Have you tried reading the MSDN for this?

The Read method blocks its return while you type input characters; it terminates when you press the Enter key. Pressing Enter appends a platform-dependent line termination sequence to your input (for example, Windows appends a carriage return-linefeed sequence). Subsequent calls to the Read method retrieve your input one character at a time. After the final character is retrieved, Read blocks its return again and the cycle repeats.
Note that you will not get a property value of -1 unless you perform one of the following actions: simultaneously press the Control modifier key and Z console key (CTRL+Z), which signals the end-of-file condition; press an equivalent key that signals the end-of-file condition, such as the F6 function key in Windows; or redirect the input stream to a source, such as a text file, that has an actual end-of-file character.
The ReadLine method, or the KeyAvailable property and ReadKey method are preferable to using the Read method.
