SMS 的 .NET 代码

HI all.

我正在编写一些代码来通过 Zeep Mobile 发送/接收短信（http://zeepmobile.com/developers/ http://zeepmobile.com/developers/).

我查看了他们的谷歌群组，甚至联系了他们的支持人员，但他们不太善于沟通，我现在真的很盲目。

我必须与它们集成（工作需要它），我不确定为什么我的代码不起作用。因此，我想知道是否有人有任何不介意共享的 C# .Net 代码，以便我可以将其集成到我的应用程序中。

当然，这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，我真的很感谢你的帮助。

**

编辑：我已在此处添加源代码，以防任何人可以提供帮助！

**

请原谅草率的代码。这只是我为了测试 Zeep 而拼凑起来的东西，我希望有人可以尝试一下。 （.Net 3.5 控制台应用程序，以防您想要构建它）。

Error

当我运行此代码时发生的情况是下图所示的错误。

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，以查看上面的内容与服务器期望的内容之间是否存在差异。

我已经让它发送消息并返回 HTTP 200 OK 响应。再说一次，这段代码还没有准备好投入生产，它只是用来测试的，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，我希望这可以帮助您。
