.SYNOPSIS Converts MemoryStream to a base64 encoded string. .DESCRIPTION Converts MemoryStream to a base64 encoded string. .PARAMETER MemoryStream A MemoryStream object for conversion. .PARAMETER Encoding The encoding to use for conversion. Defaults to UTF8. Valid options are ASCII, BigEndianUnicode, Default, Unicode, UTF32, UTF7, and UTF8. .EXAMPLE $string = 'A string' $stream = [System.IO.MemoryStream]::new() $writer = [System.IO.StreamWriter]::new($stream) $writer.Write($string) $writer.Flush() ConvertFrom-MemoryStreamToBase64 -MemoryStream $stream QSBzdHJpbmc= .EXAMPLE $string = 'A string' $stream = [System.IO.MemoryStream]::new() $writer = [System.IO.StreamWriter]::new($stream) $writer.Write($string) $writer.Flush() $stream | ConvertFrom-MemoryStreamToBase64 QSBzdHJpbmc= .EXAMPLE $string1 = 'A string' $stream1 = [System.IO.MemoryStream]::new() $writer1 = [System.IO.StreamWriter]::new($stream1) $writer1.Write($string1) $writer1.Flush() $string2 = 'Another string' $stream2 = [System.IO.MemoryStream]::new() $writer2 = [System.IO.StreamWriter]::new($stream2) $writer2.Write($string2) $writer2.Flush() ConvertFrom-MemoryStreamToBase64 -MemoryStream $stream1,$stream2 QSBzdHJpbmc= QW5vdGhlciBzdHJpbmc= .EXAMPLE $string1 = 'A string' $stream1 = [System.IO.MemoryStream]::new() $writer1 = [System.IO.StreamWriter]::new($stream1) $writer1.Write($string1) $writer1.Flush() $string2 = 'Another string' $stream2 = [System.IO.MemoryStream]::new() $writer2 = [System.IO.StreamWriter]::new($stream2) $writer2.Write($string2) $writer2.Flush() $stream1,$stream2 | ConvertFrom-MemoryStreamToBase64 QSBzdHJpbmc= QW5vdGhlciBzdHJpbmc= .OUTPUTS [String[]] .LINK http://convert.readthedocs.io/en/latest/functions/ConvertFrom-MemoryStreamToBase64/ #> function ConvertFrom-MemoryStreamToBase64 { [CmdletBinding(HelpUri = 'http://convert.readthedocs.io/en/latest/functions/ConvertFrom-MemoryStreamToBase64/')] param ( [Parameter( Mandatory = $true, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)] [ValidateNotNullOrEmpty()] [System.IO.MemoryStream[]] $MemoryStream, [ValidateSet('ASCII', 'BigEndianUnicode', 'Default', 'Unicode', 'UTF32', 'UTF7', 'UTF8')] [String] $Encoding = 'UTF8' ) begin { $userErrorActionPreference = $ErrorActionPreference } process { foreach ($m in $MemoryStream) { try { $string = ConvertFrom-MemoryStreamToString -MemoryStream $m ConvertFrom-StringToBase64 -String $string -Encoding $Encoding } catch { Write-Error -ErrorRecord $_ -ErrorAction $userErrorActionPreference } } } } |
