Sometimes it is necessary to process a sequential text file multiple times from the beginning during a program's execution. After the file is processed the first time, the file pointer is at the end of the file. How can you reread the file at this point?

What will be an ideal response?

After the file is processed the first time, the file pointer is at the end of the file and no more records can be read. To reread the file, you could close it and reopen it, but that requires unnecessary overhead. Instead, you can just reposition the file pointer using the Seek() method and the SeekOrigin enumeration.
