- param( [System.IO.Stream]$reader, $fileName, $encoding = [System.Text.Encoding]::GetEncoding( $null ) )
- if($fileName) {
- $writer = new-object System.IO.FileStream $fileName, "Create"
- } else {
- [string]$output = ""
- }
- [byte[]]$buffer = new-object byte[] 4096
- [int]$total = [int]$count = 0
- do
- {
- $count = $reader.Read($buffer, 0, $buffer.Length)
- if($fileName) {
- $writer.Write($buffer, 0, $count)
- } else {
