Installer.Committing 事件

在 Installers 属性中的安装程序提交它们的安装前发生。

**命名空间:**System.Configuration.Install
**程序集:**System.Configuration.Install（在 system.configuration.install.dll 中）

语法

声明
Public Event Committing As InstallEventHandler
用法
Dim instance As Installer
Dim handler As InstallEventHandler

AddHandler instance.Committing, handler

public event InstallEventHandler Committing

public:
event InstallEventHandler^ Committing {
    void add (InstallEventHandler^ value);
    void remove (InstallEventHandler^ value);
}

/** @event */
public void add_Committing (InstallEventHandler value)

/** @event */
public void remove_Committing (InstallEventHandler value)

JScript 支持使用事件，但不支持进行新的声明。

示例

下面的示例说明 Committing 事件。它由 OnCommitting 方法引发。

Public Sub New()
   MyBase.New()
   ' Attach the 'Committing' event.
   AddHandler Me.Committing, AddressOf MyInstaller_Committing
End Sub 'New

' Event handler for 'Committing' event.
Private Sub MyInstaller_Committing(ByVal sender As Object, _
                                   ByVal e As InstallEventArgs)
   Console.WriteLine("Committing Event occured.")
End Sub 'MyInstaller_Committing

public MyInstallerClass() :base()
{
   // Attach the 'Committing' event.
   this.Committing += new InstallEventHandler(MyInstaller_Committing);
}
// Event handler for 'Committing' event.
private void MyInstaller_Committing(object sender, InstallEventArgs e)
{
   Console.WriteLine("Committing Event occured.");
}

public:
   MyInstallerClass()
      : Installer()
   {
      // Attach the 'Committing' event.
      this->Committing += gcnew InstallEventHandler( this, &MyInstallerClass::MyInstaller_Committing );
   }

private:
   // Event handler for 'Committing' event.
   void MyInstaller_Committing( Object^ /*sender*/, InstallEventArgs^ /*e*/ )
   {
      Console::WriteLine( "Committing Event occured." );
   }

public MyInstallerClass()
{
    // Attach the 'Committing' event.
    this.add_Committing(new InstallEventHandler(MyInstaller_Committing));
} //MyInstallerClass

// Event handler for 'Committing' event.
private void MyInstaller_Committing(Object sender, InstallEventArgs e)
{
    Console.WriteLine("Committing Event occured.");
} //MyInstaller_Committing
