昨天寫了短信的發送，今天我們在來談談如果讀取SIM卡中的短信息，然后將SIM中經過編碼的內容進行解碼。
首先，我們熟悉幾個讀取短信的AT命令：
AT+CMGL=0 讀取電話上全部未讀過的SMS消息
AT+CMGL=2
列出已有的短信息
AT+CMGL=4 讀取全部SMS消息
AT+CMGR=X 讀取第X條短消息
使用串口工具MCOM，可以調試以上幾條命令，具體方法就不談了。下面談談如果完整的讀取完緩沖區中所有的短信和如何對短信進行解碼
1.初始化串口，打開串口
1
var serialPort =
new SerialPort(
"
COM6
",
115200, Parity.None,
8, StopBits.One)
2 {
3 WriteTimeout = 500,
4 ReadTimeout = 5000,
5 RtsEnable = true,
6 DtrEnable = true
7 };
8 serialPort.Open();
2 {
3 WriteTimeout = 500,
4 ReadTimeout = 5000,
5 RtsEnable = true,
6 DtrEnable = true
7 };
8 serialPort.Open();
2.設置發送命令格式：
AT+CMGF=0\r
1 serialPort.Write(SMSUtil.GenSendFormatCmd());
2 Thread.Sleep( 500);
3 var result = ReadBuffer(serialPort);
4 Console.WriteLine(result);
2 Thread.Sleep( 500);
3 var result = ReadBuffer(serialPort);
4 Console.WriteLine(result);
3.讀取全部的SMS信息：
AT+CMGL=4\r
1 serialPort.Write(SMSUtil.GenGetList(MessageListType.All));
2 Thread.Sleep( 500);
3 Console.WriteLine(ReadBuffer(serialPort));
2 Thread.Sleep( 500);
3 Console.WriteLine(ReadBuffer(serialPort));
4.讀取返回接收緩沖區的內容
這里需要介紹一下接收時的作法，因為之前我試的時候，一直沒能接收完整。
1
///
<summary>
2 /// 讀取緩沖區的內容
3 /// </summary>
4 /// <param name="serialPort"> The serial port. </param>
5 /// <returns></returns>
6 private static string ReadBuffer(SerialPort serialPort)
7 {
8 var len = serialPort.BytesToRead;
9 var result = new StringBuilder();
10 while (len > 0)
11 {
12 var buffer = new byte[len];
13 serialPort.Read(buffer, 0, len);
14 result.Append(Encoding.ASCII.GetString(buffer));
15
16 Thread.Sleep( 500);
17 len = serialPort.BytesToRead;
18 }
19 return result.ToString();
20 }
2 /// 讀取緩沖區的內容
3 /// </summary>
4 /// <param name="serialPort"> The serial port. </param>
5 /// <returns></returns>
6 private static string ReadBuffer(SerialPort serialPort)
7 {
8 var len = serialPort.BytesToRead;
9 var result = new StringBuilder();
10 while (len > 0)
11 {
12 var buffer = new byte[len];
13 serialPort.Read(buffer, 0, len);
14 result.Append(Encoding.ASCII.GetString(buffer));
15
16 Thread.Sleep( 500);
17 len = serialPort.BytesToRead;
18 }
19 return result.ToString();
20 }
上面這段代碼，采用了循環讀取緩沖區的作法，直到返回的字節數為0，則判斷當前已經把緩沖區的所有短信讀取完畢。這里要注意，在進行下一次讀取時，一定要先休眠500毫秒或者更多，否則此時緩沖區中的字節數為0，嗯，這里沒時間研究，不知道是什么原因，求大神指點。當然，應該不是緩沖區不足的原因。之前我沒有休眠直接讀取時，第一次的返回都只能讀取一條短信，不超過200字節，然后重新打開串口，就能返回之后的所有短信內容。
當然，上面的代碼是阻塞式的，效率肯定不高，但是還沒想到怎么優化。
返回的內容如下：
AT+CMGF=0
OK
AT+CMGL=0
+CMGL: 8,0,,58
0891683108705505F0040D91683115509050F00000217040518530232B207499CD7EB3DA61B93DED66B9DF77103DDD2E83D273900C1693BD6E2F1A2816D3C56A3A180E

0891683108705505F0040D91683115509050F00000217040518511232AE8329BFD66B5C3727BDACD72BFEF207ABA5D06A5E720192C267BDD5E34502CA68BD574301C
+CMGL: 10,0,,57
0891683108705505F0040D91683115509050F00000217040518591232AE8329BFD66B5C3727BDACD72BFEF207ABA5D06A5E720192C267BDD5E34502CA68BD574301C
第一行的+CMGL:8,0,,58的格式如下：+CMGL:[當前信息在SIM卡中的索引],[是否已讀取],,[返回串的字節長度]
第二行為實際的返回串，包括了信息發送服務中心的號碼，發送的時間戳，發送者的號碼，發送內容等。具體的解碼參考下面的代碼
