PowerShell Example¶

The DotCMIS DLL can be used in PowerShell scripts. Here is a simple example.

# load DotCMIS DLL
[Reflection.Assembly]::LoadFile("X:\path\to\DotCMIS.dll")


# -----------------------------------------------------------------

# helper functions
function New-GenericDictionary([type] $keyType, [type] $valueType) {

   $ct = $base.MakeGenericType(($keyType, $valueType))  
   New-Object $ct
}

function New-ContentStream([string] $file, [string] $mimetype) {
   $fileinfo = ([System.IO.FileInfo]$file)
   
   $contentStream = New-Object "DotCMIS.Data.Impl.ContentStream"
   $contentStream.Filename = $fileinfo.Name
   $contentStream.Length = $fileinfo.Length
   $contentStream.MimeType = $mimetype
   $contentStream.Stream = $fileinfo.OpenRead()
   
   $contentStream
}

function Download-ContentStream([DotCMIS.Client.IDocument] $document, [string] $file) {
   $contentStream = $document.GetContentStream()   
   $fileStream = [System.IO.File]::OpenWrite($file)

   $buffer = New-Object byte[] 4096  
   do {  
      $b = $contentStream.Stream.Read($buffer, 0, 4096)  
      $fileStream.Write($buffer, 0, $b)  
   }  
   while ($b -ne 0)
   
   $fileStream.Close()
   $contentStream.Stream.Close()
}
