Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Overrides Function Peek As Integer
public override int Peek()

Return Value

An integer representing the next character to be read, or -1 if no more characters are available or 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.

This method overrides the TextReader.Peek method.

The current position of the StringReader is not changed by this operation.
