如何获取号码、消息和日期时间并显示到网格

Question

您好，我正在开发一个接收 SMS 的应用程序，我有通过发送 SMS 使用 AT COMMANDS 的经验。我要如何获取发件人#、消息和文本的日期时间。

port.Write("AT+CNMI=2,1,0,0,1")
        Thread.Sleep(1000)
        port.Write("AT+CMGF=1")
        Thread.Sleep(1000)
        port.Write("AT+CMGL=" & "ALL")
        Thread.Sleep(1000)
        receivedData = port.ReadExisting

我想像下图一样显示我的数据网格中的所有消息，但我不知道该怎么做。

dgv.Rows.Add(New String() {"", "", ""})

假设 receivedData 包含这样一个字符串

GLOBE Your balance is something 8/21/2015 7:20:35 AM

并且name/number不能包含空格，你可以像这样将三个部分分开

Dim startMessage As Integer = receivedData.IndexOf(" ")
Dim endMessage As Integer = receivedData.Substring(0, receivedData.Length - 17).LastIndexOf(" ")
Dim id, message, timestamp As String 
If startMessage >=0 AndAlso endMessage > startMessage Then
    id = receivedData.Substring(0, startMessage)
    message = receivedData.Substring(startMessage + 1, endMessage - startMessage - 1).Trim
    timestamp = receivedData.Substring(endMessage + 1)
    dgv.Rows.Add({id, message, timestamp})
End If
