SocketAddress Class

Stores serialized information from EndPoint derived classes.

Namespace: System.Net
Assembly: System (in system.dll)

public class SocketAddress
public class SocketAddress
public class SocketAddress
Not applicable.

The first 2 bytes of the underlying buffer are reserved for the AddressFamily enumerated value. When the SocketAddress is used to store a serialized IPEndPoint, the third and fourth bytes are used to store port number information. The next bytes are used to store the IP address. You can access any information within this underlying byte buffer by referring to its index position; the byte buffer uses zero-based indexing. You can also use the Family and Size properties to get the AddressFamily value and the buffer size, respectively. To view any of this information as a string, use the ToString method.

The following example demonstrates how to use SocketAddress to serialize an instance of the EndPoint class. After serialization, the underlying byte buffer of the SocketAddress contains all of the IPEndPoint state information.


//Creates an IpEndPoint.
IPAddress ipAddress = Dns.Resolve("www.contoso.com").AddressList[0];
IPEndPoint ipLocalEndPoint = new IPEndPoint(ipAddress, 11000);

//Serializes the IPEndPoint. 
SocketAddress socketAddress = ipLocalEndPoint.Serialize();

//Verifies that ipLocalEndPoint is now serialized by printing its contents.
Console.WriteLine("Contents of the socketAddress are: " + socketAddress.ToString());
//Checks the Family property.
Console.WriteLine("The address family of the socketAddress is: " + socketAddress.Family.ToString());
//Checks the underlying buffer size.
Console.WriteLine("The size of the underlying buffer is: " + socketAddress.Size.ToString());


//Creates an IpEndPoint.
IPAddress ipAddress = (IPAddress)Dns.Resolve(
    "www.contoso.com").get_AddressList().get_Item(0);
IPEndPoint ipLocalEndPoint = new IPEndPoint(ipAddress, 11000);

//Serializes the IPEndPoint. 
SocketAddress socketAddress = ipLocalEndPoint.Serialize();

//Verifies that ipLocalEndPoint is now serialized by printing its 
//contents.
Console.WriteLine(("Contents of the socketAddress are: "
    + socketAddress.ToString()));

//Checks the Family property.
Console.WriteLine(("The address family of the socketAddress is: " 
    + socketAddress.get_Family()));

//Checks the underlying buffer size.
Console.WriteLine(("The size of the underlying buffer is: " 
    + socketAddress.get_Size()));
