Methods

Copy(Directory, string, string, IOContext)

Copies the file src to Directoryto under the new file name dest.

If you want to copy the entire source directory to the destination one, you can do so like this: 
Directory to; // the directory to copy to
foreach (string file in dir.ListAll()) {
    dir.Copy(to, file, newFile, IOContext.DEFAULT); // newFile can be either file, or a new name
}

NOTE: this method does not check whether dest exist and will

overwrite it if it does.

Declaration
public override void Copy(Directory to, string src, string dest, IOContext context)
Parameters
Type Name Description
Directory to
string src
string dest
IOContext context

CreateSlicer(string, IOContext)

Creates an Directory.IndexInputSlicer for the given file name.

The underlying file handle is kept open until the Directory.IndexInputSlicer is closed.

Throws FileNotFoundException if the file does not exist.
