Syntax

C++

public abstract class TcpConnectionInformation

Constructors

	Name	Description
	TcpConnectionInformation()	Initializes a new instance of the TcpConnectionInformation class.

Properties

	Name	Description
	LocalEndPoint	Gets the local endpoint of a Transmission Control Protocol (TCP) connection.
	RemoteEndPoint	Gets the remote endpoint of a Transmission Control Protocol (TCP) connection.
	State	Gets the state of this Transmission Control Protocol (TCP) connection.

Methods

	Name	Description
	Equals(Object)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Remarks

TCP is a connection-oriented reliable protocol for transporting data between networked computers. It is defined in IETF RFC 793.

Examples

The following example displays endpoint information for active TCP connections.

C++

        public static void GetTcpConnections()
        {
            IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
//            TcpConnectionInformation connections = properties.GetActiveTcpConnections();
            TcpConnectionInformation[] connections = properties.GetActiveTcpConnections();

            foreach (TcpConnectionInformation t in connections)
            {
                Console.Write("Local endpoint: {0} ",t.LocalEndPoint.Address);
                Console.Write("Remote endpoint: {0} ",t.RemoteEndPoint.Address);
                Console.WriteLine("{0}",t.State);
            }
            Console.WriteLine();
        }
