![]() ![]() Therefore, when you are working with many files and directories, EnumerateFiles can be more efficient. 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. For example, using a search pattern of "*1*.txt" returns "longfilename.txt" because the equivalent 8.3 file name format is "LONGFI~1.TXT". You can query for invalid characters by using the GetInvalidPathChars method.īecause this method checks against file names with both the 8.3 file name format and the long file name format, a search pattern similar to "*1*.txt" may return unexpected file names. SearchPattern cannot end in two periods (".") or contain two periods (".") followed by DirectorySeparatorChar or AltDirectorySeparatorChar, nor can it contain any invalid characters. The searchPattern string "s*" searches for all names in path beginning with the letter "s". For example, the searchPattern string "*t" searches for all names in path ending with the letter "t". Zero or more characters in that position.Ĭharacters other than the wildcard are literal characters. The following wildcard specifiers are permitted in searchPattern. SearchPattern can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The returned file names are appended to the supplied path parameter and the order of the returned file names is not guaranteed use the Sort method if a specific sort order is required. Insert logic for processing found files here.Ĭonsole::WriteLine( "Processed file '", e.ToString()) ![]() For Directory::GetFiles and Directory::GetDirectories The example is configured to catch all errors common to this method. The following example demonstrates how to use the GetFiles method to return file names from a user-specified location. The specified path is not found or is invalid (for example, it is on an unmapped drive).
