compiler-errors - ServiceStack：调用服务时出错

Question

我已经实现了一个 ServiceStack 示例服务，就像在文档中一样 - github.com/ServiceStack/ServiceStack/wiki/Create-your-first-webservice

问题是，当我尝试调用它时，会出现以下错误：

"cannot convert from 'string' to 'ServiceStack.ServiceHost.IReturnVoid'"

和

The best overloaded method match for 'ServiceStack.ServiceClient.Web.ServiceClientBase.Get(ServiceStack.ServiceHost.IReturnVoid)' has some invalid arguments

我调用服务的代码：

var client = new JsonServiceClient("http://host:8080/");
HelloResponse response = client.Get(new Hello { Name = "World!" });

任何人都可以帮忙吗？谢谢。

Answer 1

HelloResponse response = client.Get<string>(new Hello { Name = "World!" });

您必须在这些泛型方法中指定返回类型。
