You can specify relative or absolute path information in the path parameter. Relative path information is interpreted as relative to the current working directory, which you can determine by using the Directory.GetCurrentDirectory method. The returned directory names are prefixed with the value you provided in the path parameter. For example, if you provide a relative path in the path parameter, the returned directory names will contain a relative path.

The erload:System.IO.Directory.EnumerateDirectories and erload:System.IO.Directory.GetDirectories methods differ as follows: When you use erload:System.IO.Directory.EnumerateDirectories, you can start enumerating the collection of names before the whole collection is returned; when you use erload:System.IO.Directory.GetDirectories, you must wait for the whole array of names to be returned before you can access the array. Therefore, when you are working with many files and directories, erload:System.IO.Directory.EnumerateDirectories can be more efficient.

The returned collection is not cached; each call to the IEnumerable`1.GetEnumerator on the collection will start a new enumeration.
