我可以从电脑向手机发送短信,但我无法从电脑发送多条短信。此代码运行成功,我正在通过 AT 命令发送消息,我搜索了谷歌甚至在 stackoverflow 中,给出的信息与我的要求不匹配,所以我正在编写下面的代码,如果你能给我一些建议,请告诉我。如果您想问我任何其他问题,请告诉我。

我建议为此目的使用 GSMCOMM .NET 库 http://www.scampers.org/steve/sms/libraries.htm

或者如果你有 nuget http://nuget.org/packages/GSMComm/

这个托管库将适合您的目的并为您提供易于使用的 api,因此我建议您使用它并尝试使用它。
