InstallException Construtores

public:
 InstallException();

public InstallException ();

Public Sub New ()

Exemplos

O exemplo a seguir demonstra o InstallException construtor . Ele faz parte do exemplo da InstallException classe .

Neste exemplo, Installutil.exe chama o Commit método . O código em Commit presume que exista um arquivo chamado FileDoesNotExist.txt antes que a instalação do assembly possa ser confirmada. Se o arquivo FileDoesNotExist.txt não existir, Commit gerará um 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

public:
 InstallException(System::String ^ message);

public InstallException (string message);

new System.Configuration.Install.InstallException : string -> System.Configuration.Install.InstallException

Public Sub New (message As String)

Neste exemplo, Installutil.exe chama o Uninstall método . A desinstalação só ocorrerá se existir um arquivo chamado FileDoesNotExist.txt . Caso contrário, ele gerará um 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);
   Console.WriteLine("UnInstall ...");
   // Throw an error if a particular file doesn't exist.
   if(!File.Exists("FileDoesNotExist.txt"))
      throw new InstallException("The file 'FileDoesNotExist'" +
         " does not exist");
   // Perform the uninstall activites if the file exists.
}

Public Overrides Sub Uninstall(savedState As IDictionary)
   MyBase.Uninstall(savedState)
   Console.WriteLine("UnInstall ...")
   ' Throw an error if a particular file doesn't exist.
   If Not File.Exists("FileDoesNotExist.txt") Then
      Throw New InstallException("The file 'FileDoesNotExist'" + " does not exist")
   End If
   ' Perform the uninstall activites if the file exists.
