Peek Method

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Returns the next available character but does not consume it.

Namespace:  System.IO
Assembly:  System.IO (in System.IO.dll)

public override int Peek()

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.

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.
