DirectoryInfo.MoveTo Method
Assembly: mscorlib (in mscorlib.dll)
| Exception type | Condition |
|---|---|
| destDirName is a null reference (Nothing in Visual Basic). -or- The directory being moved and the destination directory have the same name. |
|
| destDirName is an empty string (''"). |
|
| An attempt was made to move a directory to a different volume, or destDirName already exists. |
|
| The caller does not have the required permission. |
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, or specify a new directory name such as "c:\\newdir".
This method permits moving a directory to a read-only directory. The read/write attribute of neither directory is affected.

The following example demonstrates moving a directory.
using System; using System.IO; public class MoveToTest { public static void Main() { // Make a reference to a directory. DirectoryInfo di = new DirectoryInfo("TempDir"); // Create the directory only if it does not already exist. if (di.Exists == false) di.Create(); // Create a subdirectory in the directory just created. DirectoryInfo dis = di.CreateSubdirectory("SubDir"); // Move the main directory. Note that the contents move with the directory. if (Directory.Exists("NewTempDir") == false) di.MoveTo("NewTempDir"); try { // Attempt to delete the subdirectory. Note that because it has been // moved, an exception is thrown. dis.Delete(true); } catch (Exception) { // Handle this exception in some way, such as with the following code: // Console.WriteLine("That directory does not exist."); } // Point the DirectoryInfo reference to the new directory. //di = new DirectoryInfo("NewTempDir"); // Delete the directory. //di.Delete(true); } }
