DirectoryInfo.GetDirectories Method (String)

Returns an array of directories in the current DirectoryInfo matching the given search criteria.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public DirectoryInfo[] GetDirectories(
	string searchPattern
)

Parameters

searchPattern
Type: System.String
The search string. For example, "System*" can be used to search for all directories that begin with the word "System".

Return Value

Type: System.IO.DirectoryInfo[]
An array of type DirectoryInfo matching searchPattern.

ExceptionCondition
ArgumentException

searchPattern contains one or more invalid characters defined by the GetInvalidPathChars method.

ArgumentNullException

searchPattern is null.

DirectoryNotFoundException

The path encapsulated in the DirectoryInfo object is invalid (for example, it is on an unmapped drive).

UnauthorizedAccessException

The caller does not have the required permission.

Wildcards are permitted. For example, the searchPattern string "*t" searches for all directory names in path ending with the letter "t". The searchPattern string "s*" searches for all directory names in path beginning with the letter "s".

The string ".." can only be used in searchPattern if it is specified as a part of a valid directory name, such as in the directory name "a..b". It cannot be used to move up the directory hierarchy.

If there are no subdirectories, or no subdirectories match the searchPattern parameter, this method returns an empty array.

This method pre-populates the values of the following DirectoryInfo properties:

The following example counts the directories in a path that contain the specified letter.


using System;
using System.IO;

class Test 
{
    public static void Main() 
    {
        try 
        {
            DirectoryInfo di = new DirectoryInfo(@"c:\");

            // Get only subdirectories that contain the letter "p."
            DirectoryInfo[] dirs = di.GetDirectories("*p*");
            Console.WriteLine("The number of directories containing the letter p is {0}.", dirs.Length);

            foreach (DirectoryInfo diNext in dirs) 
            {
                Console.WriteLine("The number of files in {0} is {1}", diNext, 
                    diNext.GetFiles().Length);
            }
        } 
        catch (Exception e) 
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }
    }
}
