1.左侧工具栏里有Timer控件，但是如果调用的是系统时间，就需要添加System.timer.timer空间下的控件。

2.服务编写之后，还不能由SCM(服务控制管理器)进行管理，需要给该服务添加装载器。在Service1.cs的设计视图，点击右键，选择“添加装载器”，系统默认就会添加ProjectInstaller.cs这个类

添加该类后，在该类的设计视图上可看到serviceInstaller1和serviceProcessInstaller1，分别设置其属性。

设置serviceInstaller1的运行方式为手动或者自动

设置serviceInstaller1的ServiceName,设置为什么，服务列表中就显示什么

设置serviceProcessInstaller1的运行账号为LocalSystem

3.用U盘实现自动升级软件

步骤：
1.软件打包zip
2.读取U盘复制到指定位置
3.关闭软件解压到指定位置
4.启动软件删除zip

3.1 解压缩（难点）
1.下载SharpZipLib.dll ，添加引用，添加一个解压类 UnZipClass.cs

UnZipClass.cs

UnZipClass.cs

///

namespace TestWinform
{
    public class UnZipClass
    {
        public void UnZip(string[] args)
        {
            ZipInputStream s = new ZipInputStream(File.OpenRead(args[0]));

            ZipEntry theEntry;
            while ((theEntry = s.GetNextEntry()) != null)
            {

                string directoryName = Path.GetDirectoryName(args[1]);
                string fileName = Path.GetFileName(theEntry.Name);

                //生成解压目录
                Directory.CreateDirectory(directoryName);

                if (fileName != String.Empty)
                {
                    //解压文件到指定的目录
                    FileStream streamWriter = File.Create(args[1] + theEntry.Name);

                    int size = 2048;
                    byte[] data = new byte[2048];
                    while (true)
                    {
                        size = s.Read(data, 0, data.Length);
                        if (size > 0)
                        {
                            streamWriter.Write(data, 0, size);
                        }
                        else
                        {
                            break;
                        }
                    }

                    streamWriter.Close();
                }
            }
            s.Close();
        }
    }
}

3.2 （启动进程难点）

因为启动进程的用户名是System，开启进程后，不会显示exe的界面，所以必须【模拟用户开启进程】，调用方法

3.3 获取当前工作目录（安装路径）

开始的情况这么写是错误的。

//获取当前工作目录
//string CurrentDirectoryPath = Environment.CurrentDirectory + \\Debug.zip;

由于windows服务安装时，系统会自动将windows服务的程序文件复制到系统目录下，通常是System32目录下，windows服务的运行目录就是系统目录，有时候，windows服务在运行时需要知道自己的安装目录，比如，windows服务运行时所需要的一些资源文件，通常可能是一些声音或图像文件，这些资源文件是位于安装目录下的，只有windows服务知道了安装目录，才能对这些资源文件进行访问，那么windows服务如何知道自己的安装目录的信息呢，一种比较简单的做法是通过访问注册表。

/*
Windows服务在系统安装后会在注册表的 "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\[ServiceName]"下以服务的ServiceName建1个目录，目录中会有"ImagePath"节，这里保存的就是该服务的安装路径。
*/

        //获取注册表的ImagePath路径
        public static string GetWindowsServiceInstallPath(string ServiceName)
        {
            string key = "SYSTEM\\CurrentControlSet\\Services\\" + ServiceName;
            string path = Registry.LocalMachine.OpenSubKey(key).GetValue("ImagePath").ToString();
            path = path.Substring(0, path.LastIndexOf("\\"));
            return path;
        }
