	SearchOption searchOption
)

Parameters

path
Type: SystemString
The directory to search.
searchPattern
Type: SystemString
The search string to match against the names of directories in path. This parameter can contain a combination of valid literal path and wildcard (WildcardStarMatchAll and WildcardQuestion) characters, but does not support regular expressions.
searchOption

Exceptions
Remarks

The EnumerateFileSystemEntries and GetFileSystemEntries methods differ as follows: When you use EnumerateFileSystemEntries, you can start enumerating the collection of entries before the whole collection is returned; when you use GetFileSystemEntries, you must wait for the whole array of entries to be returned before you can access the array. Therefore, when you are working with many files and directories, EnumerateFiles can be more efficient.
