SslStream.ReadTimeout Property
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets or sets the amount of time, expressed in milliseconds, a read operation blocks waiting for data.
public:
virtual property int ReadTimeout { int get(); void set(int value); };
public override int ReadTimeout { get; set; }
member this.ReadTimeout : int with get, set
Public Overrides Property ReadTimeout As Integer
Property Value
The amount of time, in milliseconds, that elapses before a synchronous read operation fails.
Examples
The following code example demonstrates setting the value of this property.
static void ProcessClient( TcpClient^ client )
{
// A client has connected. Create the
// SslStream using the client's network stream.
SslStream^ sslStream = gcnew SslStream( client->GetStream(),false );
// Authenticate the server but don't require the client to authenticate.
try
{
sslStream->AuthenticateAsServer( serverCertificate, false, true );
// false == no client cert required; true == check cert revocation.
// Display the properties and settings for the authenticated stream.
DisplaySecurityLevel( sslStream );
DisplaySecurityServices( sslStream );
DisplayCertificateInformation( sslStream );
DisplayStreamProperties( sslStream );
// Set timeouts for the read and write to 5 seconds.
sslStream->ReadTimeout = 5000;
sslStream->WriteTimeout = 5000;
// Read a message from the client.
Console::WriteLine( L"Waiting for client message..." );
String^ messageData = ReadMessage( sslStream );
Console::WriteLine( L"Received: {0}", messageData );
// Write a message to the client.
array<Byte>^message = Encoding::UTF8->GetBytes( L"Hello from the server.<EOF>" );
Console::WriteLine( L"Sending hello message." );
sslStream->Write( message );
}
catch ( AuthenticationException^ e )
{
Console::WriteLine( L"Exception: {0}", e->Message );
if ( e->InnerException != nullptr )
{
Console::WriteLine( L"Inner exception: {0}", e->InnerException->Message );
}
Console::WriteLine( L"Authentication failed - closing the connection." );
sslStream->Close();
client->Close();
return;
}
finally
{
// The client stream will be closed with the sslStream
// because we specified this behavior when creating
// the sslStream.
sslStream->Close();
client->Close();
}
}
static void ProcessClient (TcpClient client)
{
// A client has connected. Create the
// SslStream using the client's network stream.
SslStream sslStream = new SslStream(
client.GetStream(), false);
// Authenticate the server but don't require the client to authenticate.
try
{

// Display the properties and settings for the authenticated stream.

}

// because we specified this behavior when creating
// the sslStream.

Remarks
This property returns the value returned by invoking ReadTimeout on the underlying stream. When you set this property, the ReadTimeout value on the underlying stream is set to the specified value.
If the underlying stream is a NetworkStream, ReadTimeout is in milliseconds and is set to Infinite by default so that read operations do not timeout.
