关于回调接收短信内容不循环的问题,谢谢

使用SDK开发短信收发平台，收短信使用回调，经过一番修改，终于可正常接收，但是发现一个问题：如果有2条短信需要接收，显示接收到的数据一样，包括号码、内容、时间都是一样的，具体代码如下：



        //引用DLL

        [DllImport("EUCPComm.dll", EntryPoint = "ReceiveSMSEx")]  // 接收短信

        public static extern int ReceiveSMSEx(string sn, deleSQF mySmsContent);

        

        //回调(接收短信)

        static void getSMSContent(string mobile, string senderaddi, string recvaddi, string ct, string sd, ref int flag)

        {

            string mob = mobile;

            string content = ct;

            int myflag = flag;

            //在此处将短信内容存入datatable

            DataRow RecRow = TempDT.NewRow();

            RecRow[0] = mobile;

            RecRow[1] = ct;

            RecRow[2] = sd;

            TempDT.Rows.Add(RecRow);

        }

        public delegate void deleSQF(string mobile, string senderaddi, string recvaddi, string ct, string sd, ref int flag);

        deleSQF mySmsContent = new deleSQF(getSMSContent);

        

        //声明静态的DataTable

        public static DataTable TempDT = new DataTable();

        

        //Form1_Load中初始化DataTable

        private void Form1_Load(object sender, EventArgs e)

        {

            TempDT.Columns.Add("mob");

            TempDT.Columns.Add("con");

            TempDT.Columns.Add("rtime");

        }

        

        //button5单击事件收取短信

        private void button5_Click(object sender, EventArgs e)

        {

            deleSQF mySmsContent = new deleSQF(getSMSContent);

            //接收短信                序列号       函数指针

            int result = 2;

            while (result == 2)  //当result = 2 时，说明还有下一批短信等待接收，这时需重新再调用一次ReceiveSMS方法

            {

                result = ReceiveSMSEx(textBox1.Text, mySmsContent);

                if (result == 1)

                {

                    textBox3.Text += "接收短信成功:"+DateTime.Now.ToString()+"\r\n";

                }

                else if (result == 101)

                {

                    textBox3.Text += "网络故障:" + DateTime.Now.ToString() + "\r\n";

                }

                else if (result == 102)

                {

                    textBox3.Text += "其它故障:" + DateTime.Now.ToString() + "\r\n";

                }

                else if (result == 105)

                {

                    textBox3.Text += "参数指针为空:" + DateTime.Now.ToString() + "'\r\n";

                }

                else if (result == 0)

                {

                    textBox3.Text += "失败:" + DateTime.Now.ToString() + "\r\n";

                }

                else if (result == -1)

                {

                    textBox3.Text += "未知故障:" + DateTime.Now.ToString() + "\r\n";

                }

            }

            //如果TempDT有记录

            if (TempDT.Rows.Count > 0)

            {

                foreach (DataRow row in TempDT.Rows)

                {

                    //显示短信号码、内容、时间。就这里出错，如果有2条未接受短信，点接收时，textBox3中显示接受到的两条记录是一样的

                    textBox3.Text += row[0].ToString() + "/" + row[1].ToString() + "/" + row[2].ToString() + "\r\n";

                }

                清空TempDT

                TempDT.Clear();

            }

        }
