我开始在 Android 上使用 mono droid 或 Xamarin，所以，我的想法是重用我已经在 .NET 中使用的大部分代码。
我需要我的 android 和 ios 应用程序做的一件事是调用使用 wcf rest 和 json 编码提供的 Web 服务。
所以我的代码很简单：
WebHttpBinding webBinding = new WebHttpBinding();
EndpointAddress endPointAddress = new EndpointAddress("http://192.168.126.24:8025/Services/SecurityManagement");
ChannelFactory<ISecurityManagement> newFactory = new ChannelFactory<ISecurityManagement>(webBinding, endPointAddress);
newFactory.Endpoint.Behaviors.Add(new WebHttpBehavior() { DefaultOutgoingRequestFormat = System.ServiceModel.Web.WebMessageFormat.Json, DefaultOutgoingResponseFormat = System.ServiceModel.Web.WebMessageFormat.Json });
newFactory.Endpoint.Behaviors.Add(new RestEndPointBehavior());
ISecurityManagement newProxy = newFactory.CreateChannel();
ValidateUserExistenceOutput output = newProxy.ValidateUserExistence(new ValidateUserExistenceInput() { Domain = "CRITICAL", Username = "myUserName" });
足够简单让我开始（至少，这是我对单声道的想法，在.net中重用单声道）
但是当我运行此代码时，我得到以下异常异常：

我在 .NET 4.5 应用程序中使用完全相同的代码，它工作正常，似乎在将对象转换为字符串（我想是 json 字符串）时它失败了。
既然它在.NET中工作，它应该直接在单声道中工作吗？
你们有具有复杂输入对象的服务吗？您使用什么 api 进行这些调用？
提前感谢您的所有帮助，
