DirectoryInfo.EnumerateDirectories Method (String)
Returns an enumerable collection of directory information that matches a specified search pattern.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.String
The search string. The default pattern is "*", which returns all directories.
The following wildcard specifiers are permitted in the searchPattern parameter.
Zero or more characters.
Exactly one character.
The EnumerateDirectories and GetDirectories methods differ as follows: When you use EnumerateDirectories, you can start enumerating the collection of DirectoryInfo objects before the whole collection is returned; when you use GetDirectories, you must wait for the whole array of DirectoryInfo objects to be returned before you can access the array. Therefore, when you are working with many files and directories, EnumerateDirectories can be more efficient.
This method pre-populates the values of the following DirectoryInfo properties:
The returned collection is not cached; each call to the GetEnumerator method on the collection will start a new enumeration.
