);

Parameters

path
The path to which the current working directory is set.

Exceptions

Exception Type Condition
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.

Remarks

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.
