"IPEndPoint"(C#)

[Eran]

Hi,

Can any one explain me how to use the "IPEndPoint" Class?
In the MSDN, I get the following results for "IPEndPoint":

"public IPAddress Address {get; set;}
Gets or sets the IP address of the endpoint

"
How do I get the IP of the endpoint using that method?

Are you trying to get the IP address from an existing endpoint? Can I see some existing code?

Put this line in the constructor.

ServerHostName = Dns.GetHostName ();

The following lines as global in the class

string ServerHostName ;
private string ServerIPAddr;

Put the following lines in the function you want.

IPHostEntry ipE = Dns.GetHostByName (ServerHostName); 
IPAddress [] addr = ipE.AddressList; 
for(int i= 0; i < addr.Length ; i++) 
{
    ServerIPAddr += addr[i].ToString(); 
}

This was one way to obtain IPADDRESS. I wanted to try the other method.

The IPEndPoint class represents a combination of an IP address and port. You use it to specify those when connecting to something. How is it you want to use it?

 

[Eran]

Well, according to Microsoft, the following method:
"public IPAddress Address {get; set;}"
gets or sets an IPaddress.

I just wanted to know how to set or get the IPaddress using this method.

 

[Divil]

Yes, but on what class is that property?

 

[Eran]

IPEndPoint class

I think youre misunderstanding here. That class doesnt provide a way to get or set the system ip address - its just how you specify what ip address to connect to when setting up a socket connection.

Oops...

I hope this might help you in understanding IPENDPoint.

IPENDPOINT Represents a network endpoint as an IP address and a port number it is used by SOCKET

[COLOR=green]// here you are get IP address of some server[/COLOR] 

IPAddress hostadd = Dns.Resolve(some server).AddressList[0];

[COLOR=green]// here you are initializing a new IPENDPOINT by telling it a complete target. 
//such as a server and its port[/COLOR]

IPEndPoint EPhost = new IPEndPoint(hostadd, 80);

[COLOR=green]// here you are definiing a new SOCKET which will use this end point to connect
// to target Host.[/COLOR]

Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
       ProtocolType.Tcp );
 
[COLOR=green]// Connects to the host using IPEndPoint.[/COLOR]
    s.Connect(EPhost);

I hope now you would have clear understanding about IPEndPoint.
