member GetDirectories : searchPattern:string * searchOption:SearchOption -> DirectoryInfo
The search string to match against the names of directories. This parameter can contain a combination of valid literal path and wildcard (* and ?) characters (see Remarks), but doesn't support regular expressions. The default pattern is "*", which returns all files.
One of the enumeration values that specifies whether the search operation should include only the current directory or all subdirectories.
Return ValueType: System.IO.DirectoryInfo
An array of type DirectoryInfo matching searchPattern.
searchPattern contains one or more invalid characters defined by the GetInvalidPathChars method.
searchPattern is null.
searchOption is not a valid SearchOption value.
The path encapsulated in the DirectoryInfo object is invalid (for example, it is on an unmapped drive).
The caller does not have the required permission.
searchPattern can be a combination of literal and wildcard characters, but doesn't support regular expressions. The following wildcard specifiers are permitted in searchPattern.
Zero or more characters in that position.
? (question mark)
Zero or one character in that position.
Characters other than the wildcard are literal characters. For example, the string "*t" searches for all names in ending with the letter "t". ". The searchPattern string "s*" searches for all names in path beginning with the letter "s".
If there are no subdirectories, or no subdirectories match the searchPattern parameter, this method returns an empty array.
