Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public static function SetCurrentDirectory(
	path : String
)

Parameters

path
Type: System.String

The path to which the current working directory is set.

ExceptionCondition
IOException

An IO error occurred.

ArgumentException

path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.

ArgumentNullException

path is a null reference (Nothing in Visual Basic).

PathTooLongException

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.

SecurityException

The caller does not have the required permission to access unmanaged code.

FileNotFoundException

The specified path was not found.

DirectoryNotFoundException

The specified directory was not found.

When the application terminates, the working directory is restored to its original location (the directory where the process was started).

The path parameter is permitted to 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 path parameter is not case-sensitive.

If you are setting the directory to a drive with removable media, for example to "A:" for a floppy disk or "E:" for a CD-ROM, you can determine whether the drive is ready with the IsReady property.
