C＃中的Windows服务启动失败 [英] Windows Service in C# Start Failed

问题描述

Hello Everyone，

Hello Everyone,

我有一个用C＃编写的Windows服务，它使用TcpListener来侦听来自客户端的请求。服务已成功安装，但当我尝试运行时，它会向我显示错误消息 

I have a windows service written in C# that is using TcpListener to listen requests from clients. Service is installed successfully, but when i am trying to run it's giving me error message 

以下是OnStart方法中的代码

Here is code in OnStart Method

protected override void OnStart(string[] args)
        {
            TcpListener serverSocket = new TcpListener(8888);
            TcpClient clientSocket = default(TcpClient);
            serverSocket.Start();
            Library.WriteErrorLog("Server Started");
            clientSocket = serverSocket.AcceptTcpClient();
            Library.WriteErrorLog("Ready to Accept");

            while ((true))
            {
                try
                {
                    NetworkStream networkStream = clientSocket.GetStream();
                    string dataFromClient;
                    byte[] bytesFrom = new byte[10025];

                    if (networkStream.DataAvailable)
                    {
                        networkStream.Read(bytesFrom, 0, 100);
                        dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
                        dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf('\0'));

                        Library.WriteErrorLog("Data from Client" + dataFromClient);
                        networkStream.Flush();
                    }
                }
                catch (Exception ex)
                {
                    Library.WriteErrorLog(ex.Message.ToString() + " | Exception in Main");
                }
            }
        }

出现此错误的原因可能是什么。请指导。

推荐答案

答案在错误消息中。 将网络处理移出OnStart方法，以便它立即返回服务控制器。 它可能应该在一个单独的主题中。

The answer is in the error message.  Move the network processing out of the OnStart method so that it returns to the service controller without delay.  It should probably be in a separate thread.
