Examples

The following code example iterates through the collection of alerts for a specified user and uses the indexer to display the title of each list item and the title of its list.

The example assumes the existence of a .aspx page that contains a label control.

Dim site As SPSite = SPControl.GetContextSite(Context)
Dim web As SPWeb = site.AllWebs("Site_Name")
Dim alerts As SPAlertCollection = web.Users("User_Loggin_Name").Alerts
Dim i As Integer

For i = 0 To alerts.Count - 1
    Label1.Text += SPEncode.HtmlEncode(alerts(i).Title) + "<BR>"
Next i
SPSite oSiteCollection = SPContext.Current.Site;
SPWeb oWebsite = oSiteCollection.AllWebs["Site_Name"];
SPAlertCollection collAlerts = oWebsite.Users["Username"].Alerts;
for (int intIndex=0; intIndex<collAlerts.Count; intIndex++)
{
    Label1.Text += SPEncode.HtmlEncode(collAlerts[intIndex].Title) + "<BR>";
}
oWebsite.Dispose();

Note

Certain objects implement the IDisposable interface, and you must avoid retaining these objects in memory after they are no longer needed. For information about good coding practices, see Disposing Objects.
