c# - How to check message arrival in service bus at every 20 seconds? -

i using service bus of azure hold list of messages means messages can enter in service bus @ time.

so want keep watch on service bus check whether message there in service or not.it want keep watch on service bus regarding message arrival in service bus @ interval 0f 20 seconds.

in every 20 seconds check message arrival in service bus , want perform in background asynchronously.

i want call below method in every 20 seconds in background:

 private static void receivemessages()         {             // peeklock mode (default) applications require "at least once" delivery of messages              subscriptionclient agentsubscriptionclient = subscriptionclient.create(topicname, "agentsubscription");             brokeredmessage message = null;             while (true)             {                 try                 {                     //receive messages agent subscription                     message = agentsubscriptionclient.receive(timespan.fromseconds(5));                     if (message != null)                     {                         console.writeline("\nreceiving message agentsubscription...");                         console.writeline(string.format("message received: id = {0}, body = {1}", message.messageid, message.getbody<string>()));                         // further custom message processing go here...                         message.complete();                     }                     else                     {                         //no more messages in subscription                         break;                     }                 }                 catch (messagingexception e)                 {                     if (!e.istransient)                     {                         console.writeline(e.message);                         throw;                     }                     else                     {                         handletransienterrors(e);                     }                 }             }              // receiveanddelete mode, applications require "best effort" delivery of messages             subscriptionclient auditsubscriptionclient = subscriptionclient.create(topicname, "auditsubscription", receivemode.receiveanddelete);             while (true)             {                 try                 {                     message = auditsubscriptionclient.receive(timespan.fromseconds(5));                     if (message != null)                     {                         console.writeline("\nreceiving message auditsubscription...");                         console.writeline(string.format("message received: id = {0}, body = {1}", message.messageid, message.getbody<string>()));                         // further custom message processing go here...                     }                     else                     {                         console.writeline("\nno more messages in subscription");                         //no more messages in subscription                         break;                     }                  }                 catch (messagingexception e)                 {                     if (!e.istransient)                     {                         console.writeline(e.message);                         throw;                     }                 }             }              agentsubscriptionclient.close();             auditsubscriptionclient.close();         } 

so can tell me how call above method every 20 seconds?

the beginner-friendly solution is:

drag timer toolbox, give name, set desired interval , set "enabled" true. double click timer , visual studio (or whatever using) write following code:

private void wait_tick(object sender, eventargs e) {     refreshtext(); //add method want call here. } 

or this

private timer timer1;  public void inittimer() {     timer1 = new timer();     timer1.tick += new eventhandler(timer1_tick);     timer1.interval = 2000; // in miliseconds     timer1.start(); }  private void timer1_tick(object sender, eventargs e) {     isonline() }
