OPC UA 客户端 连接 服务器返回的 EndpointUrl 为什么会变成opc:tcp://0.0.0.0:4840

[ChenMooMo]

客户端传过去的 Url 为 opc.tcp://190.160.9.219:4840 处理完后得到的 endpoint.EndpointUrl=opc.tcp://0.0.0.0:4840，为什么会这样呢？

代码：

public void Connect(string Url)
        {
            try
            {
                // Create the configuration.     
                ApplicationConfiguration configuration = Helpers.CreateClientConfiguration();

                // Create the endpoint description.
                EndpointDescription endpointDescription = Helpers.CreateEndpointDescription(Url);

                // Create the endpoint configuration (use the application configuration to provide default values).
                EndpointConfiguration endpointConfiguration = EndpointConfiguration.Create(configuration);

                // The default timeout for a requests sent using the channel.
                endpointConfiguration.OperationTimeout = 300000;

                // Use the pure binary encoding on the wire.
                endpointConfiguration.UseBinaryEncoding = true;

                if (endpoint.UpdateBeforeConnect)
                {
                    endpoint.UpdateFromServer(bindingFactory);
                    endpointDescription = endpoint.Description;
                    endpointConfiguration = endpoint.Configuration[code=csharp]
