c# - Why is the Destructor not being called? -

i have interesting scenario class inform entity has been destroyed; however, not doing want too.

the problem

the deconstructor, reason not supposed do.

the question

why destructor not being invoked , make sure necessary clean up.

the code

so here have informer ~

class connection  {    public const int port = 50000;// can range between 49152 , 65536      //teh constructor     public boolean connect()     {         //setinformation         information.id = 545;          using (var webserv = new clientsdksoapclient("clientsdksoap"))         {             continueconnection.waitone();             webserv.clientlogin(information);         }         return true;     }      ~connection()     {         using (var webserv = new clientsdksoapclient("clientsdksoap"))         {             webserv.clientlogout(information);         }     } } 

additional information

i want web service record if connection class destroyed given reason. when client connecting, works perfectly. web service records every method called it. if call clientlogout explicitly, work.

i aware can implement idisposable; however, object not intended used within lifetime of 1 method. in fact, intended use entire duration of program , failure of object results in failure of entire project. (although suppose main method...)

i need release network connection; however, not in program, in program , unless clientlogout called, won't released.

my research

microsoft says should use deconstructor release of unmanaged resources making explicit reference network connections. ones got quite stumped.

i think should implement dispose pattern connection class, rather relying on obscure deconstructor metaphor. "canonical" way it.

public class connection : idisposable  // <== inherit idisposable interface {     public const int port = 50000;// can range between 49152 , 65536      private sometype webserv; // use whatever real type appropriate here.     private information information = new information();  // or whatever      // real constructor.     public connection()     {         //setinformation         information.id = 545;          webserv = new clientsdksoapclient("clientsdksoap"))         webserv.continueconnection.waitone();         webserv.clientlogin(information);     }      // implement idisposable interface     public void dispose()     {         webserv.clientlogout(information);     } } 

and use thusly

using (var connection = new connection()) {     // use connection here. } 

the client logged out when leave using block.
