ProcessInfo Class

Provides information on processes currently executing.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)
[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public class ProcessInfo

This class returns information about ASP.NET worker processes that are running under the ASP.NET process model. Objects of this type are returned by the static methods ProcessModelInfo.GetCurrentProcessInfo and ProcessModelInfo.GetHistory. These methods are the only useful ways to create an initialized object.

NoteNote:

If you are using Microsoft Internet Information Services (IIS) 6.0, process metrics returned by the ProcessInfo classes are available only if you are running in IIS 5.0 isolation mode. If you are using IIS 6.0 in worker process isolation mode, the ASP.NET process model is disabled and an HttpException exception is thrown when you access ProcessInfo members.

The following code example demonstrates using the Age, PeakMemoryUsed, ProcessID, RequestCount, ShutdownReason, StartTime and Status properties of the ProcessInfo class. The example displays a LinkButton. When the LinkButton is clicked, the current process information is displayed.
