概述
Windows 服务就是运行在windows 系统的一个进程的开发,可以把它做成一个Timer,也可以做成while循环,每隔一段时间起一个线程来运行.
windows install开发是利用msi.dll 提供方法,来安装一个存放有安装程序目录的任务.
windows 服务开发
先在VS中
增加到
在ProjectInstaller.cs中代码设计如下
[RunInstaller(true)] public partial class ProjectInstaller : Installer { public ProjectInstaller() { InitializeComponent(); } }
在ProjectInstaller中代码如下
partial class ProjectInstaller { /// /// Required designer variable. /// private System.ComponentModel.IContainer components = null; /// /// Clean up any resources being used. /// /// true if managed resources should be disposed; otherwise, false. protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } #region Component Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// private void InitializeComponent() { this.serviceProcessInstaller1 = new System.ServiceProcess.ServiceProcessInstaller(); this.serviceInstaller1 = new System.ServiceProcess.ServiceInstaller(); // // serviceProcessInstaller1 // this.serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalSystem; this.serviceProcessInstaller1.Password = null; this.serviceProcessInstaller1.Username = null; // // serviceInstaller1 // this.serviceInstaller1.Description = "用来处理所有的异步操作，如发送邮件，发送短信"; this.serviceInstaller1.DisplayName = "AsynchronismServices"; this.serviceInstaller1.ServiceName = "AsynchronismService"; this.serviceInstaller1.StartType = System.ServiceProcess.ServiceStartMode.Automatic; // // ProjectInstaller // this.Installers.AddRange(new System.Configuration.Install.Installer[] { this.serviceProcessInstaller1, this.serviceInstaller1}); } #endregion private System.ServiceProcess.ServiceProcessInstaller serviceProcessInstaller1; private System.ServiceProcess.ServiceInstaller serviceInstaller1; }
windows install开发
先定义一个MSIInstallerManager类
////// Import the windows installer dll /// internal class MSIInstallerManager { ////// Indicate the WindowsInstaller UI level /// public enum INSTALLUILEVEL { ////// authored UI with wizards, progress, errors /// INSTALLUILEVEL_FULL = 5, } [DllImport("msi.dll")] public static extern uint MsiInstallProduct(string szPackagePath, string szCommandLine); [DllImport("msi.dll", SetLastError = true)] public static extern int MsiSetInternalUI(INSTALLUILEVEL dwUILevel, ref IntPtr phWnd); }
然后增加如下方法
////// Install the specified msi file into local computer /// /// the path of specified msi file ///if the msi file is installed successfully,return true,otherwise return false private bool Installfile(string filePath) { IntPtr myPtr = new IntPtr(); MSIInstallerManager.MsiSetInternalUI(MSIInstallerManager.INSTALLUILEVEL.INSTALLUILEVEL_FULL, ref myPtr); install the specified msi file uint result = MSIInstallerManager.MsiInstallProduct(filePath, string.Empty); if the result value is 0 ,the installation will be completed successfully if (0 == result) { return true; } else { return false; } }
总结
windows服务开发一般用于win service开发,windows install开发用于sofeware update的开发.
