Moves a file or a directory and its contents to a new location.
(in mscorlib.dll)
Visual Basic (Declaration)
Public Shared Sub Move ( _
sourceDirName As String, _
destDirName As String _
)
Dim sourceDirName As String
Dim destDirName As String
Directory.Move(sourceDirName, destDirName)
public static void Move(
string sourceDirName,
string destDirName
)
public:
static void Move(
String^ sourceDirName,
String^ destDirName
)
public static function Move(
sourceDirName : String,
destDirName : String
)
Parameters
- sourceDirName
- Type: System..::.String
The path of the file or directory to move.
- destDirName
- Type: System..::.String
The path to the new location for sourceDirName. If sourceDirName is a file, then destDirName must also be a file name.
| Exception | Condition |
|---|
| IOException | An attempt was made to move a directory to a different volume. -or-
destDirName already exists. -or- The sourceDirName and destDirName parameters refer to the same file or directory. |
| UnauthorizedAccessException | The caller does not have the required permission. |
| ArgumentException |
sourceDirName or destDirName is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars. |
| ArgumentNullException |
sourceDirName or destDirName is nullNothingnullptra 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. |
| DirectoryNotFoundException | The path specified by sourceDirName is invalid (for example, it is on an unmapped drive). |
This method throws an IOException if, for example, you try to move c:\mydir to c:\public, and c:\public already exists. You must specify "c:\\public\\mydir" as the destDirName parameter, provided that "mydir" does not exist under "c:\\public", or specify a new directory name such as "c:\\newdir".
The sourceDirName and destDirName arguments are 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.
For a list of common I/O tasks, see Common I/O Tasks.
The following example demonstrates how to move a directory and all files contained therein to a new location on the hard disk drive. The example is configured to catch all errors common to this method.
