |
| } |
So whenever we are dealing with an object that should be disposed we can use this function as below.
| # $Connection object will be diposed. | |
| Using–Object($Connection = New-Object System.Data.SQLClient.SQLConnection($ConnectionString)) { | |
| #code goes here. | |
| } |
Isn’t that cool? 🙂
