Installs an executable containing classes that extend ServiceBase. This class is called by installation utilities, such as InstallUtil.exe, when installing a service application.
Assembly: System.ServiceProcess (in System.ServiceProcess.dll)
Gets or sets the type of account under which to run this service application.
Gets a value indicating whether the component can raise an event.(Inherited from Component.)
Gets or sets information about the current installation.(Inherited from Installer.)
Gets help text displayed for service installation options.(Overrides Installer.HelpText.)
Gets the collection of installers that this installer contains.(Inherited from Installer.)
Gets or sets the installer containing the collection that this installer belongs to.(Inherited from Installer.)
Gets or sets the password associated with the user account under which the service application runs.
Gets or sets the user account under which the service application will run.
When overridden in a derived class, completes the install transaction.(Inherited from Installer.)
Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.(Inherited from MarshalByRefObject.)
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Serves as the default hash function. (Inherited from Object.)
Retrieves the current lifetime service object that controls the lifetime policy for this instance.(Inherited from MarshalByRefObject.)
Obtains a lifetime service object to control the lifetime policy for this instance.(Inherited from MarshalByRefObject.)
Writes service application information to the registry. This method is meant to be used by installation tools, which call the appropriate methods automatically.(Overrides Installer.Install(IDictionary).)
Determines if the specified installer installs the same object as this installer.(Inherited from ComponentInstaller.)
Rolls back service application information written to the registry by the installation procedure. This method is meant to be used by installation tools, which process the appropriate methods automatically.(Overrides Installer.Rollback(IDictionary).)
When overridden in a derived class, removes an installation.(Inherited from Installer.)
Thedoes work common to all services in an executable. It is used by the installation utility to write registry values associated with services you want to install.
To install a service, create a project installer class that inherits from Installer, and set the RunInstallerAttribute on the class to true. Within your project, instantiate one instance per service application, and one ServiceInstaller instance for each service in the application. Finally, add the instance and the ServiceInstaller instances to your project installer class.
When InstallUtil.exe runs, the utility looks for classes in the service assembly with the RunInstallerAttribute set to true. Add classes to the service assembly by adding them to the Installers collection associated with your project installer. If RunInstallerAttribute is false, the install utility ignores the project installer.
For an instance of Username and Password pair under which the service should run, or you can use Account to specify that the service run under the computer's System account, a local or network service account, or a user account., properties you can modify include specifying that a service application run under an account other than the logged-on user. You can specify a particular
The computer's System account is not the same as the Administrator account.
Normally, you do not call the methods on ServiceInstaller within your code; they are generally called only by the install utility. The install utility automatically calls the ServiceProcessInstaller.Install and ServiceInstaller.Install methods during the installation process. It backs out failures, if necessary, by calling Rollback (or ServiceInstaller.Rollback) on all previously installed components.
An application's install routine maintains information automatically about the components already installed, using the project installer's Installer.Context. This state information is continuously updated as the instance and each ServiceInstaller instance is installed by the utility. It is usually unnecessary for your code to modify this state information explicitly.
Instantiating a ComponentInstaller, to be called.causes the base class constructor,
The following example creates a project installer called MyProjectInstaller, which inherits from Installer. It is assumed there is a service executable that contains two services, "Hello-World Service 1" and "Hello-World Service 2". Within the constructor for MyProjectInstaller (which would be called by the install utility), ServiceInstaller objects are created for each service, and a is created for the executable. For the install utility to recognize MyProjectInstaller as a valid installer, the RunInstallerAttribute attribute is set to true.
Optional properties are set on the process installer and the service installers before the installers are added to the Installers collection. When the install utility accesses MyProjectInstaller, the objects added to the Installers collection through a call to InstallerCollection.Add will be installed in turn. During the process, the installer maintains state information indicating which objects have been installed, so each object can be backed out in turn in case of an installation failure.
Normally, you would not instantiate your project installer class explicitly. You would create it and add the RunInstallerAttribute, but the install utility actually calls, and therefore instantiates, the class.
