Add event receiver to a SharePoint list

This is very generic and everyone knows how to add an event receiver. But, usually we attach the event receiver on a list template, site etc. This post deals with adding event receiver to a specific list.

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

This is very straight forward code and hope you got it.
