GetDirectories Method (String, SearchOption)

DirectoryInfo.GetDirectories Method (String, SearchOption)

Returns an array of directories in the current DirectoryInfo matching the given search criteria and using a value to determine whether to search subdirectories.

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

public DirectoryInfo[] GetDirectories (
	string searchPattern,
	SearchOption searchOption
public DirectoryInfo[] GetDirectories (
	String searchPattern, 
	SearchOption searchOption
public function GetDirectories (
	searchPattern : String, 
	searchOption : SearchOption
) : DirectoryInfo[]
Not applicable.



The search string, such as "System*", used to search for all directories beginning with the word "System".


One of the values of the SearchOption enumeration that specifies whether the search operation should include only the current directory or should include all subdirectories.

Return Value

An array of type DirectoryInfo matching searchPattern.

Exception typeCondition


searchPattern is a null reference (Nothing in Visual Basic).


The path encapsulated in the DirectoryInfo object is invalid, such as being on an unmapped drive.


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.

The following example lists all of the directories and files that begin with the letter "c" in "c:\".

using System;
using System.IO;

class App
    public static void Main()
        // Specify the directory you want to manipulate.
        string path = @"c:\";
        string searchPattern = "c*";

        DirectoryInfo di = new DirectoryInfo(path);
        DirectoryInfo[] directories = 
            di.GetDirectories(searchPattern, SearchOption.TopDirectoryOnly);

        FileInfo[] files = 
            di.GetFiles(searchPattern, SearchOption.TopDirectoryOnly);

            "Directories that begin with the letter \"c\" in {0}", path);
        foreach (DirectoryInfo dir in directories)
                "{0,-25} {1,25}", dir.FullName, dir.LastWriteTime);

            "Files that begin with the letter \"c\" in {0}", path);
        foreach (FileInfo file in files)
                "{0,-25} {1,25}", file.Name, file.LastWriteTime);
    } // Main()
} // App()
