Here is a solution from Using-Object: PowerShell version of C#’s “using” statement which works by calling .Dispose() in a finally block:

function Using-Object
{
    [CmdletBinding()]
    param (
        [Parameter(Mandatory = $true)]
        [AllowEmptyString()]
        [AllowEmptyCollection()]
        [AllowNull()]
        [Object]
        $InputObject,

        [Parameter(Mandatory = $true)]
        [scriptblock]
        $ScriptBlock
    )

    try
    {
        . $ScriptBlock
    }
    finally
    {
        if ($null -ne $InputObject -and $InputObject -is [System.IDisposable])
        {
            $InputObject.Dispose()
        }
    }
}

And here's how to use it:

Using-Object ($streamWriter = New-Object System.IO.StreamWriter("$pwd\newfile.txt")) {
    $streamWriter.WriteLine('Line written inside Using block.')
}
