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/api/guides/file-locking


Can someone Help me ?

What I have tried:

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
