using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration.Install;
using System.ServiceProcess;
using System.Windows.Forms;
using System.Management;namespace SurveyorLayerControl
{
    [RunInstaller(true)]
    public partial class ProjectInstaller : Installer
    {
        public ProjectInstaller()
        {
            InitializeComponent();
            this.AfterInstall += new InstallEventHandler(ProjectInstaller_AfterInstall);
            this.BeforeInstall += new InstallEventHandler(ProjectInstaller_BeforeInstall);
            this.serviceInstaller1.ServiceName = "MyService";
            this.serviceInstaller1.DisplayName = "Dummy Service";
        }        void ProjectInstaller_BeforeInstall(object sender, InstallEventArgs e)
        {
            //check for required the Services.
            //ServiceController[] sc = ServiceController.GetServices();
            //bool Required_Services_Found = false;
            //for (int i = 0; i < sc.Length; i++)
            //{
            //    if (sc[i].ServiceName.ToLower() == "myservice")
                //{
            //        Required_Services_Found = true;
            //        break;
            //    }
            //}
            //
            //Required_Services_Found = true; //just for testing purposed. this will be removed.
            //
            ServiceController sc = new ServiceController(this.serviceInstaller1.ServiceName); 
//如果你要找的是你这个相同的服务的话， 那this.serviceInstaller1.ServiceName就应该是你的windows service的名字了。
//注意DisplayName and ServiceName是不同的. 在你的代码里，如果你在某些地方更改了ServiceName,那上面的这一行代码就找不到你的service,
//你也可以用：ServiceController sc = new ServiceController("服务名称"); 
            if (sc != null) //如果不是null,那这个服务就是存在的了。
            {
                MessageBox.Show("对不起,\n在您的系统中已经安装有本服务，请按确定退出安装.......", "安装错误", MessageBoxButtons.OK, MessageBoxIcon.Stop);
                Application.Exit();
            }
        }        void ProjectInstaller_AfterInstall(object sender, InstallEventArgs e)
        {
            //Starts up the Service.
            ServiceController sc = new ServiceController(this.serviceInstaller1.ServiceName);
            if (sc != null)
            {
                //sc.Start();
                //
                //sc.WaitForStatus(ServiceControllerStatus.Running);
                //MakeServiceInteractive();
            }
        }    }

Answer 2

兄弟们，System.ServiceProcess and System.Management,在.net 1.1下没有呀。
有没有谁给给出.NET 1.1下的解决方案???

Answer 3

谁说1.1没有 System.ServiceProcess？
你要自己添加reference. 默认是没有的， 因为这个namespace不是在mscorlib里。
