A value from the DTSFileSystemOperation enumeration indicating the type of operation to perform.

示例

The following code example creates a FileSystemTask as an Executable in a package. The FileSystemTask copies a test folder, which contains two subfolders and a .txt file, to another folder. The operation to perform is a copy of the directory and its child folders and files, so Operation is set to CopyDirectory.
