How lock files with Google drive API V3 in VB.NET

Hi to all, can someone share an example to how lock/unlock/check if a file is locked inside Google Drive ?

I saw the example in Python but I'm not able to create a correct routine to do it in VB.net

That's the examples in Python: https://developers.google.com/drive/...s/file-locking

and this is my routine
If FileID <> "" Then
Dim file As Google.Apis.Drive.v3.Data.File = Service.Files.Get(FileID).Execute
Dim metadata = New Google.Apis.Drive.v3.Data.File()
metadata.Description = "Test01"
metadata.ContentRestrictions = ' I want to set to read only
Service.Files.Update(metadata, FileID).Execute()
End If


Can someone Help me ?

@acturus999:
While this doens't answer your question, here are a few tips:
1. Use code tags (the "#" button above the message you're about to post) to enclose your code.
2. Another way to write "If FileID <> "" Then" would be "If Not FileID = Nothing Then".
