Reader. Peek Method
Returns the next available character but does not consume it.
public: override int Peek();
public override int Peek ();
override this.Peek : unit -> int
Public Overrides Function Peek () As Integer
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 current reader is closed.
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.
This method overrides the TextReader.Peek method.
The current position of the
StringReader is not changed by this operation.
