IDirectory.cs

namespace VS.Library.Interfaces
{
    using System.Collections.Generic;
    using System.IO;
    using System.Security.AccessControl;

    public interface IDirectory
    {
        bool Exists(string path);

        IEnumerable<string> GetFiles(string path, string searchPattern);

        DirectoryInfo CreateDirectory(string path);

        DirectoryInfo CreateDirectory(string path, DirectorySecurity directorySecurity);
    }
}
