Namespace:   Microsoft.VisualBasic.MyServices

public void CopyDirectory(
	string sourceDirectoryName,
	string destinationDirectoryName
)

Parameters

sourceDirectoryName
Type: System.String

The directory to be copied.

destinationDirectoryName
Type: System.String

The location to which the directory should be copied.

Exception Condition
ArgumentException

The new name specified for the directory contains a colon (:) or slash (\ or /).

ArgumentException

The path is not valid for one of the following reasons: it is a zero-length string; it contains only white space; it contains invalid characters; or it is a device path (starts with \\.\).

ArgumentNullException

destinationDirectoryName or sourceDirectoryName is Nothing or an empty string.

DirectoryNotFoundException

The source directory does not exist.

IOException

The source directory is a root directory

IOException

The combined path points to an existing file.

IOException

The source path and target path are the same.

InvalidOperationException

The operation is cyclic.

PathTooLongException

The path exceeds the system-defined maximum length.

NotSupportedException

A folder name in the path contains a colon (:) or is in an invalid format.

SecurityException

The user lacks necessary permissions to view the path.

UnauthorizedAccessException

A destination file exists but cannot be accessed.

This method copies the contents of the directory as well as the directory itself. If the target directory does not exist, it is created. If a directory with the same name exists in the target location, the contents of the two directories are merged. You can specify a new name for the directory during the operation.

When copying files within a directory, exceptions may be thrown that are caused by a specific file. When such exceptions are thrown, they are consolidated into a single exception whose Data property holds entries in the form of an IDictionary in which the file or directory path is the key and the specific exception message is contained in the corresponding value. Use For…Each to enumerate through the entries.
