Download SharePoint 2010 Library Items using PowerShell V2 with CSOM - sharepoint-2010

Question

my goal is: Get the items within the folders in a SharePoint 2010 library. I'm struggling trying to get some Items from a SharePoint 2010 Library using CSOM with PowerShell.
I tried three different methods that i found in the internet but still without success. Also the Microsoft's Documentation is really sh*t in this aspect, hope somebody can help me. So here we go:
1.Method A
[Microsoft.SharePoint.Client.FileInformation]$fileInfo = [Microsoft.SharePoint.Client.File]::OpenBinaryDirect($ctx, $file.ServerRelativeUrl);
[System.IO.FileStream]$writeStream = [System.IO.File]::Open("$($libraryTargetPath)\$($file.Name)", [System.IO.FileMode]::Create);
$fileInfo.Stream.CopyTo($writeStream);
$writeStream.Close();
With the A method I get this error:
Method invocation failed because [System.Net.ConnectStream] doesn't contain a method named 'CopyTo'.
+ $fileInfo.Stream.CopyTo <<<< ($writeStream);
+ CategoryInfo : InvalidOperation: (CopyTo:String) [], RuntimeException
+ FullyQualifiedErrorId : MethodNotFound
The [System.Net.ConnectStream] can't find the method CopyTo
I was lookign information about this, in the System.Net namespace and in the "Microsoft.SharePoint.Client.FileInformation" class but without success :(
2.Method B
$binary = [Microsoft.SharePoint.Client.File]::OpenBinaryDirect($ctx, $file.ServerRelativeUrl)
$Action = [System.IO.FileMode]::Create
$new = "$($libraryTargetPath)\$($file.Name)"
$stream = New-Object System.IO.FileStream $new, $Action
$writer = New-Object System.IO.BinaryWriter($stream)
$writer.write($binary)
$writer.Close()
Method B don't give me a error, but in stead of downloading the Items, it makes empty files in the destination folder. So this method isn't downloading the items, just making new files.
3.Method C
$binary = $file.OpenBinary()
$stream = New-Object System.IO.FileStream("$($libraryTargetPath)\$($file.Name)"), Create
$writer = New-Object System.IO.BinaryWriter($stream)
$writer.write($binary)
$writer.Close()
I'm not sure if method C belongs to CSOM or to the SharPoint built-in Server side client, if it's so please let me know. This is the error i'm getting:
Method invocation failed because [Microsoft.SharePoint.Client.File] doesn't contain a method named 'OpenBinary'.
At C:\Users\Administrator\Desktop\SharePointOnPremisesBackUp\SharePointOnPremisesBackUp.ps1:77 char:31
+ $binary = $file.OpenBinary <<<< ()
+ CategoryInfo : InvalidOperation: (OpenBinary:String) [], RuntimeException
+ FullyQualifiedErrorId : MethodNotFound
And here PowerShell can't find the OpenBinary() method in Microsoft.SharePoint.Client.File and there is nearly not information about this method.
Here is the complete function I'm trying to use:
function GetDocumentLibs ($ctx, $web)
{
Function IterateFoldersRecursively([Microsoft.SharePoint.Client.Folder]$folder, [Microsoft.SharePoint.Client.ClientContext]$ctx)
{
# make sure that the "Web.Context.Url" is the current web url
if ($web.Context.Url.StartsWith($SiteCollectionUrl) -eq $true)
{
$files = $folder.Files
$ctx.Load($folder.Files)
$ctx.Load($folder.Folders)
$ctx.ExecuteQuery()
foreach ($subFolder in $folder.Folders)
{
IterateFoldersRecursively $subFolder $ctx
}
# Check if folder Exist and Skip
$libraryTargetPath = "$($TargetPath)\$($folder.ServerRelativeUrl.Replace('/', '\'))"
New-Item -Path $libraryTargetPath -ItemType Directory -Force
foreach ($file in $files)
{
# Method 1
[Microsoft.SharePoint.Client.FileInformation]$fileInfo = [Microsoft.SharePoint.Client.File]::OpenBinaryDirect($ctx, $file.ServerRelativeUrl);
[System.IO.FileStream]$writeStream = [System.IO.File]::Open("$($libraryTargetPath)\$($file.Name)", [System.IO.FileMode]::Create);
$fileInfo.Stream.CopyTo($writeStream)
$writeStream.Close()
# Method 2
$binary = [Microsoft.SharePoint.Client.File]::OpenBinaryDirect($ctx, $file.ServerRelativeUrl)
$Action = [System.IO.FileMode]::Create
$new = "$($libraryTargetPath)\$($file.Name)"
$stream = New-Object System.IO.FileStream $new, $Action
$writer = New-Object System.IO.BinaryWriter($stream)
$writer.write($binary)
$writer.Close()
# Method 3
$binary = $file.OpenBinary()
$stream = New-Object System.IO.FileStream("$($libraryTargetPath)\$($file.Name)"), Create
$writer = New-Object System.IO.BinaryWriter($stream)
$writer.write($binary)
$writer.Close()
# delete folder
}
}
}
$folder = $web.GetFolderByServerRelativeUrl($web.ServerRelativeUrl)
$ctx.Load($folder)
$ctx.ExecuteQuery()
IterateFoldersRecursively $folder $ctx
}
the tools I'm using:
Sapien's PowerShell Studio
PowerShell V2 with CSOM
SharePoint 2010 OnPremises
Please if you have any Solution, Reference, Documentation or tutorial that can be useful tell me. Thanks in advance.

Answer 1

After a lot of research i found a solution and decide to use this method:
function GetDocumentLibs ($ctx, $web)
{
$site = $ctx.Site
$ctx.Load($site)
$ctx.ExecuteQuery()
$siteUrl = $site.Url
Function IterateFoldersRecursively([Microsoft.SharePoint.Client.Folder]$folder, [Microsoft.SharePoint.Client.ClientContext]$ctx)
{
if ($web.Context.Url.StartsWith($SiteCollectionUrl) -eq $true)
{
$files = $folder.Files
$ctx.Load($folder.Files)
$ctx.Load($folder.Folders)
$ctx.ExecuteQuery()
foreach ($subFolder in $folder.Folders)
{
IterateFoldersRecursively $subFolder $ctx
}
$targetPath = "$($TargetPath)\$($folder.ServerRelativeUrl.Replace('/', '\'))"
New-Item -Path $targetPath -ItemType Directory -Force
foreach ($file in $files)
{
$client = new-object System.Net.WebClient
$client.UseDefaultCredentials = $true
$client.DownloadFile("$($siteUrl)$($file.ServerRelativeUrl)", "$($targetPath)\$($file.Name)")
}
}
}
$folder = $web.GetFolderByServerRelativeUrl($web.ServerRelativeUrl)
$ctx.Load($folder)
$ctx.ExecuteQuery()
IterateFoldersRecursively $folder $ctx
}
Remember to implement some exception handling.
I hope this is helpful for somebody with the same problem.
