Parameters
Permissions
Type Reason System.Security.Permissions.FileIOPermission Requires permission to read from sourceDirName, and write to sourceDirName and destDirName. See System.Security.Permissions.FileIOPermissionAccess.Read, System.Security.Permissions.FileIOPermissionAccess.Write.
Exceptions
Type Reason ArgumentException sourceDirName or destDirName is a zero-length string, contains only white space, or contains implementation-specific invalid characters. ArgumentNullException sourceDirName or destDirName is null. System.Security.SecurityException The caller does not have the required permission. System.IO.IOException An attempt was made to move a directory to a different volume,
-or-
destDirName already exists.
-or-
sourceDirName and destDirName refer to the same file or directory.
System.IO.DirectoryNotFoundException sourceDirName was not found. System.IO.PathTooLongException The length or absolute path information for sourceDirName or destDirName exceeds the system-defined maximum length. UnauthorizedAccessException The caller does not have the required permission.
Remarks
The destDirName argument cannot specify a location on a different disk or volume than sourceDirName. The sourceDirName and destDirName arguments cannot identify the same file or directory.
Note: This method throws a System.IO.IOException if, for example, you try to move "\mydir" to "\public", and "\public" already exists. You must specify "\public\mydir" as the destDirName.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.
Note: To obtain the current working directory, see Directory.GetCurrentDirectory.
