'Declaration Public Overridable Function Peek As Integer
public virtual int Peek()
An integer representing the next character to be read, or -1 if no more characters are available or the stream does not support seeking.
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 TextReader is not changed by this operation. The returned value is -1 if no more characters are available. The default implementation returns -1.
