Using SPAlert in SharePoint

In SharePoint Alerts are very important ,alert can be an email  message send to end user or it may be Short Message Service(SMS) from the SharePoint.In many situations it is required to configure alerts for the Lists/Libraries in SharePoint.

For example let us say you have a Quality Assurance SharePoint Site which has a document library related to documents about the process and other documents,and it is a mandatory to all the employees to follow the Quality process and even if there is any change or added new process,in this it is required for employee to alert if there is any modifications/added any new documents to this library.

Using SharePoint Model it is possible to know about the user's alerts using SPAlert class.

The Following code samples shows how to user's alert using SPAlert class.

SPSite mySiteCollection=null;
SPWeb mySPweb=null;
   Try
       {
//Get the SPSite by passing the url
mySiteCollection = new SPSite("http://QualityAssuranceSite /")
mySPweb = mySiteCollection.OpenWeb("Quality")
SPUserCollection  users = mySPweb .Users;
       //Iterate through each users in site
         foreach (SPUser user in users)
            {
              //Get alerts collections for the individual user
             SPAlertCollection alerts = user.Alerts;
         foreach (SPAlert alert in alerts)
            {
             
           // you can access the properties and methods from the alert object "alert"
//Title
string alertTitle=alert.Title;
//AlertFrequency
alert.AlertFrequency = Microsoft.SharePoint.SPAlertFrequency.Immediate;
       alert.Update();

            }
           }

}
Catch(SPExecption exception)
{
    Throw exception
}
Finally
{
    mySiteCollection.Dispose();
    mySPweb.Dispose();
}
