Examples

The following code example iterates through all the alerts on a site for a specified user, generates an array to store the GUID of each alert, and then uses each GUID to display the frequency and event type for each alert.

Dim site As SPSite = SPControl.GetContextSite(Context)
Dim web As SPWeb = site.AllWebs("Site_Name")
Dim alerts As SPAlertCollection = web.Users(TextBox1.Text).Alerts
Dim guids(alerts.Count) As System.Guid
Dim i As Integer

For i = 0 To alerts.Count - 1

    guids.SetValue(alerts(i).ID, i)

Next i

Dim j As Integer

For j = 0 To guids.Length - 1

    Label1.Text += alerts(guids(j)).AlertFrequency + "--" + 
        alerts(guids(j)).EventType + "<BR>"

Next j
SPSite oSite = SPContext.Current.Site;
SPWebCollection collWebsites = oSite.AllWebs;
foreach (SPWeb oWebsite in collWebsites)
{
    SPAlertCollection collAlerts = oWebsite.Alerts;

    foreach (SPAlert oAlert in collAlerts)
    {
        Label1.Text = SPEncode.HtmlEncode(oWebsite.Title) + " :: " +
            SPEncode.HtmlEncode(oAlert.Title) + " :: " +
        oAlert.User.LoginName + "<BR>";
    }
    oWebsite.Dispose();
}
