text files

Back 4

another name for sequential file

Front 5

Back 5

programmers refer sequence of characters to

Front 6

stream writer object

Back 6

used to write a stream of characters to a sequential access file

Front 7

create text method

-when a file is open for output, the computer creates a new, empty file to which data can be written

-if the file already exists, the computer erases content of the file before writing any data to it

Front 8

appendtext method

Back 8

used with a StreamWriter variable to open a sequential access file for append

Front 9

write method

Back 9

used with a StreamWriter variable to write data to a sequential access file; differs from the WriteLine method in that it does not write a newline character after the data

Front 10

writeline method

Back 10

used with a StreamWriter variable to write data to a sequential access file; differs from the Write method in that it writes a newline character after the data

Front 11

close method

Back 11

closes an output sequential access file

Front 12

open text method

Back 12

used after declaring a stream reader variable, its used to open a sequential file for input, which automatically creates a stream Reader object

-if computer finds the file, it opens the file for input

-if computer does not find the file, a run time error occurs

Front 13

exists method
