CSharpTest.Net.Library Assembly > CSharpTest.Net.IO Namespace > ClampedStream Class > ClampedStream Constructor : ClampedStream Constructor(Stream,Int64,Int64)

Visual Basic (Declaration)
C#

rawStream: The stream to use for read/write

start: The position in the stream that should start the range of allowed bytes

length: The maximum length that can be read from the stream

Creates a stream that limits the users ability to modify data to the specified range

Syntax

Visual Basic (Declaration)
Public Function New( _ ByVal rawStream As Stream, _ ByVal start As Long, _ ByVal length As Long _ )

C#
public ClampedStream( Stream rawStream, long start, long length )

Parameters

rawStream: The stream to use for read/write
start: The position in the stream that should start the range of allowed bytes
length: The maximum length that can be read from the stream
