以下示例创建继承 类的 Installer 自定义卸载程序。 在重写 Uninstall 的函数中 UninstallAction ，枚举是根据用户输入设置的。 如果输入为“n”，则自定义卸载程序不会对用户输入的事件日志中的资源执行任何操作。 否则，它将从事件日志中删除资源。

C#

using System;
using System.Diagnostics;
using System.Collections;
using System.ComponentModel;
using System.Configuration.Install;

[RunInstaller(true)]
public class MyUninstallActionClass : Installer
{
   EventLogInstaller myInstaller = new EventLogInstaller();

   // Override the 'Install' method.
   public override void Install(IDictionary savedState)
   {
      Console.Write("Enter a new log to create (eg: MyLog ): ");
      myInstaller.Log = Console.ReadLine();
      Console.Write("Enter a source for log (eg: MySource ): ");
      myInstaller.Source = Console.ReadLine();
      Installers.Add( myInstaller );
      base.Install(savedState);
   }

   // Override the 'Commit' method.
   public override void Commit(IDictionary savedState)
   {
      base.Commit(savedState);
   }

   // Override the 'Rollback' method.
   public override void Rollback(IDictionary savedState)
   {
      base.Rollback(savedState);
   }
   public override void Uninstall(IDictionary savedState)
   {
      Console.Write("Enter a source from log to uninstall(eg: MySource ): ");
      myInstaller.Source = Console.ReadLine();

      Console.Write("Do you want to uninstall, press 'y' for 'YES' and 'n' for 'NO':");
      string myUninstall = Console.ReadLine();

      if( myUninstall == "n" )
      {
         // No action to be taken on the resource in the event log.
         myInstaller.UninstallAction = System.Configuration.Install.UninstallAction.NoAction;
      }
      else
      {
         // Remove the resource from the event log.
         myInstaller.UninstallAction = System.Configuration.Install.UninstallAction.Remove;
      }
      Installers.Add( myInstaller );
      base.Uninstall(savedState);
   }
   public static void Main()
   {
      Console.WriteLine("Syntax for install: installutil.exe UninstallAction_NoAction_Remove_3.exe ");
      Console.WriteLine("Syntax for uninstall: installutil.exe /u "
         +"UninstallAction_NoAction_Remove_3.exe ");
   }
}
