CopyDirectory(String, String)
Copies a directory to another directory.
public:
void CopyDirectory(System::String ^ sourceDirectoryName, System::String ^ destinationDirectoryName);public void CopyDirectory (string sourceDirectoryName, string destinationDirectoryName);member this.CopyDirectory : string * string -> unitPublic Sub CopyDirectory (sourceDirectoryName As String, destinationDirectoryName As String)Parameters
- sourceDirectoryName
- String
The directory to be copied.
- destinationDirectoryName
- String
The location to which the directory should be copied.
Exceptions
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 \\.\).
destinationDirectoryName or sourceDirectoryName is Nothing or an empty string.
The source directory does not exist.
The source path and target path are the same.
The operation is cyclic.
The path exceeds the system-defined maximum length.
A folder name in the path contains a colon (:) or is in an invalid format.
The user lacks necessary permissions to view the path.
A destination file exists but cannot be accessed.
Examples
The following example copies the directory TestDirectory1 into TestDirectory2, overwriting existing files.
My.Computer.FileSystem.CopyDirectory("C:\TestDirectory1", "C:\TestDirectory2", True)
Replace C:\TestDirectory1 and C:\TestDirectory2 with the path and name of the directory you wish to copy and the location to which you wish to copy it.
Remarks
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.
