Remarks

The ProcessModelInfo class is not meant to be instantiated in your own code. Use the static GetCurrentProcessInfo and GetHistory methods to populate ProcessInfo objects, and then use the properties of the ProcessInfo objects to obtain information about the processes.

Note

The GetCurrentProcessInfo and GetHistory methods can be used only with Microsoft Internet Information Services (IIS) version 5.0 on Microsoft Windows 2000 and Windows XP or with IIS 6.0 on Windows Server 2003 and using IIS 5.0 isolation mode. For more information, see How to: Configure ASP.NET Applications for an ASP.NET Version.

Constructors

GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetHistory(Int32)	Returns information about recent worker processes.
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
