public:
 virtual bool IsEquivalentInstaller(System::Configuration::Install::ComponentInstaller ^ otherInstaller);

public virtual bool IsEquivalentInstaller (System.Configuration.Install.ComponentInstaller otherInstaller);

abstract member IsEquivalentInstaller : System.Configuration.Install.ComponentInstaller -> bool
override this.IsEquivalentInstaller : System.Configuration.Install.ComponentInstaller -> bool

Public Overridable Function IsEquivalentInstaller (otherInstaller As ComponentInstaller) As Boolean

Parameters

otherInstaller: ComponentInstaller

The installer to compare.

Returns

Boolean

true if this installer and the installer specified by the otherInstaller parameter install the same object; otherwise, false.

Examples

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 = gcnew 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'" );
}

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'");
}

Dim myServiceInstaller As New ServiceInstaller()
' Check whether 'ServiceInstaller' object can handle the same 
' kind of installation as 'EventLogInstaller' object.
If myEventLogInstaller.IsEquivalentInstaller(myServiceInstaller) Then
   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'")
End If

Remarks

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.
