Protected Sub SetUtcLastModified (utcLastModified As DateTime)

The time when the dependency last changed.
Examples
The following code example shows a class that inherits from the CacheDependency class. It creates a public method, ResetDependency
, that uses the SetUtcLastModified method to change the time at which the dependency was modified, and then calls the NotifyDependencyChanged method.
' Declare the class.
Public Class CustomCacheDependency
Inherits CacheDependency
' Constructor with no arguments
' provided by CacheDependency class.
Public Sub New()
End Sub
' Declare a Boolean field named disposedValue.
' This will be used by Disposed property.
Private disposedValue As Boolean
' Create accessors for the Disposed property.
Public Property Disposed As Boolean
Get
Return disposedValue
End Get
Set (ByVal value As Boolean)
disposedValue = value
End Set
End Property
' Create a public method that sets the latest
' changed time of the CustomCacheDependency
' and notifies the underlying CacheDependency that the
' dependency has changed, even though the HasChanged
' property is false.
Public Sub ResetDependency()
If Me.HasChanged = False
SetUtcLastModified(DateTime.MinValue)
NotifyDependencyChanged(Me, EventArgs.Empty)
End If
End Sub
' Overrides the DependencyDispose method to set the
' Disposed proerty to true. This method automatically
' notifies the underlying CacheDependency object to
' release any resources associated with this class.
Protected Overrides Sub DependencyDispose()
Disposed = True
End Sub
End Class
