ComponentInstaller.IsEquivalentInstaller Method

Typically, IsEquivalentInstaller returns true only if this installer and the installer specified by the otherInstaller parameter install the same object. In such a case, calling the Install or Uninstall method on either installer results in the same system state.

The following example defines a class MyInstallClass, which creates the event log and copies the properties of the event log component to the EventLogInstaller object. It also checks whether ServiceInstaller object can handle the same kind of installation as EventLogInstaller.

ServiceInstaller myServiceInstaller = new  ServiceInstaller();
// Check whether 'ServiceInstaller' object can handle the same 
// kind of installation as 'EventLogInstaller' object.
if(myEventLogInstaller.IsEquivalentInstaller(myServiceInstaller))
{
   Console.WriteLine("'ServiceInstaller' can handle the same kind" 
                     +" of installation as EventLogInstaller");
}
else
{
    Console.WriteLine("'ServiceInstaller' can't handle the same" 
                 +" kind of installation as 'EventLogInstaller'");
}
