Question

我使用内置Qt的VS2010。我正在尝试实现客户端和服务器，使用UDP。我从书Qt4编程GUI C ++中获取了示例。

实现主要基于Qt库QtNetwork，但是当我包含它时，我会收到很多未知的错误，如：

Error 8 error C2653: 'System' : is not a class or namespace name ****\AssemblyInfo.cpp 3
Error 9 error C2871: 'Reflection' : a namespace with this name does not exist ****AssemblyInfo.cpp 3

我认为错误是该库QtNetwork未正确包含的结果。你能否告诉我如何解决这个问题？！

我试图通过自己的方式解决它，并采取以下行动：

在VS：Qt \ Qt项目设置中\添加网络库，然后qmake -project，qmake，nmake
在.pro文件中添加了字符串QT += network，然后qmake -project，qmake，nmake

他们都未能应对陈述的问题。

#pragma once

#include <QWidget>
#include "QtNetwork"
#include <QtGui>

class QTimer;
class QUdpSocket;

 class NetworkManagerServer : public QWidget
 {
     Q_OBJECT

 public:
     NetworkManagerServer(QWidget *parent = 0);

 private slots:
     void sendDatagramm();
 private:
     QUdpSocket* m_udpSocket;
     QTimer* m_timer;
     int m_messageNo;
 };

#include "NetworkManagerServer.h"

 NetworkManagerServer::NetworkManagerServer(QWidget *parent)
     : QWidget(parent)
 {
     m_timer = new QTimer(this);
     m_timer->start(2 * 1000);
     m_udpSocket = new QUdpSocket(this);
     m_messageNo = 1;

     connect(m_timer, SIGNAL(timeout()), this, SLOT(broadcastDatagram()));

 }

 void NetworkManagerServer::sendDatagramm(void)
 {
     QByteArray datagramm;
     QDataStream out (&datagramm, QIODevice::WriteOnly);
     //out.setVersion(QDataStream::Qt_4_8);
     out << "Hellow Qt::Network!";
     m_udpSocket->writeDatagram(datagramm, QHostAddress::LocalHost,5824);
 }

以下是我收到的错误列表：

Error   8   error C2653: 'System' : is not a class or namespace name    ***\AssemblyInfo.cpp    3
Error   9   error C2871: 'Reflection' : a namespace with this name does not exist   ***AssemblyInfo.cpp 3
Error   10  error C2653: 'System' : is not a class or namespace name    ***AssemblyInfo.cpp 4
Error   11  error C2871: 'CompilerServices' : a namespace with this name does not exist ***AssemblyInfo.cpp 4
Error   12  error C2653: 'System' : is not a class or namespace name    ***AssemblyInfo.cpp 5
Error   13  error C2871: 'InteropServices' : a namespace with this name does not exist  ***AssemblyInfo.cpp 5

等等

我发现那是问题！ 1.我创建了单元测试，后来将它们从项目中删除，但是t removed from folder as result lots of errors, which i presented here 2. I tried to include QtNetwork with < > , but it didn没有工作3.但是当我在qmake -project，qmake，nmake和生成的.pro文件中包含字符串QT + =网络项目已成功编译！

虽然包括QtNetwork我遇到了很多错误
