为什么,我已继承了Installer类.在打包,安装时,没有任何反应呢.

//附Installer类using System;namespace MyInstaller
{
/// <summary>
/// MyInstaller 的摘要说明。
/// </summary>

{
public MyInstaller():base()
{
//
// TODO: 在此处添加构造函数逻辑
//

this.Committed+=new System.Configuration.Install.InstallEventHandler(MyInstaller_Committed);
this.Committing+=new System.Configuration.Install.InstallEventHandler(MyInstaller_Committing);
