從模式中提取文本

Question

我有一個 sim 800 模塊。 我閱讀了存儲在 SIM 卡中的所有消息。 返回下面的響應。 我想要單獨的電話號碼、時間和回復文本。 但我不知道怎么做

OK

Answer 1

這可能不是最好的方法，但考慮到您的響應結構將始終保持不變，請考慮：

\+CMGL:\s\d+\,\"REC\sREAD\",\"(?<phone>.+)\",\"(?:.+)?\",\"(?<time>.+)\"|^(?<message>.+)$

正則表達式演示

本質上，捕獲整個字符串並通過組提取必要的信息。 您可以通過組名訪問各個組（參見右側的鏈接）。

您應該對此進行調查以解決您的問題。 https://www.tutorialspoint.com/csharp/csharp_regular_expressions.htm

或者，您也可以使用字符串拆分方法來划分逗號之間的內容。 https://www.geeksforgeeks.org/string-split-method-in-c-sharp-with-examples/
