The following code example shows how to use the PollTime property.

// Get the current PollTime property value.
Int32 pollTimeValue = sqlCdd.PollTime;

// Set the PollTime property to 1000 milliseconds.
sqlCdd.PollTime = 1000;

' Get the current PollTime property value.
Dim pollTimeValue As Int32 = sqlCdd.PollTime

' Set the PollTime property to 1000 milliseconds.
sqlCdd.PollTime = 1000

Remarks

The PollTime property allows you to programmatically access and modify the pollTime attribute of an add element of the databases node in a configuration file.

After you configure the relationship between an item stored in an ASP.NET application's cache and a specific SQL Server database table, an instance of the SqlCacheDependency class monitors the table so that when an item in the table changes, the item is automatically updated in or removed from the cache. The monitoring happens at the frequency specified by the PollTime.
