(Mono C#) OneDrive -- List Root DirectorySee more OneDrive ExamplesThis gets the collection of DriveItem children of the root DriveItem. In OneDrive, a driveItem resource represents a file, folder, or other item stored in a drive. All file system objects in OneDriveare returned as driveItem resources (which are JSON objects). This example returns the collection of child DriveItems for the root DriveItem. Note: This example requires Chilkat v9.5.0.97 or greater. For more information, see https://learn.microsoft.com/en-us/onedrive/developer/rest-api/api/driveitem_list_children?view=odsp-graph-online
