c# - 短信的 .NET 代码

Question

大家好。

我正在编写一些代码以通过 Zeep Mobile ( http://zeepmobile.com/developers/) 发送/接收 SMS 消息。

我查看了他们的谷歌群组，甚至联系了他们的支持人员，但他们不太擅长回复，我现在真的是瞎了眼。

我必须与他们整合(工作需要)，但我不确定为什么我的代码无法正常工作。所以，我想知道是否有人愿意分享任何 C# .Net 代码，以便我可以将其集成到我的应用程序中。

当然，这完全取决于您是否有使用 Zeep 的经验。如果你想让我发布我的代码，我也可以这样做。让我知道。

谢谢，非常感谢您的帮助。

**

编辑:我在这里添加了源代码以防任何人可以帮助解决这个问题!

请原谅草率的代码。它只是我用来测试 Zeep 的东西，我希望有人能试一试。 (.Net 3.5 控制台应用程序，以防您想要构建它)。

错误

运行此代码时发生的错误如下图所示。

Answer 1

解决方案:

好的。我昨晚一直在努力，取得了一些进展。我使用 Fiddler 构建 POST 消息，以查看我上面的内容与服务器预期的内容之间的任何差异。

我已经让它发送消息并返回 HTTP 200 OK 响应。同样，这段代码还没有准备好生产，它只是用来测试，看看我是否能让 Zeep 工作。感谢所有回复的人，如果您正在寻找 ZEEP 代码，希望这对您有所帮助。
