我创建了一个WCF服务，可以从SQL数据库检索数据，并将数据更新和修改回SQL数据库。我正在尝试从Xamarin for Android和Xamarin for iOS调用WCF方法。我搜索了很多例子，想知道如何通过Xamarin for Android和Xamarin for iOS调用WCF服务的PUT和POST方法，但没有成功。下面是参考的WCF代码...我甚至创建了Web API，但所有消费Web API的示例和教程都是关于如何调用GET方法的。我没有看到任何参考文档，可以展示如何跨平台调用WCF或Web API的PUT或Post方法。我已经通过Fiddler测试了WCF服务并且工作正常。下一步应该怎么做呢？我使用SlsvcUtil.exe创建了这个Web服务的代理，就像Xamarin文档中提到的那样。有人能发一个Xamarin.Android的例子来调用下面WCF服务的更新或删除方法吗？非常需要帮助。服务包含webHttp绑定。
