我试图在有/没有 SSL/TLS 或端点的情况下捕获 wcf sercue 的所有异常，如下所示：

try
        {
            ServiceReference.ServiceClient serviceClient = new ChartLogicServiceClient();
            serviceClient.Open();
            serviceClient.Login("", "", "");
        }
        catch (SecurityNegotiationException negotiationException)
        {
            // Could not establish trust relationship for the SSL/TLS secure channel with authority 'localhost'.
            throw;
        }
        catch (ArgumentException argumentException)
        {
            // transport wrong config : The provided URI scheme 'https' is invalid; expected 'http'.
            //if (argumentException.Message == "The provided URI scheme 'http' is invalid; expected 'https'.\r\nParameter name: via")
            throw;
        }
        catch (MessageSecurityException messageSecurityException)
        {
            // transport wrong config: The HTTP request was forbidden with client authentication scheme 'Anonymous'.
            //- HTTP Request Error
            if (messageSecurityException.InnerException.Message == "The remote server returned an error: (403) Forbidden.")
            {
                throw;
            }
            else if (messageSecurityException.InnerException.Message == "The remote server returned an error: (404) Forbidden.")
            {
                throw;
            }
        }
        catch (EndpointNotFoundException endpointNotFoundException)
        {
            // no endpoint was found or IIS on server was turned off

        }

我可以在不调用任何方法的情况下检查 wcf 服务的可用性（我尝试过 Open() 但根本不起作用）？不确定我是否从 WCF 服务中捕获所有异常情况？我的目的是如果客户端在 SSL/TSL 或没有端点时遇到 wcf 异常，我应该运行一个小型实用程序控制台来修复客户端上的 app.config 以映射到 wcf 端点和 . 我真的需要你的建议。谢谢

您可以随时尝试连接到服务的 URL 并检查响应代码。也许不是最好的方法，但它应该工作。例如

GET mysite/myservice.svc

并检查 HTTP 状态代码。
