示例1: GetChildDirectories
/// <summary>
/// Returns all child directories of the given directory.
/// </summary>
/// <remarks>
/// This will return all native child directories of the given directory together with all virtual child
/// directories. The native child directories are taken directly from the given <paramref name="directoryAccessor"/>,
/// the virtual child directories are obtained by taking the root directories of each chained resource provider applied
/// to the child files of the given directory.
/// If, for example, the given <paramref name="directoryAccessor"/> contains a child directory "A" and a child
/// archive file "B" which can work as input for an installed archive provider, providing the root directory "C"
/// of that archive, this method will return the resource accessors for directories "A" and "C".
/// </remarks>
/// <param name="directoryAccessor">Directory resource accessor to get all child directories for.</param>
/// <param name="showSystemResources">If set to <c>true</c>, system resources like the virtual drives and directories of the
/// <see cref="IResourceMountingService"/> will also be returned, else removed from the result value.</param>
/// <returns>Collection of directory accessors for all native and virtual child directories or <c>null</c>,
/// if the given <paramref name="directoryAccessor"/> does not point to a directory and
/// if there is no chained resource provider to unfold the given file.</returns>
