DirectoryInfo.GetDirectories Method (String, SearchOption)

public DirectoryInfo[] GetDirectories (
	string searchPattern,
	SearchOption searchOption
)

public DirectoryInfo[] GetDirectories (
	String searchPattern, 
	SearchOption searchOption
)

public function GetDirectories (
	searchPattern : String, 
	searchOption : SearchOption
) : DirectoryInfo[]

Parameters

searchPattern

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

searchOption

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

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 are found that match searchPattern, this method returns only the root directory.

The following table lists examples of other typical or related I/O tasks.

The following code 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);

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

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