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? 🙂
