Return Value
Type: System. . :: . .Int32
An integer representing the next character to be read, or -1 if there are no characters to be read or if the stream does not support seeking.
Remarks
The Peek method returns an integer value in order to determine whether the end of the file, or another error has occurred. This allows a user to first check if the returned value is -1 before casting it to a Char type.
The current position of the StreamReader object is not changed by Peek.
