C# 开发Windows Service

1.新建项目

2. 找到Service1.cs

3.修改2个方法的内容


//服务启动的时候 调用
 protected override async void OnStart(string[] args)
        {
            while (true)
            {
                await Task.Run( () =>
                {
                  
                    FileStream fs1 = new FileStream(@"d:\xx.txt", FileMode.OpenOrCreate, FileAccess.Write);
                    StreamWriter sw1 = new StreamWriter(fs1);
                    sw1.BaseStream.Seek(0, SeekOrigin.End);
                    sw1.WriteLine("WindowsService: Service Started" + DateTime.Now.ToString() + "\n");
                    sw1.Flush();
                    sw1.Close();
                    fs1.Close();
                });
                await Task.Delay(1000);
            }
      
        }
//服务关闭的时候调用
        protected override void OnStop()
        {
            FileStream fs = new FileStream(@"d:\xx.txt", FileMode.OpenOrCreate, FileAccess.Write);
            StreamWriter sw = new StreamWriter(fs);
            sw.BaseStream.Seek(0, SeekOrigin.End);
            sw.WriteLine("WindowsService: Service Stopped" + DateTime.Now.ToString() + "\n");
            sw.Flush();
            sw.Close();
            fs.Close();
        }
