A Program That Reads from a Sequential Access Data File

Question

Examlex · Accepted Answer

The Answer is A program that reads from a sequential access data file contains many similar components to one that writes to a file.For example, a FileStream object is created, as in a program that writes to a file.However, the access must be FileAccess.Read (or ReadWrite), as in the following statement:
FileStream inFile =
new FileStream(FILENAME, FileMode.Open, FileAccess.Read);
Then, as when data is being written, the FileStream object is passed to a StreamReader object's constructor, as in the following statement:
StreamReader reader = new StreamReader(inFile);
After the StreamReader has been defined, the ReadLine() method can be used to retrieve one line at a time from the data file.For example, the following statement gets one line of data from the file and stores it in a string named recordIn:
string recordIn = reader.ReadLine();
