Przykłady

W poniższym przykładzie pokazano InstallException konstruktor. Jest to część przykładu InstallException klasy.

W tym przykładzie Installutil.exe wywołuje metodę Commit . W kodzie zakłada Commit się, że plik o nazwie FileDoesNotExist.txt istnieje przed instalacją zestawu może zostać zatwierdzony. Jeśli plik FileDoesNotExist.txt nie istnieje, Commit zgłasza element InstallException.

virtual void Commit( IDictionary^ savedState ) override
{
   Installer::Commit( savedState );
   Console::WriteLine( "Commit ..." );
   
   // Throw an error if a particular file doesn't exist.
   if (  !File::Exists( "FileDoesNotExist.txt" ) )
         throw gcnew InstallException;

   
   // Perform the final installation if the file exists.
}

public override void Commit(IDictionary savedState)
{
   base.Commit(savedState);
   Console.WriteLine("Commit ...");
   // Throw an error if a particular file doesn't exist.
   if(!File.Exists("FileDoesNotExist.txt"))
      throw new InstallException();
   // Perform the final installation if the file exists.
}

Public Overrides Sub Commit(savedState As IDictionary)
   MyBase.Commit(savedState)
   Console.WriteLine("Commit ...")
   ' Throw an error if a particular file doesn't exist.
   If Not File.Exists("FileDoesNotExist.txt") Then
      Throw New InstallException()
   End If
   ' Perform the final installation if the file exists.
End Sub

W tym przykładzie Installutil.exe wywołuje metodę Uninstall . Odinstalowanie będzie miało miejsce tylko wtedy, gdy plik o nazwie FileDoesNotExist.txt istnieje. W przeciwnym razie zgłasza element InstallException.

virtual void Uninstall( IDictionary^ savedState ) override
{
   Installer::Uninstall( savedState );
   Console::WriteLine( "UnInstall ..." );
   
   // Throw an error if a particular file doesn't exist.
   if (  !File::Exists( "FileDoesNotExist.txt" ) )
         throw gcnew InstallException( "The file 'FileDoesNotExist'  does not exist" );

   
   // Perform the uninstall activites if the file exists.
}

public override void Uninstall(IDictionary savedState)
{
   base.Uninstall(savedState);

         " does not exist");
