推荐答案

当你调用 Client.Open 时，如果它关闭，应该抛出一个你可以捕获的异常.
我更喜欢实现一个方法，该方法返回一个名为 Ping 的布尔值.代码基本上只是 return true; 所以它会尽快返回.在客户端，我调用它并捕获异常，如果我得到任何异常，则我知道 Web 服务已关闭.
您可以扩展该模式以执行 PingCheckDB 或 PingCheckX 之类的操作，它们可以执行假/示例测试运行，以便您根据可用内容启用/禁用客户端上的功能.

When you call Client.Open if it is down that should throw an exception which you can trap.
What I prefer to do is implement a method which returns a boolean called Ping. The code basically just does return true; so it returns as quickly as possible. On the client side I call it and trap exceptions, if I get any then I know the web service is down.
You can extend the pattern to do things like PingCheckDB or PingCheckX which can do a fake/sample test run so you enable/disable functionality on the client based on what is available.
