How to delete event receiver from a SharePoint list

In  Hot wo add event receiver to a SharePoint list, we saw how we added an event receiver to a list. Now, we will see how
to delete the existing event receiver on a list.

1. private void DeleteEventReceiverFromAList(string siteUrl)  


2.     {  


3.         using (SPSite site = new SPSite(siteUrl))  


4.         {  


5.             using(SPWeb web = site.OpenWeb())
    


6.             {  


7.                 try 


8.                 {  


9.                     SPList list = web.Lists["myList"];  


10.                     if (list != null)  


11.                     {  


12.                         string className = "EventReceiverClass";  


13.                         string asmName = "EventReceiverAssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=a865f0ecc234ea51";
     


14.                         web.AllowUnsafeUpdates = true;  


15.  


16.                         int receivers = list.EventReceivers.Count;
     


17.                         bool isAddedReceiverExist = false;  


18.                         bool isUpdatedReceiverExist = false;  


19.                         for (int i = 0; i < receivers; i++)
     


20.                         {  


21.                             SPEventReceiverDefinition eventReceiver = list.EventReceivers[i];
     


22.                             if (eventReceiver.Class == className && eventReceiver.Type == SPEventReceiverType.ItemAdded)
     


23.                             {  


24.                                 eventReceiver.Delete();  


25.                                 break;  


26.                             }  


27.                         }  


28.                     }  


29.                 }  


30.                 catch { }
     


31.                 finally 


32.                 {  


33.                     web.AllowUnsafeUpdates = false;  


34.                 }  


35.             }  


36.         }  


37.     } 

private void DeleteEventReceiverFromAList(string siteUrl)     {         using (SPSite site = new SPSite(siteUrl))         {             using(SPWeb web = site.OpenWeb())             {                 try                 {                     SPList list = web.Lists["myList"];                     if (list != null)                     {                         string className = "EventReceiverClass";                         string asmName = "EventReceiverAssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=a865f0ecc234ea51";                         web.AllowUnsafeUpdates = true;                          int receivers = list.EventReceivers.Count;                         bool isAddedReceiverExist = false;                         bool isUpdatedReceiverExist = false;                         for (int i = 0; i < receivers; i++)                         {                             SPEventReceiverDefinition eventReceiver = list.EventReceivers[i];                             if (eventReceiver.Class == className && eventReceiver.Type == SPEventReceiverType.ItemAdded)                             {                                 eventReceiver.Delete();                                 break;                             }                         }                     }                 }                 catch { }                 finally                 {                     web.AllowUnsafeUpdates = false;                 }             }         }     } 

In this code also, there is nothing to explain very detail. Please let me
