OneDrive -- List Root Directory
See more OneDrive Examples
This 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.
