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

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

disposeOfStream: True to dispose of the rawStream when this stream is disposed

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, _ ByVal disposeOfStream As Boolean _ )

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

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
disposeOfStream: True to dispose of the rawStream when this stream is disposed

Example

Library/Library.Test/TestClampedStream.cs

C#	Copy Code
MemoryStream ms = new MemoryStream(); BufferedStream bs = new BufferedStream(ms, 1024); using (Stream s = new ClampedStream(bs, 0, long.MaxValue, false)) { s.WriteByte(1); Assert.AreEqual(0, ms.Position); s.Flush(); Assert.AreEqual(1, ms.Position); ms.Position = 0; Assert.AreEqual(1, ms.ReadByte()); }

Copy Code

MemoryStream ms = new MemoryStream();
BufferedStream bs = new BufferedStream(ms, 1024);

using (Stream s = new ClampedStream(bs, 0, long.MaxValue, false))
{
    s.WriteByte(1);
    Assert.AreEqual(0, ms.Position);
    s.Flush();
    Assert.AreEqual(1, ms.Position);
    ms.Position = 0;
    Assert.AreEqual(1, ms.ReadByte());
}

VB.NET	Copy Code
Dim ms As New MemoryStream() Dim bs As New BufferedStream(ms, 1024) Using s As Stream = New ClampedStream(bs, 0, Long.MaxValue, False) s.WriteByte(1) Assert.AreEqual(0, ms.Position) s.Flush() Assert.AreEqual(1, ms.Position) ms.Position = 0 Assert.AreEqual(1, ms.ReadByte()) End Using

VB.NET

Copy Code

Dim ms As New MemoryStream()
Dim bs As New BufferedStream(ms, 1024)

Using s As Stream = New ClampedStream(bs, 0, Long.MaxValue, False)
    s.WriteByte(1)
    Assert.AreEqual(0, ms.Position)
    s.Flush()
    Assert.AreEqual(1, ms.Position)
    ms.Position = 0
    Assert.AreEqual(1, ms.ReadByte())
End Using
