C#開發可以可視化操作的windows服務

C#開發可以可視化操作的windows服務

使用C#開發自定義windows服務是一件十分簡單的事。那麼什麼時候，我們需要自己開發windows服務呢，就是當我們需要計算機定期或者一直執行我們開發的某些程序的時候。這裡我以一個WCF的監聽服務為例，因為我是做一個局域聊天室，需要服務器端監聽終端，所以我就開發了一個服務，以便控制此監聽服務。然而，我們開發的windows服務，默認情況下是無法可視化的操作的，這裡我就額外的開發一個工具來對此服務進行操作，效果圖如下：

開發步驟：

1、“新建項目”——“Window服務”

Program.cs代碼：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.ServiceProcess;

namespace MSMQChatService
{
    class Program
    {
        static void Main()
        {
            #region 服務啟動入口，正式用

            ServiceBase[] ServicesToRun;
            ServicesToRun = new ServiceBase[] {  new MQChatService()  };
            ServiceBase.Run(ServicesToRun);

            #endregion
        }
    }

MQChatService.cs代碼如下：

protected override void OnStart(string[] args)
        {
            //開啟服務  這裡就是你想要讓服務做的操作
            StartService();
        }

3、切換到MQChatService的可視化界面

4、在可視化界面，單擊鼠標右鍵，

將會出現一個Installer為後綴的新界面，默認好像是Project Installer.cs，我這裡將其重命名為ServiceInstaller.cs

好了，我們的windows服務已經開發好了，接下來就開發一個可視化的控制器，來控制服務的安裝、卸載、啟動和停止。

1、 新建一個windows程序，名稱ServiceSetup，Form1重命名為FrmServiceSetup，

界面控件如下：

Program.cs代碼如下：

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace ServiceSetup
{
    static class Program
    {
        /// 

        /// 應用程序的主入口點。
        /// 
        [STAThread]
        static void Main()
        {
            Process[] processes = System.Diagnostics.Process.GetProcessesByName(Application.CompanyName);
            if (processes.Length > 1)
            {
                MessageBox.Show("應用程序已經在運行中。");
                Thread.Sleep(1000);
                System.Environment.Exit(1);
            }
            else
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new FrmServiceSetup());
            }
        }
    }
}

主界面代碼：

            InitializeComponent();
            strServiceName = string.IsNullOrEmpty(lblServiceName.Text) ? "MSMQChatService" : lblServiceName.Text;
            InitControlStatus(strServiceName, btnInstallOrUninstall, btnStartOrEnd, btnGetStatus, lblMsg, gbMain);
        }
