Add event receiver to a SharePoint list

Recently I have created a generic function to add event receiver to specific SharePoint list.

Explaination is not need as code is very simple to understand.

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;

            }

        }

    }
