Public Overrides ReadOnly Property CanSeek As Boolean
Property Value
This property always returns false
.
Examples
The following code example demonstrates displaying the value of this property.
static void DisplayStreamProperties( NegotiateStream^ stream )
{
Console::WriteLine( L"Can read: {0}", stream->CanRead );
Console::WriteLine( L"Can write: {0}", stream->CanWrite );
Console::WriteLine( L"Can seek: {0}", stream->CanSeek );
try
{
// If the underlying stream supports it, display the length.
Console::WriteLine( L"Length: {0}", stream->Length );
}
catch ( NotSupportedException^ )
{
Console::WriteLine( L"Cannot get the length of the underlying stream." );
}
if ( stream->CanTimeout )
{
Console::WriteLine( L"Read time-out: {0}", stream->ReadTimeout );
Console::WriteLine( L"Write time-out: {0}", stream->WriteTimeout );
}
}
static void DisplayStreamProperties(NegotiateStream stream)
{
Console.WriteLine("Can read: {0}", stream.CanRead);
Console.WriteLine("Can write: {0}", stream.CanWrite);
Console.WriteLine("Can seek: {0}", stream.CanSeek);
try
{
// If the underlying stream supports it, display the length.
Console.WriteLine("Length: {0}", stream.Length);
} catch (NotSupportedException)
{
Console.WriteLine("Cannot get the length of the underlying stream.");
}
if (stream.CanTimeout)
{
Console.WriteLine("Read time-out: {0}", stream.ReadTimeout);
Console.WriteLine("Write time-out: {0}", stream.WriteTimeout);
}
}
Remarks
You should not attempt to set the position of the NegotiateStream object or its underlying stream. The underlying stream is specified when you create an instance of the NegotiateStream class.
