C# Windows服务问题

Question

小弟使用C#写了个Windows服务，把代码放在控制台程序跑，没什么问题，但就是在服务里，然后添加服务的时候就启动不起来，老是提示这个错误：

代码如下：

protected override void OnStart(string[] args)
        {while (true)
                {                    var databaseModels = MongoDBHelper.Select<DataBaseServerConfigures>(Query.EQ("SystemAddress", BsonValue.Create(systemAddress)), MongoConnType.Center);                    var dataModel = MongoDBHelper.Get<ActivityConfigures>(Query.EQ("ActivityName", BsonValue.Create("系统Ping设置")), MongoConnType.Center);                    if (databaseModels.Count > 0)
                    {                        if (dataModel != null)
                        {                            foreach (var item in databaseModels)
                            {
                                MongoDBHelper.Insert<SystemPing>(                                    new SystemPing()
                                    {
                                        ThisIP = prohelper.GetIPAddress(),
                                        PingIP = item.DataBaseName,
                                        SystemAddress = item.SystemAddress,
                                        Status = prohelper.GetSystemPing(item.DataBaseName),
                                        DateTimeNow = DateTime.Now
                                    }, MongoConnType.Center);
                            }
                            Thread.Sleep(dataModel.TntervalSecond);
                        }                        else
                        {                            foreach (var item in databaseModels)
                            {
                                MongoDBHelper.Insert<SystemPing>(                                    new SystemPing()
                                    {
                                        ThisIP = prohelper.GetIPAddress(),
                                        PingIP = item.DataBaseName,
                                        SystemAddress = item.SystemAddress,
                                        Status = prohelper.GetSystemPing(item.DataBaseName),
                                        DateTimeNow = DateTime.Now
                                    }, MongoConnType.Center);
                            }
                            Thread.Sleep(30000);
                        }
                    }

                }
        }

什么原因啊？望大神帮忙看下！！

Answer 1

OnStart中的代码必须放进一个单独的线程中执行，因为服务执行启动之后需要更新当前服务状态，如果在服务主线程中阻塞，就会导致查询服务状态失败，系统认为服务启动失败，所以抛除此错误
