因为加了：

复制

AppTaskMessage& AppTaskMessage::operator =(const AppTaskMessage& other)

{



        if(this == &other)

        {

        

                return *this;

        }

      this->m_AppMessageType = other.m_AppMessageType;

        this->m_dwMessagePriority = other.m_dwMessagePriority;

        this->m_strMessageId = other.m_strMessageId;

        this->m_strFullPathFileName = other.m_strFullPathFileName;

        this->m_strTargetFullPathFileName = other.m_strTargetFullPathFileName;

        this->m_strFilePrefix = other.m_strFilePrefix;

        this->m_strIpaddr = other.m_strIpaddr;

        this->m_dwPort = other.m_dwPort;

        this->m_dwTsNo = other.m_dwTsNo;

        this->m_dwRepeatTimes = other.m_dwRepeatTimes;

        this->m_unMessagePara = other.m_unMessagePara;

        this->m_dwTaskTimeTick = other.m_dwTaskTimeTick;

      this->m_TaskProperty = other.m_TaskProperty;

        return *this;

}

重载了 “=”后，反而赋值的时候，这里不能由遗漏，否则就，呵呵了
