Directory.GetFiles Method (String)
Returns the names of files (including their paths) in the specified directory.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.String
The relative or absolute path to the directory to search. This string is not case-sensitive.
Return ValueType: System.String
An array of the full names (including paths) for the files in the specified directory, or an empty array if no files are found.
path is a file name.
A network error has occurred.
The caller does not have the required permission.
path is a zero-length string, contains only white space, or contains one or more invalid characters. You can query for invalid characters by using the GetInvalidPathChars method.
path is a null reference (Nothing in Visual Basic).
The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters and file names must be less than 260 characters.
The specified path is not found or is invalid (for example, it is on an unmapped drive).
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.
The returned file names are appended to the supplied path parameter.
This method is identical to GetFiles(String, String) with the asterisk (*) specified as the search pattern.
The path parameter can specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see GetCurrentDirectory.
The order of the returned file names is not guaranteed; use the Sort() method if a specific sort order is required.
The path parameter is not case-sensitive.
