C# WIN服务实现窗体

使用方法

要注意的是 安装服务后 设置服务让可以与用户交互。

1.  protected override void OnStart(string[] args)
2.         {
3.             Thread _TestForm = new Thread(new ThreadStart(StartListen));
4.             _TestForm.Start();
5.         }
8.         public void StartListen()
9.         {
10.       
11.             Zgke.WindowFrom.Service.ServerWindows.ServiceForm(EventLog);
12.             System.Windows.Forms.Form _MyForm = new System.Windows.Forms.Form();
13.             _MyForm.Text = "打开窗体 Application";
14.             
15.            
16.             System.Windows.Forms.Application.Run(_MyForm);
17.             while (true)
18.             {
19.                 Thread.Sleep(100000);
20.             }            
21.         }

 

下面是全部类
