static member GetFiles :

        searchPattern : string * 
        searchOption : SearchOption -> string[] 

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

Type: System.IOSearchOption
One of the SearchOption enumeration values that specifies whether the searchOption should include only the current directory or should include all subdirectories.

Return Value

The returned file names are appended to the supplied path parameter.

The order of the returned file names is not guaranteed; use the Sort() method if a specific sort order is required.

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