InstallException Konstruktoren

public:
 InstallException();

public InstallException ();

Public Sub New ()

Beispiele

Im folgenden Beispiel wird der InstallException Konstruktor veranschaulicht. Sie ist Teil des Beispiels der InstallException -Klasse.

In diesem Beispiel ruft Installutil.exe die Commit -Methode auf. Der Code in Commit setzt voraus, dass eine Datei mit dem Namen FileDoesNotExist.txt vorhanden ist, bevor ein Commit für die Installation der Assembly ausgeführt werden kann. Wenn die Datei FileDoesNotExist.txt nicht vorhanden ist, Commit löst ein aus 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)

Parameter

Beispiele

Im folgenden Beispiel wird der InstallException Konstruktor veranschaulicht. Sie ist Teil des Beispiels der InstallException -Klasse.

In diesem Beispiel ruft Installutil.exe die Uninstall -Methode auf. Die Deinstallation erfolgt nur, wenn eine Datei mit dem Namen FileDoesNotExist.txt vorhanden ist. Andernfalls wird eine InstallExceptionausgelöst.

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.
End Sub
