Syntax
C#
Parameters
- path
- The relative or absolute path to the directory to search. This string is not case-sensitive.
- searchPattern
- The search string to match against the names of files in path. This parameter can contain a combination of valid literal path and wildcard (* and ?) characters, but doesn't support regular expressions.
Return Value
An array of the full-path file names in the specified directory that match the specified search pattern or an empty array if no files found.Exceptions
| Exception | Description |
|---|---|
| System.IO.IOException | path is a file name. -or- A network error has occurred. |
| System.UnauthorizedAccessException | The caller does not have the required permission. |
| System.ArgumentException | path is a zero-length string, contains only white space, or contains one or more invalid characters. -or- searchPattern does not contain a valid pattern. |
| System.ArgumentNullException | path or searchPattern
is null. |
| System.IO.DirectoryNotFoundException | The specified path is not found or invalid (for example, it is on an unmapped drive). |
Remarks
The following wildcard specifiers are permitted in searchPattern. * (asterisk) - 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 searchPattern string "*t" searches for all names in path ending with the letter "t". The searchPattern string "s*" searches for all names in path beginning with the letter "s". searchPattern cannot end in two periods ("..") or contain two periods ("..") followed by '/' or '\', nor can it contain any invalid characters.
