我正在使用 C# 并通过自动生成的 C# 代理对象连接到 WebService。我调用的方法可能会运行很长时间,有时会超时。我得到不同的错误,有时我得到 aSystem.Net.WebException
或 a System.Web.Services.Protocols.SoapException
。这些异常具有我可以查询的属性,以查找特定类型的错误,我可以从中向用户显示对人类友好的版本。
但有时我只是得到一个InvalidOperationException
,它有以下消息。有什么方法可以解释这是什么,而无需通过字符串挖掘我认识的东西,感觉很脏,并且与国际化无关,错误消息可能会以不同的语言返回。

编辑:我对网络服务器上的方法进行了尝试。我已经调试过了,web-server 方法返回(大约一分钟后)没有任何异常。我还在 Web 服务中添加了一个未处理的异常处理程序,并且没有命中断点。Web 服务返回后,我会在客户端收到此错误,而不是我预期的结果。
